Abstract
An accurate position control is demanded in the current hydraulic lifter used for vehicle maintenance. This work presents a new type of vehicle lifter for precision position control using a magnetorheological valve system. In the first step, the principal design parameters such as gap size of oil passage, length and depth of coil part, and distance coil part from the end of valve are considered to achieve the objective function for getting the highest position accuracy under current input constraint. After determining the optimized design values, the field-dependent pressure drops of the optimized valve system are experimentally evaluated and compared to those obtained from the initial design. Subsequently, the position of the vehicle lifter is controlled by change of pressure drop using a simple PID controller. It is demonstrated that the proposed vehicle lifter can be effectively applied to vehicle service center for more accurate tasks under proper height.
