Microcomputer control spring testing machine, used in the comprehensive compressive performance test of various locomotive springs, it adopts precision ball screw structure and is equipped with a transverse measurement system on the first pressure plate. It can measure the lateral force generated by various springs under pressure at 360°, and can test the axial load, lateral displacement, lateral force and lateral stiffness of the first and second series circular springs of the harmonious high-speed electric locomotive, and can automatically analyze the bending direction, stiffness value and other data; And draw the printing axial load-deformation or deflection, lateral force-lateral displacement curve. The whole test process is controlled and completed by computer.
