1、附 錄The Spin Tester for the Automobile Clutch Test with High Speed Photography SystemAbstract:The development of a new type spin tester for the automobile clutch test is introduced.A vertical flexible shaft system with

2、 rubber damper is applied to the tester.The crushing test of the clutch assembly can be done frequently on the spin tester,and the high speed photography system adopting ordinary camera can record the crushing wink.The c

3、rushing test of a clutch on this tester is also introduced.and the weak link of the clutch assembly can be found from the photograph of crushing wink.Key words:spin tester automobile clutch high speed photographyClutch b
