High-Flow Catapult & Ejection Hydraulic Simulation Test Bench

When a load requires an instantaneous burst of force for ejection testing to verify its characteristics, an ejection test must be conducted, necessitating the application of either lateral or longitudinal ejection forces. An electrohydraulic servo system equipped with an accumulator bank capable of delivering high‑rate, transient flow is an excellent solution. Depending on the load’s requirements for magnitude and rate of applied force, the system can achieve precise flow control, enabling test conditions such as constant velocity, constant acceleration, and constant flow output. In this domain, the key to performance lies in the reliable, high‑speed provision and controlled distribution of stored energy; the integrated servo and local‑control technologies underscore Schwerll’s leading expertise in accumulator‑based flow‑control and distribution.

Schwerll achieves precise control of the test system through flow measurement, thereby attaining the experimental objectives.
