Abstract : The report covers a series of experimental tests to determine the effect of cylinder and servovalve design on the magnitude of acceleration noise and hydraulic bump in simulator electrohydraulic controls. It includes tests on systems comparing equal with unequal area cylinders and high gain with low gain servovalves. The results indicate significant benefits with equal area cylinders and low gain servovalves. (Author)
