Problems solved by technology
[0003] The existing testing machine has a relatively low kinetic energy adjustment efficiency in the process of performing durability and performance tests on the ball screw, and only directly adjusts the rotation speed of the servo motor. For the complex actual working process of the ball screw, It is impossible to simulate the actual working environment during high-speed and low-speed rapid switching, which reduces the durability and performance accuracy. Secondly, the heat dissipation effect of the testing machine is relatively poor during high-speed rotation, which further affects the parts of the testing machine itself. The problem of causing damage and reducing the service life of the testing machine
