Study Of Erected Circular Mechanical Garage Structure Design Base On CAE

This articles analyses the reason and effect of parking crisis. The characteristic of erected circular mechanical garage and the study of structure design base on CAE is described in it.Firstly,It is analyzed that the external form dimension of 93 kinds pop car, and the confine dimension of vehicle decided. The structure design content and flow is set down. The technologies of CAE is applied in the study, such as finite element method, optimum design and motion simulation. The research scheme is worked out, Three kinds models are set up to comparative analysis in finite element analyse with three kinds instance. It explains the function and characteristic of multi-ribbed plate. The thought of optimum designs is ascertained, the influencing factor of the optimum designs and the method of motion simulation are analysed.Secondly, in the hanging basket design, the multi-ribbed plate is design and three kinds models finite element method comparative analysis is carried out by COSMOS-Works. The result of study is indicated that the wheelbase is more shorter, the deformation of floor carring vehicle is more higher with the same vehicle weight in analyse range, that the deformation of multi-ribbed plate is the shortest in three kinds models, the maximal deformation displacement is 0.72mm, and that the multi-ribbed plate is the strongest because of its assurance coefficient is more than 3, however, the thickness of steel floor in multi-ribbed plate is minimal, the thickness of steel floor is 3mm in the area that vehicle wheel rolled, the rest is only 1mm. So it has lighter weight. Thus it can be seen that there is obvious effect of reducing weight and increasing rigidity and intensity when the multi-ribbed plate is used in engineering.Thirdly,in the transport chain design, the hanging basket model is simplified.basing on the theory of optimum design, design variable is choiced, the constraint is confirmed with some condition,such as instensity of chain plank, equipment setting dimension, the relation of pitch circle diameter and sprocket tooth number and so on. The optimum design function base on the nonintervention condition of hanging basket movement is set up. It is solved by MATLAB. The sprocket tooth number is rounded and the chain parameter is finally obtained, pitch P=630mm, sprocket tooth number z=11, pitch circle radius R=1118.1mm, outside stretches amounts of chain T-plank C=400mm, gyration radius of hanging basket L=1518. 1mm.Finally, the movement medo of hanging basket movement is designed by COSMOS-Motion. After constraint and collision is set up, motion simulation is carried through to validate the nonintervention of hanging basket movement. It prove the success of optimum design base on the nonintervention condition of hanging basket movement.The article concludes that the erected circular mechanical garage with reasonablely structure can be schemed out availably with high strength and high rigidity .It is important to popularize mechanical tridimensional garage.
