Research and design for test bench of electromagnetic regenerative suspension was worked out. The test bench has the integral frame structure, includes mechanical vibration, 1/4 vehicle electromagnetic energy regenerative suspension and test data acquisition system. Based on multi-lever principle, mechanical vibration stimulator was manufactured. Electromagnetic feedback suspension has the structure including the spiral spring, a ball screw rod and a motor, and also retains the wheels and tires. The test data acquisition system was build using Labview. The entity model, mechanical model and mathematical expression of the test bench were established. MATLAB simulation model for the test bench was established. Parameters of the test bench and the simulation model are determined by the comparative analysis of simulation and test data, analysis result shows the test bench of electromagnetic regenerative suspension was practical and reliable, and can meet the requirements of the test research on the theory of suspension.
