A high-torque high-performance electric variable loading device

Abstract

The present invention discloses a high-torque and high-performance electric load-variable device. The device comprises a torque sensor, a controller, a loading motor driver, a loading motor and a mechanical transmission shaft. The torque sensor is connected with a steering engine system and a controller to collect current moment information on the rudder shaft of the steering engine system and send the current moment information to the controller; the controller is connected with a simulation system and the loading motor driver to determine the controlled quantity of the next moment according to the torque instruction and the current moment information of the simulation system and send the controlled quantity to the loading motor driver; the loading motor driver is connected with the loading motor to drive the motion of the loading motor to generate the corresponding moment under the action of the controlled quantity; and the loading motor is connected with the mechanical transmission shaft and the steering engine system in order to apply the moment to the rubber shaft of the steering engine system through the mechanical transmission shaft so as to realize the accurate control of moment loading on the steering engine system.

Problems solved by technology

However, the electro-hydraulic load simulator has a large pollution and is difficult to maintain, so it has been gradually eliminated.

[0004] In addition, the current electric load simulation equipment on the market has a maximum loading torque of 500Nm and a loading frequency of 20Hz. Due to limitations in loading torque and frequency, the response speed is slow and it is impossible to accurately control the loading torque.
