This work presents a new type of vehicle maintenance lifter for position tuning 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. This parameter study is performed by magnetic field analysis using ANSYS. After determining the optimized design values, the field-dependent pressure drops of the optimized MR valve system are experimentally evaluated and compared to those obtained from the initial design. Subsequently, the position of the vehicle maintenance lifter is controlled by change of pressure drop using PID controller. It is demonstrated that the proposed vehicle maintenance lifter can be effectively applied to the vehicle maintenance service center for more accurate tasks.
