The Test Rig for Automobile Sway Bars of WPM is mainly used with dynamic fatigue tests of automobile sway bars. Features The testing rig consists of the following functional modules: - Clamping foundation as base plate (made out of special cast iron with steel additive, vibration-isolated) - Load generator designed as a chain (2 hydraulic testing cylinders with integrated displacements sensor, servo valve and hydraulic fluid storage, can be adjusted in transverse direction) - Power generator (hydraulic power pack with housing), especially developed for demands of servo-hydraulic testing - Control system, including software - Specimen clamping and Adaption - 2 stabilizers can be tested at the same time with special adaptations Clamping foundation (base plate) The base plate bears the test frame and the specimens. Its dimensions are to be selected the way that future upgrades can be added to the base plate. The base plate is made of cast iron with steel additive. Lengthwise, 14 T-slots according to DIN 650 – 22H12 for screws M 20 (300 mm distance) are applied. Using appropriate T-slot nuts according to DIN 508 - M20, various structures can be realized. These T-slot nuts are pushed into the T-slots of the clamping plate at the desired position. In order to ensure the highest possible stability of the plate, a special casting process is used, guaran-teeing the greatest possible stress-relieved casting. In addition, the ribs at the end are reinforced in a T-shaped way. The raw surfaces are blasted clean. The clamping plate is vibration-isolated and level-regulated by means of pneumatic bellow cylinders.
