【摘要】：目前,汽车设计领域尤其是乘用车设计领域关于车身侧倾方面的研究已经不少,但对商用车特别是轻型载货汽车(比如厢式运输车)侧倾的相关研究和指导实际工程开发的方法,并不多见。目前中国商用车市场,轻型载货汽车有着巨大的保有量,应用领域非常广泛,实际的使用状况也非常复杂,由车身侧倾带来的干涉问题很有必要深入研究。本文分析了整车侧倾相关参数设计的传统理论及现状,系统阐述了整车侧倾的基本原理,并对现有设计方法进行了初步研究;对存在车架和车轮的干涉问题的某在产车型进行了实际参数分析,建立了该车的三维仿真模型,应用计算机动力学仿真软件,对整车侧倾性能进行了仿真分析,推测出了实车存在的风险;从优化结构参数上提出了有效的解决措施,通过进一步的仿真和优化以及试验验证,实车存在的车架和车轮的干涉问题得到了解决;最后,对企业现有的设计方法得出的结果进行了验证和对比,指出了现有方法优缺点,对相关参数的取值提出了简单实用的方法。本研究结果为后续设计总结了实用的方法,该方法可以指导高质量、高效率的完成整车侧倾相关参数的设计。
[Abstract]:At present, there have been a lot of researches in the field of automobile design, especially in the field of passenger car design. However, it is rare to study and guide the practical engineering development of commercial vehicles, especially light cargo vehicles (such as van transport vehicles). At present, China's commercial vehicle market. Light cargo vehicles have a large number of applications in a wide range of areas, the actual use of the situation is also very complex. It is necessary to study the interference problem caused by the body roll. This paper analyzes the traditional theory and current situation of the whole vehicle roll related parameter design, and expounds the basic principle of the whole vehicle roll. The existing design methods are studied preliminarily. The actual parameters of an in-production vehicle model with interference of frame and wheel are analyzed, the three-dimensional simulation model of the vehicle is established, and the roll performance of the whole vehicle is simulated and analyzed by using the computer dynamics simulation software. The risk of real vehicle is inferred. The effective measures are put forward from the aspect of optimizing structural parameters. Through further simulation and optimization as well as experimental verification, the interference problem of frame and wheel in real vehicle is solved. Finally, the results of the existing design methods are verified and compared, and the advantages and disadvantages of the existing methods are pointed out. This paper presents a simple and practical method to determine the values of the related parameters. The results of this study summarize the practical methods for the subsequent design. This method can guide the design of the whole vehicle roll related parameters with high quality and high efficiency.
