摘要
以南京农业大学宁远车队方程式赛车为对象,对悬架系统的设计优化分析进行概述,并重点说明利用ANSYS静力学分析模块对悬架零件的分析。利用CAD软件进行悬架系统的初步定点,用三维建模软件CATIA构建线框并对零件建模,对该套悬架系统进行受力计算并转化为零件受力。运用有限元分析软件ANSYS对其进行静态强度分析、疲劳分析以及运动学模态分析,分析该悬架系统零件在多种工况下的应力和形变,极限工况下的疲劳参数、寿命、安全系数以及不同阶数的固有频率和振型。验证该悬架零件设计的合理性,从而确保赛车能够安全参赛。
This paper, taking the formula car of Nanjing Agricultural University＇s Ningyuan racing team as the research object, outlines the main contents about how to design, optimize, and analyze the suspension system. Meanwhile, it explains emphatically how to use the static analysis module of ANSYS Software to analyze suspension parts. First, using the AUTOCAD software to de- termine the location of the point of the suspension system, and using the CATIA software to construct line box and model. Then, through knowledge of theoretical mechanics, the force of the suspension system was calculated and converted to the parts of the force. Using the ANASYS software, the static strength analysis, fatigue analysis, and kinematic simulation analysis were also done. Finally, the stress and deformation under various operating conditions, and fatigue parameter, fatigue life and safety factor under extreme conditions were analyzed. Natural frequency and mode shapes on different Rank Number were also analyzed. It＇s sure eventually that the racing can take part in the competition by verifying the rationality of the design of the suspension parts.
