摘要摩托车行业的发展使得摩托车车架性能要求的重要性更加明显。对于摩托车车架性能的测试也变得日益重要，国内外各个企业对车架疲劳的试验也展开了积极的研究。前悬架疲劳试验是对摩托车车架以减震器的耐久性的疲劳试验。通常可以通过道路试验来达到目的，但是道路试验费时费力，成本高。而台架疲劳试验机的出现就解决了这个问题。疲劳试验机可以在室内对不同型号的摩托车车架进行试验，方便有效，便于记录，节省成本。因此疲劳试验机的研究就更为重要。49098

Abstract

The development of the motorcycle industry makes the importance of the performance requirements of motorcycle frame more obvious .Performance test for the motorcycle frame has become increasingly important.The front suspension fatigue test the durability of the fatigue test the motorcycle frame to the shock absorber.A road test can usually achieve their goals, but road test is time-consuming and high cost.Bench fatigue testing machine to solve this problem . Different types of motorcycle frame can being tested in the room through fatigue testing machine, it is convenient and effective, easy to record and cost savings. So, fatigue testing machine is even more important .

In this paper, the design of the fatigue testing machine with a single rotating hub plus vibration detection of the front suspension and shock absorbers.Turn hub is installed on the rotating hub in order to simulate uneven road .Turn the wheel to rotate the drive and drive the structural design, sizing and strength checking. Adjust the position of the fixture, the transmission mode design .Using the cylinder to exert a lateral force on the frame, fixed and simulate the gravity of the driver. 

Key Words：Fatigue test;Strength Check;Transmission;Frame
