| The construction of mechanical stereo garage can effectively solve the problem of parking in the city.Among them,the structure and performance of the non-avoidance stereo garage which has a distinctive structure of a single-column and cantilever beam need to be optimized and verified on the basis of kinematics and dynamics analysis as well as experimental study.Based on the theory of rigid-flexible coupling modeling,the rigid-flexible coupling model of the stereo garage is established by means of multi-software co-simulation.The kinematics and interference of the stereo garage are studied by kinematics and dynamics analysis.At the same time,the dynamic performance of the key bearing parts and components is verified by the dynamic analysis.The results show that the dynamic mechanical properties of the relevant parts are basically in accordance with the design requirements.By the way,the rationality of modeling and simulation with ADAMS is verified through the contrast between simulation analysis and theoretical calculation as well as experimental analysis.There comes a contradiction through the experimental study of the non-avoidable stereo garage and the above-mentioned dynamic simulation analysis.It leads to lack of constraints when the gap between main body of the stereo garage and the tracks which caused by processing and assembly errors is too big.On the contrary it leads to assembly difficulties and stuck.Based on this,the contradiction has been solved through the optimization of the distance of the walking axles and the design of gap adjustable devices,and the static performance of the new structure is verified.The simulation data shows that the optimized structure has better motion and dynamic performance. |
