Abstract


Flying car is a new concept of craft combined with auto transportation, it givesconsideration to long distance driving and short distance navigating.Under such a request, thestructure strength and lightweight of body of frame become a prominent contradiction.Inorder to solve above questions,in the former stage based on the research of the project group,the paper designs the comprehensive type frame and analyses the strength and stiffness offrame and the dynamic performance.According to the flying car’s overall design and the study of body frame shapeconstraints,it determines the comprehensive frame as a flying car body frame form.Thecomprehensive frame could be divided into former vice frame,central backbone, rotorpillar,after vice frame.By comparing analysis aluminum and steel metal’s properties,processing technology and price factors,the paper selects7050-T7451as vice frame material,Q420steel alloy as the central backbone and rotor pillar material.It builds3D model of frameby using CATIA software;selects the bending working condition and jump takeoff conditionand exactly the same external load and analyze the stress,strain,dynamic modality ofcomprehensive frame and space tube body frame,get the corresponding data and dynamicgraphical display by using ANSYS software.The research mainly focuses on the road and theengine incentives influence on comprehensive frame and space tube body frame vibrationseparately.By contrasting analysis the statics performance and dynamic performance of twokinds of frame, get the advantages and disadvantages of two kinds of frames.,So it makes theconclusion,draw for flying cars,comprehensive frame is better than space tube bodyframe.The advantages reflect some aspects:strength and stiffness of frame,dynamicperformance of frame, the external incentives influence on frame vibration respectively.Themost important thing is that on the premise of having lightweight space,comprehensive frameis21.62kg lighter than space tube body frame,which accounts for about18.8%by weight of the frame.
