【Abstract】 This paper presents the basic principle of measuring the internal force of draw-cable under the random interferential force action and introduces the frequency domain method and the domain method which identify the inherent frequency of draw-cable and other correlative e problems. Both experimental and research results show that the dynamic test method measuring the internal force of draw-cable is simple and convenient and the results are reliable.更多还原
