摘要
为提高某型号装载机发动机悬置系统隔振性能,对悬置系统进行固有频率的优化配置并对其解耦率进行优化布置。以悬置静刚度和安装位置为优化参数,对悬置系统固有频率和解耦率进行优化匹配。结果表明,优化后悬置系统各阶固有频率分配更加合理,各方向解耦率得到显著提高,实车测试验证了悬置系统的隔振性能得到大幅度改善。
The frequency and decoupling ratio of a loader＇s powertrain mounting system are optimized in order to improve its isolation performance. The mount stiffness and position are selected as design variables. The results show that optimal frequencies are more rational,and the optimal decoupling ratios are increased significantly. Experimental results show that vibration isolation performance of the powertrain mounting system is significantly improved.
