在发动机研制过程中,必须用发动机台架强化试验来模拟汽车在实际使用中的苛刻条件,考核它的可靠性和耐用程度。文中介绍了台架强化试验的强化参数和国内外某些零部件及整机综合台架强化试验规范,强调了应根据各制造厂家的情况和不同用途的发动机制订正确的试验规范和方法。 In the engine development process, you must use the engine bench to strengthen the test to simulate the car in the harsh conditions of actual use, assess its reliability and durability. This paper introduces the strengthening parameters of bench strengthening test and some domestic and foreign parts and components as well as the comprehensive bench strengthening test specification, emphasizing that the correct test norms and methods should be formulated according to the situation of each manufacturer and the engine for different purposes.
