In order to study the dynamic output displacement of the actuator in the time domain, a new M-EHA design method is proposed and a principle prototype is developed. In order to meet the relevant requirements involved in the actuator test process, the relevant structures of the actuator were optimized and the experimental platform was set up; a new type of reed valve cavity structure was proposed to effectively improve the performance of the entire valve. A ball stud prestressing device was designed, which not only protects the drive unit, but also can test the output performance of M-EHA under different prestresses; the output displacement characteristics of M-EHA were experimentally studied under different operating frequencies, and the output speed characteristics of the actuator were experimentally studied under different bias pressures.
