Optimization Analysis Of Wingcraft Aircraft Mechanism Based On MATLAB

From ancient times to the present,flying in the sky is the dream of people.After thousands of years of research,the most widely used aircraft currently are fixed wing aircraft,rotorcraft and flapping wing aircraft.However,the use of natural biological research aircraft flight characteristics imitation,it has good emotional flexibility,high lift drag ratio and relatively small size,less energy consumption,so the comparison of fixed and rotary wing aircraft is used more and more widely,at present in the civil and national defense and military field have a very good application.This thesis firstly introduces the analysis of the flapper-wing aircraft transmission mechanism,selects one of the fixed crankshaft and rocker linkages as a research model,establishes a mathematical model,and finally obtains the optimal calculation formula for each parameter of the target model.It lays the theoretical foundation for the following researches;through the classification of the currently researched flapping wing mechanisms,the scale laws of the various types of flapping-wing aircraft are analyzed,and through comparative studies on the scale ratios between the same class,three are obtained.The fitting formulas between the parameters of the flapping-wing aircraft of similar flying organisms are based on this;based on this,the dynamic problems of the drive system of the flapping-wing aircraft are analyzed by using ADAMS software,and the traditional mechanism of flapping-wing aircraft is mathematically adopted.The establishment of the model,the solution of the model and the derivation of the model yielded the best model,and studied the dynamics of the aircraft from the three aspects of constant force,inertial force and damping force,including adding spring devices and not adding The spring device performs a comparative analysis to investigate the input power of the transmission and from the perspective of energy transfer Analysis of the springmechanism of the peak input power reducing means;installed on the modified asymmetric spring mechanism,this mechanism has been well verified.Finally,considering the shortness of life of the Winged Aircraft aircraft,and based on previous research,the company proposed to use solar panels to make wing flaps of the Winged Aircraft aircraft.The wing wings made by the solar panels are in the process of flapping.Solar energy was collected to provide auxiliary energy for the flapper aircraft.The theoretical calculations verified the feasibility.
