| 摘 要： | 基于磨合磨损的分形理论,结合粘着磨损理论和Majumdar-Bhushan分形接触模型,建立了换挡同步器接触磨损的数学模型.研究了AMT、DCT快速平稳换挡过程中换挡力对同步器磨损的影响,仿真结果表明.相对于低挡位,高挡位时同步时间短.所需要的换挡力小,所带来的同步齿环磨损深度率小;适当增大换挡力可缩短磨合时间和同步时间,减少同步器磨损量.

| Abstract: | Based on fractal theory of break-in wear,adhesive wear theory and fractal contact model Majumdar-Bhushan,a mathematical model of shifting synchronizer contact wear was established in this paper,and the influence of shifting force on synchronizer wear in the process of quick and steady shifting for AMT and DCT was also studied.The simulation results showed that the synchronization time was short;the shifting force was small,and the wear ratio of gears was small at high gears position;appropriate increase of ... |
