The described device presents a cheap improved system for routine impact tests. The impacts are simulated by cart accelerations. The necessary energy is accumulated in rubber ropes. The required shape of acceleration curve is achieved with replaceable cams. The reactive acceleration force moves the drive system in the opposite direction on the base, which is shaped as an inverted box. Its walls are sealed in contact with the floor. The inner space of the 'box' is empty. Therefore, the total 'weight' increases. The recoil is limited by springs and hydraulic shock absorbers. For easy replacement of the device in the test room area the lifting function of the exhauster and several small wheels with level adjustment can be used. (Author/publisher)
