Description
technical field [0001] The invention relates to a reliability experiment device for a servo electric cylinder, more precisely, the invention relates to a reliability experiment device and a testing method for a servo electric cylinder based on a load spectrum. Background technique [0002] Due to the advantages of energy saving and cleanness, long service life, and simple operation and maintenance, servo electric cylinders are widely used in many industrial equipment. Similarly, compared with hydraulic cylinders, servo electric cylinders have a simpler structure and higher reliability. The servo electric cylinder is a modular product obtained by integrating the design of the servo motor and the lead screw. Torque control, precise speed control, precise position control, precise thrust control are retained, so as to realize a series of high-precision linear motion products. Servo electric cylinders can be widely used in experimental equipment such as high-frequency vibration...
