介绍了一种新的气门—气门应强化磨损模拟试验机及其相应的试验方法，该试验机采用了近似模拟工况的原理且试验时各因素（温度、腐蚀气氛、加载力和加载频率等）独立可控和数据自动采集。基于材料磨损机理，讨论了气门—气门应强化磨损模拟方法设计准则及主要参数对试验结果的影响。试验与实际发动机中气门磨损形态的一致性表明：文中所介绍的试验机及相应的试验方法可有效地对发动机气门—气门应进行快速强化磨损试验。由于试样采用产品样品，因此，试验评价结果可直接应用在工程中。
This paper introduces a new valve-door wear testing machine and its corresponding test method. The test machine adopts the principle of approximate simulation working conditions and the factors (temperature, corrosion atmosphere, loading force and loading frequency etc.) ) Independent controllable and automatic data collection. Based on the material wear mechanism, the influence of the design criteria and the main parameters of the simulation method for valve-valve wear on the test results is discussed. The consistency of the valve wear pattern between the test and the actual engine shows that the testing machine and the corresponding test method introduced in the paper can effectively test the engine valve-valve rapidly and rapidly. As the sample using product samples, therefore, test evaluation results can be directly applied to the project.
