The system comprises a main control computer, a server, a structural static property testing system, a structural dynamic property testing system, a pneumatic response analysis system, a structural response analysis system and a coupling response analysis system, all of which are connected to form a uniform integrated body through an optical fiber system. The main control computer is connected with the structural static and dynamic property testing systems and the server; the server is connected with the structural, pneumatic and coupling response analysis systems to control the three systems; professional analysis tools of the three response systems operate respectively, and finally, the analysis results are returned to the server while feedbacks are output. According to the invention, the difficulty of data exchange of the micro flapping-wing design and the comprehensive analysis of the pneumatic and structural coupling properties with two subjects is effectively overcome; the comprehensive analysis of complex problems involved with the pneumatic and structural subjects and automatic coordinated operation are realized; the design cycle of the micro flapping-wing is shortened; the design efficiency is improved.

Description

technical field [0001] The invention relates to the overall design technology of aircraft, in particular to a micro-flapping wing analysis system and method taking into account aerodynamic and structural coupling characteristics. Background technique [0002] The flapping wing aircraft is a bionic aircraft that imitates the flapping wings of birds and insects. Unlike traditional aircraft, the lift and thrust required for the flight of the flapping wing aircraft are completely generated by the periodic motion of the flapping wing. The aerodynamic performance of the flapping wing becomes The key factors that affect the performance of the aircraft. The research shows that the aerodynamic performance of the flexible flapping wing with reasonable stiffness distribution and flexible deformation ability is significantly better than that of the rigid flapping wing, which is the main direction of the current development of flapping wing aircraft. During the reciprocating motion of t...
