Automobile shock absorber welded junction fatigue testing machine

Specifications Large scaled test system for bogie frames such Locomotives, Metros, Railbus)

Main purpose: shock absorber welded junction fatigue testing machine adopt actuation overhead, ascend and descend by hydraulic and locking, mainly used to fatigue test on automobile welded junction, such like shock absorber. Main technical data: Max static loading capacity: +/- 20kN, dynamic loading capacity:+/-16Kn Testing force accuracy: +/-1% of show value, measuring range decrease 1step and 5 step, starts from reach 20% full rang. Actuation max displacement +/-50mm(stroke 100mm) Displacement accuracy: after reach 1% of full range, decrease by 1 step and 5 step Loading frequency: 0.01-50HZ(sine wave), can be do with sine wave, triangular wave, square wave,oblique wave Grips space: 50-600mm
