Abstract

The approach to forecasting accelerated modes for faster testing of friction pairs having solid lubricant coatings using computer simulation is examined. Load and temperature test modes under which acceleration leads to faster testing were defined. Loads and temperatures have been revealed that determine the multiple transition from predominantly elastic and elastoplastic deformation of solid lubricant coatings to a predominantly elastoplastic and plastic one, which characterizes the maximum performance of high-resource friction pairs with solid lubricant coatings. Comparison of the results of the full-scale experiment and numerical experiments confirmed the correctness of the proposed method. It is shown that the ratio of elastoplastic contacting to all contacting protrusions determines the conditions under which the forcing of the modes leads to accelerated testing.

加速模式的计算机模拟，以更快地测试具有固体润滑剂涂层的摩擦副

摘要

检验了预测加速模式的方法，以便使用计算机模拟更快地测试具有固体润滑剂涂层的摩擦副。定义了载荷和温度测试模式，在这些模式下，加速度导致更快的测试。已经揭示了载荷和温度，这些载荷和温度决定了从固体润滑剂涂层的主要弹性和弹塑性变形到主要是弹塑性塑料的多重转变，这表征了具有固体润滑剂涂层的高资源摩擦副的最大性能。全面实验和数值实验结果的比较证实了该方法的正确性。
