Simulation Calculation Study on Solenoid Valves in ABS System

Based on the structure of a typical ABS solenoid valve, the calculation models of the electromagnetic characteristic and mechanical characteristic are created, and the simulation calculation software is developed. The current characteristic of the solenoid valve is in real time detected on the computer hardware closed-loop system, and the coilenergized time and the valve action time are obtained. The correctness of created model and developed simulation software on calculating the response time of the solenoid valve is partially verified by the experiment result. The factors influencing the characteristic of the solenoid valves are discussed, and the relationship between the solenoid valve action time and struclure factors such as the lengths of main work air gap, section area of magnetic path coil and absorption resistance, coil turn and return spring stiffness is established.
