Multi-Objective Optimization and Analysis of Tri-Stable Permanent Magnet Actuators for Valve Application

Blog Article

Tri-stable permanent magnet actuator (TPMA) has been widely used in industry.In this study, a new TPMA integrating a permanent magnet actuator and two centralizing disc springs is proposed for valve application.By taking the linear coefficient of force/stroke characteristic, startup force, holding force and response le boudoir de luna cognac time as the optimization objective, the TPMA was optimized based on an improved hierarchical genetic-particle swarm algorithm (HGP) and 3D Finite element analysis (FEA) under volume constrain.The optimization process was analyzed in detail to prove the effectiveness of multi-objective design.

The performance of the prototype was verified experimentally.The results showed that a good linear force/stroke characteristic of prototype was obtained, and the linear coefficient of force/stroke characteristic was 0.97.The startup force was 409 N and holding force was ted lasso energy drink 332 N, which increased by 32% and 54% after optimization, respectively.

The dynamic response time of prototype from center stability to extreme stability was 5.8 ms.The TPMA can be applied extensively in the valve control.
