Abstract A simulation model to determine dry sliding wear behavior of wastegate bearings is validated by comparison with experimental results. The wear results of a pin-on-plate tribometer running at 300 ∘ C are used to define global wear coefficients. These serve as input information for a FEM simulation which is able to calculate local wear progress in the model. The simulation results show good correlation with the experiment for the general wear shape and the local wear depth. Volume gain is observed on one of the contact partners due to material transfer. This effect is not included in the simulation model and thus cannot be reproduced.

汽车涡轮增压器废气门轴承干滑动磨损模拟方法的验证

摘要 通过与实验结果的比较，验证了确定废气门轴承干滑动磨损行为的仿真模型。在 300 ∘ C 下运行的销钉式摩擦计的磨损结果用于定义整体磨损系数。这些作为 FEM 模拟的输入信息，能够计算模型中的局部磨损进程。模拟结果表明，一般磨损形状和局部磨损深度与实验具有良好的相关性。由于材料转移，在接触伙伴之一上观察到体积增加。这种效果不包含在模拟模型中，因此无法重现。
