Abstract
AbstractSolenoid actuator is the most important device for driving the precise hydraulic valve. The reliable operation of solenoid actuator effects on the overall hydraulic system. The performance of solenoid actuator relies on frequency response and step response according to arbitrary input signal. In this paper, we performed the analysis for the components of solenoid actuator to satisfy the reliable operation and response characteristics through the reliability analysis, and also deducted the design equations to realize the reliable operation and fast response characteristics of solenoid actuator for hydraulic valve operation through the empirical knowledge of experts and electromagnetic theories. We suggested the design equations to determine the values of design parameters of solenoid actuator like bobbin size, length of yoke and plunger and turn number of coil, and calculated the life test time of solenoid actuator for verification of reliability of the prototype. In addition, for reducing the life...

Summary
The solenoid actuator is a very economical motion converter due to its simple structure as electromagnetic energy converting to kinetic energy. One is the optimal design method for solenoid actuator. For the optimal design of the solenoid actuator, theoretical and empirical knowledge are simultaneously needed. Theoretical knowledge governs the operational characteristics of the solenoid actuator, and empirical knowledge compensates for the theoretical limitation obtained from the designer’s design and manufacturing experiences for various kinds of solenoid actuator.[1] They cannot be determined solely by calculation or simulation because the empirical knowledge is more essential than theoretical knowledge for determination of the plunger shape and value of the space factor. To establish the reliability assessment technology of solenoid actuator, we performed the failure analysis considering the literature, failure data of manufacturing companies and the opinion of experts, and produced the reliability parameters for design and test. The no-failure test time of solenoid actuator is calculated. For reducing the no-failure test time, the acceleration model of solenoid actuator is proposed, and the acceleration factor is calculated with the reality.
