Automatic suspension spring stiffness performance testing

　　Automatic suspension spring stiffness performance testing equipment and equipment features

　　1. Suspension spring stiffness performance testing equipment using highly integrated, powerful control, data processing capabilities, high-reliability high-speed DSP platform;

　　2. The testing equipment adopts three closed-loop (force, deformation and displacement) digital control system based on neuron adaptive PID algorithm, the control loops can be switched automatically and the impactless smooth transition can be realized when switching between modes;

　　3. A testing machine integrated tensile, stripping, tearing and other seven separate test program, to provide users with a variety of test options;

　　4. Closed-loop control parameters online identification; can test force, deformation, displacement and other rate control and maintenance;

　　5. The entire control system has a high cost, high reliability.
