When Piedrafita was working on the design of this new shock absorber product, the company needed a complex test system for the development phase and a robust fatigue testing system to ensure reliability. The company contacted Moog with the request to deliver a test system that could meet high performance specifications of 100 g acceleration peaks, 4.4 m/s velocity (14.4 ft/s), 80 kN (18 kip) impacts and more than 300 kW power transmission.
The solution that Moog delivered consists of a hydraulic servo actuator featuring 90 kN (20.2 kip) force at 280 bar (4,000 psi). The high dynamic and low friction actuator contains a Moog D792 3-stage Servo Valve with 1000 l/min (264 gpm) flow and internal vibration damped electronics. The solution also comprises a control cabinet with a Moog Portable Test Controller and software featuring special safety scripts.
