摘要
基于滚动轴承的动力学理论,建立了圆柱滚子轴承的非线性动力学微分方程组,使用希尔伯特-修斯-泰勒(Hilber-Hughes-Taylor,HHT)变步长积分算法对其动力学微分方程组进行对称多线程(Symmetricmulti-processing,SMP)并行求解,联合机械系统动力学自动分析软件ADAMS、控制仿真软件Matlab/Simulink搭建了圆柱滚子轴承的半物理仿真试验系统,实现了圆柱滚子轴承动力学仿真系统与物理试验机之间的信息交换,进而对滚动轴承的半物理仿真试验技术进行了探索与研究。该研究结果为滚动轴承的半物理仿真试验技术提供了一条可行的技术路线,能够对轴承的试验结果进行补充,为滚动轴承的半物理仿真试验技术提供借鉴与参考。
Based on the dynamics of rolling bearings, the nonlinear dynamic differential equations are built and solved by Hilber-Hughes-Taylor(HHT) integer algorithm with variable step in combination with symmetric multi-processing(SMP) parallel solving technology. And then, automatic dynamic analysis of mechanical systems(ADAMS) is used in conjunction with the control simulation software Matlab/Simulink to set up the hardware-in-the-loop simulation system, which can complete the communications between the dynamics simulation system of cylindrical roller bearing and the testing machine for cage’s dynamic performance. According to the study on the hardware-in-the-loop simulation technology, it shows that the technical route is feasible, and the results of hardware-in-the-loop simulation can be used to enrich the experimental results which can not be measured in the work process of testing machine. The relevant research would supply references on how to develop the hardware-in-the-loop simulation technology of rolling bearing.
