Abstract

The invention discloses a load simulation testing device for a rudder system. The load simulation testing device comprises a torque sensor, a torque device and a first torsion rod spring, wherein thetorque sensor is used for measuring the torque of a rudder actuator; the torque device is used for providing load for the rudder actuator in a non-linear load mode and an inertia load mode; the firsttorsion rod spring is used for providing load for the rudder actuator in an elastic load mode, and in the elastic load mode, one end of the first torsion rod spring is connected to the rudder actuator, and the other end of the first torsion rod spring is arranged fixedly. In the testing device, through the arrangement of the torque sensor, the torque device and the first torsion rod spring, the stimulation testing for the rudder system in different load modes can be realized, and the device is simple in structure and convenient to operate.

Description

technical field [0001] The invention relates to the technical field of rudder system load testing, in particular to a rudder system load simulation testing device. Background technique [0002] The steering gear is the executive mechanism to ensure the stable and controlled flight of the aircraft, and its performance directly affects the control accuracy and hit rate of missiles and other aircraft. In order to verify whether it can maintain a good working condition in the high-altitude complex environment, the performance index of the rudder system under the load test is the main aspect reflecting the comprehensive performance of the rudder system. The load condition loads the torque on the steering gear to test its dynamic performance and control accuracy under the loaded state, so as to realize the dynamic performance of the steering gear under the approximate actual load in the laboratory environment. However, the existing load simulators are complex in structure and inc...
