摘要:第二届全国大学生工程训练综合能力大赛对参赛小车的运行轨迹有特殊要求,即小车在运行过程中能自行避障。为了满足此功能,在对小车结构进行简化的基础上,建立了小车轨迹的数学模型和方程。然后在Matlab/Simulink软件中建模进行仿真分析,在仿真结果的基础上对小车结构进行优化,同时获得小车在起点的关键数据,如起始角、起始坐标及起始速度等,为小车后续的制作和运行提供了理论基础。

Abstract:The car model in the second National Contest of engineering training for comprehensive abilities for college students is required to avoid obstacles by itself. The paper establishes the mathematical model and equation of the car track by simplifying the structure. The optimizes its structure on the base of a simulation in Matlab/Simulink software. The paper obtains key data, such as starting angle, starting coordinates and starting velocity etc, to provide theory for the fabrication and running of the car.
Key words:simulation;mathematical model;MATLAB/Simulink
