一些关于车辆动力性能的文章！

freebobo

这是本人在做论文期间找到的一些文章，主要关于车辆的动力学特性，尤其是轮胎力学特性方面的文章，希望对大家能够有所帮助！当然，也希望版主酌情加分，呵呵。。。

车辆动力学方面的一篇文章，主要介绍在进行游戏设计中赛车的动力学特性。个人认为虽然较简单但比较全面。下面是摘要：
Vehicle dynamics is concerned with the movement of vehicles. In general, the
movements of interest are braking, acceleration, and cornering. The forces imposed on the
vehicle bythe tires, gravity, and aerodynamics determine its behavior during these conditions.
The vehicle and its components are studied to determine the vehicle’s response to the forces
produced during operation. This paper discusses methods that can be used todevelop a
realistic vehicle dynamics model for use in a racing simulation.

希望对大家有用！

这是一篇项目报告，主要关于主动防扭杆对提高车辆操纵稳定性和安全性的作用，特别是减少车辆重心提高后操纵稳定性和安全性的隐患。下面是摘要部分，有兴趣的可以下来看看！后面还附有matlab和simulink的程序和框图！
In the United States there is a growing trend towards larger vehicles, even when a much smaller vehicle will suffice, leading to an increase in the average vehicle mass center height.  Some drivers have also associated the increased vehicle size with increased safety, leading to more aggressive driving behaviors.  In addition, consumers are often exposed to misleading commercials concerning the capabilities of Sport Utility Vehicles (SUV’s).  These factors, among others, have increased the number of roll over occurrences, especially in SUV’s.  For this project, we have elected to model, design and control an active roll bar.  

        Roll bars are devices used to reduce load transfer during aggressive cornering/turning maneuvers, and thus reducing roll, improving handling characteristics and safety.  Our active roll over prevention system improves on this by actively adjusting the rolling stiffness of the vehicle.  For our simulations, we started with a modified Yaw/Roll Vehicle Model, using our roll bar actuator as the input.  Other system modeling highlights include the Magic Tire Formula, and the MacAdam Driver Model for road following.

Tire Models for Use in Braking Applications项目报告，主要介绍了轮胎的发展历史，轮胎的力学和动力学特性，个人认为比较好，下面是摘要的摘要：

The introduction is followed by a section explaining the basic con-
cepts used in the thesis. The mechanic and dynamic properties of a tire
are briefly discussed and the notation, important for futher reading is
introduced. Chapter 3 presents several ways to express the force-slip
relation and two different approaches to explain this behavior physi-
cally are discussed. The last part of the chapter describes methods to
derive the tire characteristics for cases of simultaneous braking and
cornering using tire data from pure slip measurements. A new method
based on physical modeling is presented. Factors that affects the tire
modeling are discussed in Chapter 4. Here also methods to make the
brush tire model more accurate and flexible by use of a calibration
factors are presented. The final chapter discusses the validity of the
brush model and compares it to measurements performed on a real
vehicle.

继续，这是一本书的第一章，主要关于轮胎的力学特性。个人认为深入浅出，对于了解轮胎力学特性非常有帮助。

Construction ofNovel Semi-EmpiricalTire Models for CombinedBraking and Cornering这是Tire Models for Use in Braking Applications同一个作者Jacob Svendenius写的。如果大家想要做一些关于轮胎动力学特性和轮胎刷子模型的东西，我想这会是非常好的资料！
