Abstract

The invention discloses a rocker type linear electromechanical actuator performance test stand, which can meet the performance test of different types of linear electromechanical actuators in rocker arm installation and horizontal installation states. The test stand can adjust the height of a dovetail slide assembly 3 to change the included angle between the linear actuator to be tested and a drive rocker arm. By adjusting the position of a dovetail mounting bracket 2, the test stand can be adapted to installation of different neutral-length actuators. The entire test stand is modularly designed to accommodate the various performance tests of linear electromechanical actuators under different operating conditions. A linear actuator assembly to be tested 5 and a loading assembly 10 of the test stand can be installed by a swing arm or horizontally installed, and the actual working state of the linear actuator to be tested can be simulated by replacing different rocker arm assemblies. Thetest stand can install a stiffness simulator assembly 4 and an inertia simulator assembly 6 to complete real-time monitoring of test data.

Description

technical field [0001] The invention relates to a mechanical device of a rocker arm type linear electromechanical actuator performance test bench. Background technique [0002] Linear electromechanical actuators are small in size, high in efficiency, light in weight, strong in survivability and easy in maintenance, so they are widely used in flight control systems, precision machine tools, robots and industrial process control, especially in modern all-electric aircraft and weapons. and other fields, linear electromechanical actuators have been widely used in aircraft rudder systems. The linear electromechanical actuator acts as a flight control steering gear, and its actuation performance will directly affect the performance of the aircraft. The spatial installation of the linear electromechanical actuator also affects its output characteristics. Therefore, it is necessary to establish a test bench that can simulate the actual working and installation environment of the l...
