摘要

本文对履带急救车非线性减振系统进行结构优化研究,目的是使其减振性能得到进一步提高,结构优化主要针对担架台进行。首先,在借鉴"动力吸振器"原理的基础上,提出了两种结构优化方案,分别为线性优化方案和非线性优化方案,通过对比研究确定线性优化方案为最终优化方案,并在冲击激励下对线性优化方案进行了验证。然后,采用Sobol法对结构优化后的减振系统进行全局灵敏度分析,获得了减振系统各参数的重要性排序。最后,采用NSGA-II对结构优化后的减振系统进行参数优化。以上研究使履带急救车非线性减振系统的性能得到了明显改善,这对于提高急救车内伤病员的舒适性具有重要意义。
This paper aimed at improving the performance of nonlinear vibration reduction system of the tracked ambulance by the structure optimization design. The structure optimization focused on the stretcher base. Two structure optimization schemes were proposed based on the mechanism of dynamic vibration absorber,namely,the linear and nonlinear structure optimization schemes. The linear structure optimization scheme was finally adopted by comparison of two schemes under random vibration,and the performance of linear scheme was also validated under shock vibration. Then the Sobol method was used to study the global parameter sensitivity of nonlinear vibration reduction system after structure optimization. At last,the NSGA-II was used to optimize the performance of nonlinear vibration reduction system after structure optimization. The performance of nonlinear vibration reduction system of the tracked ambulance was improved greatly after above studies. This was of great significance to improve the ride comfort of the sick and wounded in the tracked ambulance.
