摘要
介绍一种专门用于滑动摩擦磨损的试验机,它是一种具有高效、在线监控、实时数据显示、并能对多种尺寸试件进行试验的精密试验机。其中机架是该试验机的重要组成部分,在机架上安装有加载装置和传感器检测装置,试验机在运转过程中产生的振动对试验结果和试验数据的影响不容忽视,所以对机架进行动力学研究是十分必要的。利用参数化的FEA前处理软件TRUEGRID对模型进行全六面体网格划分,然后导入ANSYS中进行模态分析,得到系统的固有频率和振型,为改进试验机的性能提供数据支持。
The test machine specializing in sliding frictional wear was developed by tribology test laboratory of Yanshan University. It is a precise test machine which is real-time data processing, highly-activity processing and on-line control. The loading device is installed on the frame. The frame of testing machine is very important. Oscillating of test machine in operation is obvious and it is also a disadvantage factor for experiment. The model analysis of frame of test machine is necessary, the mesh division of model is done by software of Truegrid, and the analysis of modal is done by software of Ansys. The result of test is helpful to the developing of test machine.
