Fluid Power Helps Simulation Table Push Performance Boundaries

摘要

The process of redesigning a simulation table for vibrational analysis with six degrees of freedom for 200 Hz performance required a mix of optimizations to its mechanical design and operation of hydraulic valves. But for Moog Inc. Test Systems, the keys came down to engineering fundamentals: reducing the moving mass and stiffening the system using fixed actuators and hydrostatic ball joints, along with selecting fluid power components that balanced flow requirements with inertia and step-response delays.
