Dynamic load simulation testing instrument and simulation testing method

Abstract

The invention relates to a dynamic load simulation testing instrument and a simulation testing method. The dynamic simulation testing instrument comprises a servo motor, a servo driver with a moment driving mode and load setting and loading and parameter display software, wherein the load setting and loading and parameter display software can send a control command which simulates the position-moment relation of an actual mechanical structure to the servo driver through a bus for controlling the motion of the servo motor, and the servo motor is in reverse connection with a tested motor through a coupler. The simulation testing method comprises the following steps: controlling the operation of the simulation testing motor and the tested motor through the load setting and loading and parameter display software, using a PC (personal computer) to control the simulation testing motor driver to apply a moment which is reverse to that of the tested motor on the simulation testing motor by adopting the moment control mode through the load setting and loading and parameter display software, and further performing simulation testing on the tested motor. The simulation testing instrument and the simulation testing method have the advantages that the instrument has simple structure, and is convenient to operate and maintain; and the dynamic loads of various different mechanical structures, such as a cam and the like, can be simulated.

Description

technical field [0001] The invention relates to a dynamic load simulation tester and a simulation test method, which are mainly used in occasions requiring simulation and testing of parameters such as drivers and motors in the field of industrial automation, especially suitable for occasions requiring simulation and testing of dynamic loads. Background technique [0002] Motors and drives widely used in industrial production, automation and other fields usually require performance testing before leaving the factory, and parameter adjustment is required in field applications. [0003] The commonly used test method today is: the driver controls the motor movement, and at the same time, the dynamometer is connected to the motor through a coupling, a reverse torque is added to the motor, and the parameters of the motor and the driver are tested by observing the data displayed on the dynamometer system. [0004] It is also possible to simulate the on-site application of the motor...

AI Technical Summary

Problems solved by technology

[0004] This method can also be used to simulate the field application of the motor and the driver, but the dynamometer can only output a constant torque, which is almost impossible in the application, and it cannot achieve a good simulation debugging effect

On-site debugging after installation, the debugging effect is not guaranteed due to the harsh environment, wasting a lot of time

For example, a mechanical structure often used on CNC machine tools—the cam mechanism, due to the irregular nature of the cam mechanism along the circumferential direction, the force on the motor shaft at each angular position is different when the motor moves for a circle, which is not easy to simulate and debug
