起重机在实际的使用中,车轮和轨道之间会有很大程度的磨损,这就要求起重机车轮和轨道的承载能力和抗磨损能力要不断提高。本文利用SolidWorks软件对轨道列车常用的LMA、GDM以及S1002型三种车轮踏面进行再设计,通过软件建立车轮踏面与轨道的配合模型。通过ANSYS软件对三种踏面P60轨道不同的接触状态进行非线性接触分析;采用轮轨法相间隙法,利用Matlab软件对受力较好的踏面进行优化设计;最终对优化前后的车轮踏面进行接触应力以及性能分析,达到提高起重机车轮抗磨损的能力的目的。
Abstract:In actual use, the wear between the wheel and the track of the crane occurs frequently. Therefore, the bearing capacity and the wear resistance of the wheel and the rail are required to be further improved. In this paper, SolidWorks software is used to redesign LMA, GDM and S1002 treads which is commonly used in rail trains, and the nonlinear contact analysis on different contact states of P60 tracks of the three treads is carried out by using Ansys software. On the basis of the method of wheel-rail phase clearance optimization, the wheel tread in good load-bearing condition is optimized by using Matlab software; Finally, the analysis on the contact stress and performance of the wheel tread before and after optimization is performed to increase the wear resistance of the crane wheel.
