Optimal design and analysis system of AC solenoid valve

Solenoid Valve is a kind of typical low voltage electrical appliance with special working characteristic. Take FDF (FDF is a series of model of solenoid valve Sanhua company produces) series solenoid valve for example which applied widely in refrigerating system. Its temperature rise, vibration noise and so on are key points affecting the product quality. At present, the research on solenoid valve mostly specific to the field in system response time and structure design and it lacks the analysis on the overall performance indexes and optimal design. Therefore, the development of miniaturization, less consumption of the energy and the artificial intelligence of solenoid valve will be restrained. The simulation analyzing system for dynamic characteristic and temperature calculation in working state, dynamic characteristic analysis and integrated optimized design is built and it forms unique database of electrical appliance characteristic analysis and simulation design. It focuses on optimization design module in this paper. The changing regularity of the temperature rise of the electromagnetic mechanism is researched and concluded based on the 3D simulation in electromagnetic and temperature field. And the regular is brought into the optimization design of electromagnetic mechanism. Ant colony optimization is used in the optimal design for the overall performance index, and the dynamic process of the closing state and closed in long term working state are also considered at the same time. The design result is quite satisfied.
