Crank Operated Damper Performance Test System
The Crank Operated Damper Performance Test System is a mechanically driven test rig designed to evaluate the performance characteristics of automotive shock absorbers. The system uses a crankshaft-based electromechanical drive to apply a controlled, sinusoidal motion to the damper, replicating the loading conditions typically experienced during real-world vehicle operation.
It supports full-stroke dynamic testing of a wide range of dampers including mono-tube, twin-tube, hydraulic, and oil-gas types, with a displacement capacity of up to ±75 mm and operational frequencies up to 6 Hz. The system is equipped with load, displacement, and velocity sensors, providing real-time force-displacement and velocity measurements for damper evaluation. The bench-top design makes it suitable for use in R&D labs, QA departments, and academic institutions, where consistent and repeatable damper testing is required.
The system includes quick-change fixtures to accommodate different mounting types and damper geometries, making it compatible with 2, 3, and 4-wheeler suspension components. A built-in data acquisition system and user-friendly interface allow operators to monitor test parameters, configure stroke profiles, and export data for further analysis. It operates with minimal maintenance, requiring only standard electrical power and compressed air.
