摘 要
博泽公司拥有超过 100 年历史，是汽车行业领先的供应商。它生产为不同的
目而服务的多种产品。然而，这些产品具有一个共同点，那就是，他们全部都是
机电一体化设备。随着机电一体化学科的发展，越来越多的研发途径被发明。模
拟，作为在开发机电一体化设备当中的一种创新方法，正吸引着越来越多的关
注。博泽公司使用 BroSAnT，博泽模拟分析工具，作为其仿真模拟其平台。然而
在使用模拟技术时，我们需要注意的非常重要的一点是模拟结果的质量在很大程
度上取决于模型的质量，而这正是本论文的来源。交叉臂摇窗机系统模型的开发
目的是丰富 BroSAnT 的组件库。本论文的研究工作主要分为以下几个部分。
为了能够对机电一体化和模拟技术有一个更好的纵览，我们首先简单学习了
相关方面的基础知识。
其次，我们简单的了解了 BroSAnT，博泽机电一体化开发仿真解决方案。之
所以需要了解 BroSAnT，是因为它是在所建模型的最终受用者。
第三，使用 MAST 模拟语言开发交叉臂机件模型，开发的过程主要是由三个
步骤来完成的。第一步，我们先仔细的研究了交叉臂机件的原理，并且将该结构
抽象成为钟表指针。如此，我们开发了第一版的模型。在第二步中，模型被改写
的能够包含更多的建造参数，不过，此时的模型仍然停留在一维的运动状态。在
第三版的模型中，从一维运动到二维运动的转变使得模型能够涵括所有的参数。
在第三版模型的基础上，一些实际因素，如弹性和摩擦，都被考虑，从而使得交
叉臂机件模型越来越经得起考验。
最终， 交叉臂机件模型和 BroSAnT 其它组件集成在一起，来测试模型在整
个车门系统中的功能。从 BroSAnT 测试结果表明，该模型达到了论文预期的要
求。与现实的测试数据比较，产生的误差在可接受的范围正在显示其有能力完成
以应用为目的的日常模拟任务。

ABSTRACT
Brose, with more than 100 years history, is a leading supplier in automotive industry. It
has a wide range of products serving for different purpose. But, one thing in common is
that its products are all mechatronic devices. As the development of mechatronics, more
and more development approaches are invented. Simulation, as a creative method in
mechatronic development, is drawing more and more attention. Brose makes use of
simulation with its platform, BroSAnT, Brose Simulation Analysis Tool. And the quality
of the simulation result is heavily depending on the quality of the simulation model,
which leads to the origin of the thesis. The model of cross-arm window regulator is
needed to enrich the components library. The work of the thesis is mainly divided into
the following several parts.
Firstly, general knowledge of mechatronics and simulation is studied for the purpose to
grasp an overview of the field.
Secondly, BroSAnT, the simulation solution of mechatronic development in Brose, is
shortly introduced, because it is the final utilizer of the model to be developed.
Thirdly, the model of cross-arm mechanics is developed in simulation language of
MAST through a process of three steps. In the first step, the principle of cross-arm
mechanics is carefully studied and the structure is abstracted into hour hand. And it
results into the first model. In the second step, the model is programmed to be able to
contain more construction parameters, but the movement of the model is still within one
dimension. In the third model, the transformation from one dimension into two
dimensions makes the model capable to cover all construction parameters. On the basis
of the third model, practical factors, like elasticity and friction, are considered, which
make the model of cross-arm mechanics even more robust.
In the end, the model of cross-arm mechanics is assembled together with other
components in BroSAnT to test its functionality in the complete door system. The test
result from BroSAnT proves that the model meets the requirement set for the thesis. Its
comparison with reality being in acceptable range shows its capability to fulfill
simulation for application purpose.

Chapter 1 Introduction
§1.1 Overview of Brose
Brose, the world leading supplier in automotive industry, has been contributing itself
dedicatedly to let people live an easier and easier life, since it was firstly established
more than 100 years ago. Nowadays, people are surprised not only by its persistence of
its long-history tradition, but also by its continuous progress and unlimited vitality.
However, Brosers are not shocked by its achievement, because Brose carves out its way
by adapting its management strategy to the trend of new century, maintaining the
outstanding quality of its products and reinforcing its capability of innovation.
Starting from 1908, Brose, a family-owned enterprise, has experienced over 100 years
of rise and fall of automobile industry. Today, the Brose Group is the eighth-largest
family-owned automotive supplier in Germany. There are 9,000 employees working for
the company at almost 40 locations in 19 countries.
Figure 1-1: Turnover of Brose
Due to the reliable product quality and competitive price, Brose maintains good
relationship of cooperation with more than 40 vehicle manufacturers. Not only the
market is growing and the customers are expanding, but also the innovation of
technologies and products is projecting a promising future of Brose. More and more
products, which are meeting the requirement of reducing the consumption of energy and

