考虑隔振性能的动力总成悬置系统多目标优化

某工程机械动力总成悬置系统能量分布比较合理但隔振效果不理想，为此在ADAMS软件中，以系统能量解耦和振动传递率最小为优化目标，对悬置系统模型进行仿真，得到动力总成悬置系统优化悬置参数。对优化前后的悬置元件进行多工况隔振测试。分析和测试结果表明，优化后悬置系统能量解耦程度和隔振性能均达到满意效果。

Multi-objective Optimization of Powertrain Mount System Based on Vibration Isolation

It is found that the powertrain mount system of an engineering machine has a reasonable energy distribution, but its vibration isolation effect is not good. To solve the problem, the powertrain mount system is optimized with the energy decoupling and the minimum vibration transmission rate as the optimization objectives. The powertrain mount system is simulated by means of ADAMS software and some optimization parameters are obtained. Then, the vibration isolation test under different working conditions of the system is performed. Results of the analysis and test show that both the energy decoupling and the vibration isolation performance of the powertrain mount system are satisfactory after the optimization.
