Design of Electric Linear Simulation Loading System for Gas Force Simulation

The electric linear simulation loading system can simulate the gas loading force of gas regulating valve under the laboratory conditions. The electric linear load actuator as the output mechanism of electromagnetic force needs to have certain reliability and precision guarantee. According to the design goal, this paper designs a moving coil type the electric linear load actuator. It has the advantages of high precision, fast response and good controllability. It can be applied to low and medium loading occasions. Simulation and experiment results show that the steady-state error of the electric linear load actuator under static loading is less than 2%. The electromagnetic force of the prototype is stable and smooth, and can reach more than 400N. The electric linear simulation loading system is a semi-physical simulation system, which reduces the research cost and cycle of the load-bearing object. Therefore, the research of the electric linear load actuator has great practical significance.
