针对目前国内对限矩型液力偶合器特性测试采用静态逐点方法与动态连续测试法存在不同的看法,介绍这两种测试法的原理及测试要点,并从理论上分析测试结果,从而明确前者的曲线表示液力偶合器固有的特性,是考核其性能最准确的方法;后者是很有工业价值的实用方法。它们各有优缺点,应以后者为前者的补充。 In view of the current domestic limit torque type hydraulic coupling test using static point-by-point method and dynamic continuous test there is a different view, introduce the principles and test points of the two test methods, and test results from the theoretical analysis to clarify The former curve represents the inherent characteristics of the fluid coupling is the most accurate way to assess its performance; the latter is a practical method of great industrial value. Each has its advantages and disadvantages, and the latter should be complemented by the former.