emission of CO2, are researched, developed and produced. The products of Brose
satisfy users with outstanding reliability and quality, as well as the consideration not to
damage the environment which belongs to our offspring. And the following will let you
have a glance over the products of Brose.
§1.2 Products of Brose
Brose is the world leading supplier of mechatronic systems and electric drives for
vehicle body and interior. It covers a wide range of products, as shown in the figure.
Figure 1-2: Products of Brose
§1.2.1 Door system
Brose develops and produces essential products for vehicle door, as shown in figure 1-3,
ranging from complete door system to the separated components of a door system, like
door frame, door plate, window regulators, latches, drives and electronics, making it
possible to offer the customers the right product solution.

§1.2.3 Electronic motors and drives
The Brose products family is enriched, after the acquisition of Siemens VDO. It
enhances the capacity of Brose to produce from cooling fan, air gate and to the motors
in car climate system and motors for the driving convenience, shown in figure 1-5.

§1.3 Mechatronics and summary
Brose produces a wide range of products to equip modern vehicles. These products have
distinct properties and work in different function areas. However, there is one thing in
common among all of them, which is, they are all mechatronic components. The
advantages of utilizing mechatronic parts over the pure mechanic parts are obvious. The
drives, or so-called actuators, make it easier for users to operate the mechanics, for
example saving human power. Furthermore, the intelligent control mechanism and
software increase the feeling of satisfaction and decrease the risk of injuries in case of
accidence. In the following chapter, we will have a glance over the history of
mechatronics and the approach to develop mechatronic components.

Chapter 2 Mechatronics and Simulation
§2.1 Mechatronic
Nowadays, mechatronic components are widely used in most fields, especially the field
of automobiles. Even if people are not noticing the convenience leading from
mechatronics, they are very happy with the result of being safer and more reliable. The
products of Brose are very good demonstration. The mechanical structures, driven by
electronic actuators and controlled by intelligent software, are the favorable products
solutions for customers, end users and environment. However, the research,
development and production of such systems are not done by a group of engineers from
Mechatronics[1]. In Brose, engineers from different fields like mechanics, electronics
and computer sciences, work together to integrate various functions into mechatronic
components. It makes mechatronics quite unique from the classical division of science
fields. Such characteristic can be called, cross field or multi domains.
The term of Mechatronics is a combination of ‘Mecha’ from Mechanics and ‘Tronics’
from Electronics. However, its domain has been keeping extending wider and wider
since it was firstly created 40 years ago, while its definition evolves from time to time.
Until today, it has not been determined yet. Nevertheless, as time goes, scientist and
engineers understand deeper and deeper the meaning of Mechatronics in their daily
research and development of real applications.
§2.1.1 Definition of Mechatronics
The definition of Mechatronics has been developed since the creation by the Yasakawa
Electric Company. Yasakawa defined Mechatronics in this way[6] [7]:
The word, Mechatronics, is composed of “Mecha” from mechanism and the “tronics”
from electronics. In other words, technologies and developed products will be
incorporating electronics more and more into mechanisms, intimately and organically,
and making it impossible to tell where one ends and the other begins.
An industrial robot is a prime example of mechatronic system; it includes aspects of
electronics, mechanics and computing.
Chapter 2 Mechatronic devices and simulation technology

The definition continued to evolve. One often quoted definition of mechatronics was
given by Harashima, Tomizuka, and Fukada [8]. In their words,
Mechatronics is defined as the synergistic integration of mechanical engineering, with
electronics and intelligent computer control in the design and manufacturing of
industrial products and processes.
Figure 2-1: definition of Mechatronics
§2.1.2 Development history
Beginning from 1969, when the term of Mechatronics was firstly created by Yasakawa,
until mid-1980s, Mechatronics didn’t draw much attention from both of academics and
industrial applications. Just a small group of researchers were studying it as well as
Yasakawa and its engineers. Resulting from the more and more need of reliable and
cost-efficient products, more and more engineers released the advancement of
mechatronic component and began the implication after late-1980s. At that time,
people’s understanding of mechatronics was still staying on the stage that mechatronics
is just a mixture of several different technologies. [7]
However, it is evident, that mechatronics is not just a simple combination of mechanics
and electronics, or call electro-mechanics. It keeps expanding its range by absorbing
new technologies so as to develop more and more complicated system. Almost every
kinds of symbolizing technology in its times involved in the development of mechanics
and the expending of its definition, as mechatronics evolves. Furthermore, the
