背景技术Background technique
摩擦系数的测试在工业上被广泛的应用，通过摩擦系数的测试能够检测工件的耐磨程度以及摩擦安全性能；过去的大载荷摩擦试验机（测量摩擦系数的装置），测量不同运动形式工况一般设计不同摩擦试验机，需要同时测试往复摩擦系数和摇摆摩擦系数时就得配备不同的摩擦系数测试机，成本高昂，并且分开测试导致测试效率低下，人工成本增加。The test of the coefficient of friction is widely used in industry. The test of the coefficient of friction can detect the wear resistance of the workpiece and the safety performance of friction; Generally, if different friction testing machines are designed, different friction coefficient testing machines must be equipped when testing reciprocating friction coefficient and swing friction coefficient at the same time. The cost is high, and separate testing leads to low testing efficiency and increased labor costs.
