1. Purpose and characteristics:
PMW series electro-hydraulic pulsation fatigue testing machine is mainly used for static compression test and dynamic unidirectional testing of various large parts: such as bridges, trusses, automobile chassis, front and rear axles, locomotive frames, chassis and various concrete structures The pulsation fatigue test is widely used in automobiles, scientific research, quality inspection institutions and other units.
PMW series electro-hydraulic pulsation fatigue testing machine adopts a unique crank connecting rod swing rod mechanism to realize the pulsating sine wave loading of the test piece, and adopts the best energy-saving design, which is one twentieth of the energy consumption of traditional fatigue equipment! There are various specifications of actuators (25 kN, 50 kN, 100 kN, 250 kN, 500 kN, 1000 kN, 2000 kN) to choose from. All actuators are shipped after a comprehensive performance test or ordered separately Users to complete complex experiments with multiple co-locations (multiple measurement points).
