| With the development of our cities and the steady increase of the quantities of cars, high-tech stereo-garage has become the developing trend of the parking location. As a part of stereo-garage, the elevator for car is playing an important role in parking industry. But due to the traditional designing methods which are generally adopted nowadays, the quality of the parking equipments can not be ensured, therefore stereo-garage has not been widely used in our country. Herein this situation, it needs new design methods to create the products faster. This paper establishes the model of the transmission system of the PQS-3-D Elevator for Car with the traditional approach of modeling and analyzes the model in vertical direction to meet the needs of market and design.In this paper, firstly, the deformation of flexible components is considered, and then the vertical model is set up with the traditional approach of modeling. The parameters of components, such as mass and the moment of inertia, are deprived according to their solid modeling in Solid Edge. Secondly, by analyzing kinematics of members when the system operates stably in the conditions of rigid, acquired velocity rating and rated angular velocity etc. And then, according to the requests of management, speed of car runs along S curve, inversely solute the stimulate matrix and establish Lagrange dynamical equation ofthe system. Then use the analysis software--MATLAB to make out the model accurately,and gained the instantaneous displacement, the instantaneous velocity and the instantaneous acceleration of the car as well as the relative driving component, besides analyze the deferent curves and discover that the curves accord with the practical instance basically. Also compare the instantaneous displacement with the one when without regard to the elasticity, and gained the difference value of the displacement in the two conditions. According the above work, utilize the rigidity coefficient which changes along with the... |
