摘要
本文以多体系统动力学的理论方法为基础,利用机械系统仿真软件ADAMS/Car,建立了某校2011年FSAE整车虚拟样机,参照中国2011年FSAE大赛规则,进行了整车动力性及操纵稳定性等动力学仿真和评价。本文主要仿真分析了直线加速、常半径转弯等两个试验。分别研究了轮胎气压和直径在直线加速过程中对整车动力性能的影响及在常半径转弯试验中对整车操纵稳定性的影响。通过仿真分析找到了相关规律,为车队购买轮胎和参加实际的比赛提供了理论指导。
Based on the classic theory of multi-body system dynamics, a virtual prototype of the Formula SAE racing car is established under the ADAMS/Car, which is the most advanced mechanical system simulation software in the world. According to the competition rules in 2011, the simulation of vehicle controllability and stability test are run. This paper has mainly performed three tests including linear acceleration and constant radius cornering. Respectively tire pressure and diameter were researched to find out how they influence the vehicle power performance in the process of linear acceleration, and how they influence the controllability and stability performance in the process of constant radius cornering. It provides the theoretical guidance for the team to buy tires and attend the race through the conclusion of simulation
