摘要
发动机作为高空作业平台振动的主要激励源,对高空作业时的平稳性、安全性有很大影响。性能良好的悬置系统能有效的隔离发动机的激励振动,切断振动向车架、车身的传递路径。良好的悬置匹配还能起到整车减振降噪的作用,提高作业平台的平稳性、安全性。本文采用Adams软件建立了发动机悬置系统的六自由度动力学仿真模型,将Adams/View与Adams/Vibration模块联合,对原动力系统进行了模态仿真分析。同时在发动机测试台架各悬置点上布置振动加速度传感器,进行模态试验,检测动力总成的实际振动情况。最后,将Adams动力学仿真结果与刚体模态试验结果进行对比,分析验证了所建虚拟样机模型的合理性。
In this paper, a dynamic simulation model of six degrees of freedom for engine mount system is established by using of Adams software. Combined with Adams/View and Adams/Vibration module, modal simulation analysis of the original engine system was carried out. At the same time, a vibration acceleration sensor is arranged on each suspension point of the engine test bench for modal test to detect the actual vibration of the power assembly. Then compared with the ADAMS dynamics simulation results and verify that the virtual prototype model building is reasonable.
