Problems solved by technology

The traditional air rudder performance evaluation method is relatively simple, and the assumptions used in theoretical analysis are idealized, which makes it difficult to truly reflect various performance indicators; the method and results of simulation analysis need to be verified by experiments; the performance evaluation of air rudders under various operating conditions The test plan and the design of the test device cannot be closely combined, resulting in a single function of the test device and the inability to conduct a comprehensive assessment test

Abstract

The invention relates to an aircraft air rudder performance assessment method. The method includes the steps that an air rudder system static stiffness and dynamic stiffness (torsion frequency) analytical expression is established, an air rudder system finite element model is established, air rudder system basic rigidity, part stress strain, deformation and other properties are analyzed, an air rudder performance test method is made, and an air rudder test device is designed. The air rudder bearing performance, static stiffness, dynamic stiffness, transfer function and friction property of an aircraft are obtained by combining air rudder performance theoretical analysis, simulation analysis and experimental testing, and comprehensive assessment parameters and the reliable and the convenient assessment method are provided for optimization design of aircraft air rudders and air rudder performance comprehensive assessment.

Description

technical field [0001] The invention relates to an aircraft air rudder performance evaluation method, which belongs to the field of mechanism system performance analysis and testing. Background technique [0002] The air rudder of the aircraft is connected with the fuselage structure through the transmission mechanism, and the air rudder achieves the purpose of adjusting the attitude of the aircraft by deflecting within a certain angle range. The performance of the air rudder system is the result of the combined effects of various factors, such as the configuration of key components of the transmission mechanism, the modal and stiffness characteristics of the rudder surface body, the cooperation between components, load conditions and environmental conditions, etc. All affect the stability of air rudder performance, yaw accuracy, transfer function characteristics, etc. Stiffness is the first element in the design of the aircraft air rudder system, and the design efficiency ...
