The Mechanical Structure Design of Automobile Telescopic Shock Absorbers’ Double Acting Fatigue Tester

Abstract
 In recent years, with the rapid development of economy and automotive industry, there is a growing pursuit of the vehicle comfort and safety. Damper motor vehicles of various key components, its performance has a direct relationship to the vehicle's safety and comfort. Improve damper performance, ensure quality, in addition to advanced production technology, modern management methods, but also the quality of advanced detection methods. Born of the shock absorber test stand.
 The tests of the factory shock absorber Shock Absorber performance test is one important test, which tests the accuracy of the measured data directly related to the shock absorber performance. Necessary, and comprehensive consideration of quality, efficiency and safety of practicality, and strive to design a simple, reliable, low cost, high efficiency, simple operation, easy maintenance car shock absorber double-action Endurance Test.
 This article describes the current domestic and international research test bed absorber and shock absorber of the various test methods. At the same time, through the double-acting telescopic shock absorbers the main components Endurance Test structure design, theoretical design calculations, strength check, working principle and performance analysis, a detailed description of the program, the main research vehicle cylinder vibration Dual Dynamic Endurance Test machine operation mechanism, structure and stability. On this basis, to the shock absorber test rig of the prospect.
