The purpose of this paper is to study the stabilization of the force generated by the suspension (Hereinafter, referred to as damping force) which is applied with hydraulic control valve by electronic control by controlling the pressure with a variable magnetic force through a solenoid of a suspension. (Hereinafter, referred to as an Electric Control Damper) To this, hydraulic control valve was analyzed in terms of the structure and fluid flow, and results were derived through an experiment.
The electronic control damper has a key mechanism for recognizing a condition of road surface to change the magnetic force of the solenoid through the current control and control the pressure by using the damping force required for controlling the behavior of the vehicle body according to the situation. Accordingly, the purpose of this study is to analyze and consider the effects of a magnetic force rapidly changing according to a situation on a pressure system.
For stable pressure part control, the spring was set as a control factor through governing equation of pressure control mechanism, and the design and applicable coil spring stiffness values were verified through analysis and experiment.
In this study, in addition to examining the operation of the suspension, it was applied to mass-produced vehicles, and a comparative test was conducted on the effect of stable damping force control on the actual vehicle to evaluate and confirm the effect of operating vibration.
