Abstract The wear of automotive chain drive systems after high mileages is numerically calculated based on Fleischer’s energetic wear equation. This equation is embedded in a FE-model, consisting of one single chain link only. Their time-variant positions and acting forces are taken from a multi-body simulation. A focus is on ensuring the quality of the FE-model and the contact between pin and bush, where here a penalty approach has provided a stable solution schema. The parameters of the wear model are derived from measurements. After each time increment the wear results in a changed surface geometry, which is used for the simulation of the next time increment. The enormous computation time is reduced by the development of a convenient extrapolation factor. The complex simulation approach is applied to the chain drive of a test vehicle after a mileage of about 50000 km. The comparison of the simulated and measured data demonstrates an agreeing correlation.

分析磨损模型及其在汽车衬套链传动系统磨损模拟中的应用

摘要 基于Fleischer的能量磨损方程，对汽车链传动系统在高里程后的磨损进行了数值计算。该方程嵌入在一个 FE 模型中，仅由一个链节组成。它们的时变位置和作用力取自多体模拟。重点是确保 FE 模型的质量以及销和衬套之间的接触，在这里惩罚方法提供了稳定的解决方案模式。磨损模型的参数来自测量值。每次增量后，磨损会导致表面几何形状发生变化，用于下一次增量的模拟。通过开发方便的外推因子，减少了巨大的计算时间。将复杂的仿真方法应用于测试车辆行驶约50000公里后的链传动。模拟数据和测量数据的比较表明了一致的相关性。
