摘要 针对现有的台架测试方法存在测试时间长、人为因素影响大以及参数调整不灵活等问题,研究提出自动化测试优化方法,包括自动化测试、参数优化手段,基于有限元分析模拟制动过程,以优化摩擦副接触压力分布为例,验证优化方法有效性。研究表明,优化方法对制动盘的变量改变基本在10%以内,能有效控制制动盘变量,温升台测试均方差减少90%。其中最大接触压力位于制动活塞压缩处,接触压力分布显著改善,能够以最小变量实现最佳的优化效果。可见优化方法成功提高了测试方法的准确性和效率,并提供了有效的变量优化,也为制动盘性能评估提供了可靠的数据支持。 Aiming at the problems of long testing time,human factors,and inflexible parameter adjustment in existing bench testing methods,it proposes an automated testing optimization method,including automated testing and parameter optimization methods.Based on finite element analysis,the braking process is simulated,and the effectiveness of the optimization method is verified by optimizing the contact pressure distribution of friction pairs.The result showes that the optimization method can effectively control the variables of the brake disc within 10%,and the mean square error of the temperature rise table test is reduced by 90%.The maximum contact pressure is located at the compression point of the brake piston,and the distribution of contact pressure is significantly improved,which can achieve the best optimization effect with minimal variables.It is obvious that the optimization method successfully improves the accuracy and efficiency of the testing method,provides the effective variable optimization and more reliable data support for brake disc performance evaluation.
