Abstract

The invention provides a hollow spindle type electro-hydraulic load simulator. The hollow spindle type electro-hydraulic load simulator comprises a motor shaft used for generating a loading torque, wherein the motor shaft is in the form of a hollow structure; a loading shaft, wherein at least a part of the loading shaft is located in the hollow structure of the motor shaft; and a torque sensor which is integrated on the loading shaft. The loading shaft is connected with the motor shaft through a first connection so as to receive the loading torque generated by the motor shaft and transmit theloading torque to a loading object through a second connection.

Description

technical field [0001] The present disclosure relates to a hollow-spindle electro-hydraulic load simulator. Background technique [0002] As aerospace equipment, the steering gear of rockets, missiles or aircraft is often subject to huge air loads, large values, high frequencies, and severe vibrations during operation. In order to ensure the safety of the aircraft, when the steering gear is manufactured, it must It undergoes strict examination. During the assessment test, it is often necessary to simulate the actual working environment and apply an accurate load to assess whether the performance indicators of the product meet the design requirements, and the equipment needed for the assessment of the steering gear is the load simulator. [0003] The electro-hydraulic load simulator has the characteristics of high operating frequency band and strong output capability. In recent years, the cruising speed and dynamic characteristics of aircraft have been increasing, and there...
