CYCLIC FATIGUE TESTING MACHINE
with servo-pneumatic actuator
LiTeM series VDC-A (Vertical Double Column – Air) systems are modular table top fatigue testing machines complete with external frames and guards, equipped with a pneumatic actuator with a load range of 0 to 7 kN and stroke up to 1500 mm.
The VDC-A series is made of modular aluminium profile members and enables the actuator to be positioned in 2 directions for even greater versatility. The actuator is mounted on an horizontal strut with variable gap, thus allowing A63-A125 actuators to be used and providing a larger test area. There is also a version with a gantry structure which enables the actuator to be positioned manually in 3 directions.
VDC-A machines are the solution for manufacturers and research centres who want to optimise their design and development processes. This enables them to offer their clients excellent quality control and final testing, while reducing costs and without compromising the quality of their results.
The load is applied by special low wear pneumatic actuators with contactless deflection sensors integrated into the rod. This ensures that the sensor itself is completely unaffected by wear.
Each machine has a RTC9001-S standard controller, complete with RTC PN-STD software with Start Stop test and acquisition and display functions for the data coming from the load and displacement sensor or an auxiliary sensor.
