Study on Multi-Objective Simulation Optimization of Flow Characteristics of Solenoid Valve Injector

A one-dimensional simulation model of AMESim solenoid valve injector was established. The key structural parameters of the injector were simulated and analyzed. The influence of structural parameters on the flow characteristics of the injector was analyzed. Based on the response surface test design method, Design-Expert software was used. The regression equations of static flow and dynamic flow range and key structural parameters are sought. The multi-objective simulation optimization design of key structural parameters of electronically controlled injectors is based on static flow and dynamic flow range. The multi-objective simulated annealing MOSA optimization algorithm was used as the optimization strategy. The optimized injector static flow increased by 2.3% to 0.135L/min; the dynamic flow range increased by 6.1% to 5.2.
