摘要
本文基于ANSYS软件对某轿车盘式制动器零部件进行模态仿真分析。首先将建立的盘式制动器零部件的三维模型导入Ansys-Workbench中;然后对模型进行网格划分,确保模型准确描述结构特征和边界条件;最后采用模态分析方法,对盘式制动器进行固有频率和振型分析。仿真结果表明,制动器主要零件的固有频率随模态阶数的增加呈递增趋势。并且,从第一阶模态开始,各部件的固有频率存在显著差异,表明制动盘和摩擦片的模型设计和材料选择较为合理,能够有效避免共振问题的产生,对于盘式制动器的设计和性能优化具有重要的指导意义,可为制动系统的安全和可靠性提供理论依据。
This article is based on ANSYS software to conduct modal simulation analysis of a certain car disc brake component. Firstly, import the 3D model of the disc brake components into Ansys Work-bench;Then mesh the model to ensure accurate description of structural features and boundary conditions;Finally, modal analysis method is used to analyze the natural frequency and vibration mode of the disc brake. The simulation results show that the natural frequencies of the main com-ponents of the brake show a decreasing trend with the increase of modal order. Moreover, starting from the first mode, there are significant differences in the natural frequencies of each component, indicating that the model design and material selection of the brake disc and friction plate are rea-sonable and can effectively avoid resonance problems. This has important guiding significance for the design and performance optimization of disc brakes, and can provide a theoretical basis for the safety and reliability of the braking system.
