The system provides fatigue testing capabilities for axial, bending and torsion load. The vibration system is designed as a three-mas

6、s-system. In order to vary the testing frequency additional masses are available. The dynamic drive is done by an unbalanced mass drive which drives the flexible SPRING ACTION system. The controlled static load is introduced by a gear motor which drives a ball screw spindle. The static drive unit is

7、 mounted beneath the mounting table and offers adjustable limit switches. In the set up mode the static drive unit can be operated with a manual control. The force value can be displayed on the display of the control unit. The test system can be used force, displacement or strain controlled.The test
