The high-speed motion actuator is a high energy density actuator featured with instantaneousness, high speed, high acceleration, etc. Due to its special requirements, strict product tests should be carried out, especially concerning its reliability under loading. Traditional electro-hydraulic and electric servo load simulator used with the high speed motion actuator will produce an extraneous force/torque which is difficult to eliminate. This study focuses on the establishment of a new test system. It proposes a pneumatic servo loading method to reduce the extraneous force/torque. First, modeling and simulation of pneumatic servo loading are carried out in order to verify the rationale of the method and optimize the system parameters. Secondly, a laboratory bench is built, and load spectrum loading experiments are performed in different work conditions. The experimental results demonstrate that the pneumatic servo loading system can apply a variety of dynamic loads to the high-speed motion actuator with high accuracy and repeatability. These features are significant when the loading system is used in the test of high-speed motion actuators.
