摘要:随着客车车辆向高速方向发展,机车车辆关键部位的可靠性已经成为了人们关心的问题。轮对是由车轴和车轮通过盈配合而成,机车车辆全部重量通过轮对施加在钢轨上,因此其在机车车辆的运行过程中起到了关键性的作用,轮对结构的性能直接影响机车车辆的运行安全性和可靠性。在研制高速客车时,应特别关注轮对的强度问题。因此,在设计阶段应对其进行完善的强度校核及必要的试验分析。基于此,本论文针对客车转向架轮对进行理论分析。传统经验设计和手工分析计算难以满足高性能列车轮对的设计要求。而通过有限元分析软件对轮对进行受力分析将大大的降低人力、财力,并使分析得出的数据结果更接近实际情况。本文将对高速客车轮对强度分析的发展研究现状进行介绍,并采用UG软件建模,以及Abaqus软件进行有限元分析试验并对车轮静强度进行了评定,使研究具有现实工程的实用价值。35672

The Structure Design and Finite Element Analysis of Passenger Wheelset at the Speed of 100km/h
Abstract:With the fast development of high speed passenger rolling stock, the reliability of key parts of the rolling stock has become the concern of the people. The wheel set is composed of axles and wheels by interference fit. The full weight of rolling stock is applied in rail through wheel set ,so it has played a key role in the operation safety and reliability of the rolling stock directly .In the development of high speed passenger rolling stock ,we should pay special attention to the strength problem of wheel set .Therefore, we should check the strength and do necessary test analysis at the design stage .Based on this ,the thesis focuses on the theoretical analysis of wheel set of passenger rolling stock bogie .The experience of the traditional design and analysis of manual calculation is difficult to meet the design requirements of high performance of train wheel set . Through the finite element analysis software to analyze the stress of wheel set will greatly reduce the manpower, financial resources, and makes the analysis results more close to the actual situation .This article will introduce the study on development status of strength analysis of high speed passenger rolling stock wheel set .Using UG for modeling ,ABAQUS for finite element analysis and test the static strength of wheel set ,which has practical engineering value.
