1. Purpose:
The PWS-15 type electro-hydraulic servo shock absorber comprehensive performance testing machine is mainly used for comprehensive performance testing of various automobile and motorcycle shock absorbers, such as indicator test, speed characteristic test, fatigue test, etc. The test method meets the relevant requirements of QC/T545-1999 "Automobile Tube Shock Absorber Bench Test Method", QC/T62-2007 "Motorcycle and Moped Shock Absorber Technical Conditions and Test Methods" and other standards. It can also be used for the temperature characteristic test of automobile shock absorbers (need to be equipped with an environmental test box). Optional 15kN, 20kN, 25kN, 30kN, 50kN, etc.
