摘　　要：为优化压路机钢轮振动噪声,选择同吨位的圆周振动型和垂直振动型压路机,以压路机钢轮为研究对象,通过有限元软件和Virtual.Lab Acoustics软件进行钢轮的振动噪声联合仿真,并利用LMS Test.Lab测试系统对振动压路机进行实车测试,验证仿真有限元模型和边界元模型的准确性。仿真结果与实测结果均表明,垂直振动压路机钢轮的机外噪声大大低于圆周振动钢轮,可为未来振动压路机NVH高性能产品的设计提供指导方向。To optimize the vibration noise of the steel drum of the roller,the circumferential vibratory roller and vertical vibratory roller of the same tonnage are selected,and the steel drum of the roller is taken as the research object.The finite element software and software Virtual.Lab Acoustics are used for co-simulation of the vibration noise of the stee drum,and LMS Test.Lab test system is used for real vehicle test of the vibratory roller to verify the accuracy of thesimulation finite element model and boundary element model.The simulation results and the test results both show that the external noise of the steel drum of the vertical vibratory roller is much lower than that of the steel drum of the circumferential vibratory roller,which provides a guiding direction for the design of high NVH performance products offuture vibratory rollers.
