The Opening And Closing Performance Simulation And Control Research Of Bus Outside Sliding Door

With the development of automobile industry and the increase in traffic, people are also rising the requirements on the bus shape, quality and comfort. The research of the outside sliding door open and close not only has good performance, and the bus with good air power, fuel economy and travel convenience. This paper focuses on the performance of the outside sliding doors open and close and the start of motor control, specifically to do the following tasks:1,Aaccording to literature data, analysis the rotation sliding doors and electric door system works and carried out detailed to simplify the complex in the settlement put the organization, increase the motor output power, and change sliding friction to rolling friction ,using a floating motor bearing for the outside sliding door crank institutions. And use closed vector method to analysis the crank theory.2,Create three-dimensional model of the outside sliding doors in the UG software, and the model is imported into ADAMS / View, the solution achieved by using the cam roller and slide Vice bound, achieved by three Vice-slip trails constraints and several other difficult issues, establish of a virtual prototype of the outside sliding door.3,The motor speed can be achieved for the purpose of the outside sliding door open and close by the ADAMS software.Using IF function, combined with the STEP function, which can meet the design requirements, but also solved a single function in the numerical simulation is easy to produce mutants problems. After several simulations to determine the optimal time and speed parameters, the preparation of the motor function of variable speed drives, variable speed to achieve the door open and close.4,The outside sliding door opening from the research point of view the best performance. In two conditions of the uniform opening and closing and opening and closing speed, the main sliding door opening in external friction,the outer sliding door opened acceleration and closed on the hoist motor output torque performance. And on this basis, using MATLAB software to draw electrical power output curve of the two conditions. Simulation analysis showed that motor function driven by variable speed drives, the outside sliding door in variable speed open and close able to achieve a smooth, soft and open and close, suffered little impact.5,The choices of the sliding door open and close speed conditions, the use of PLC controls the motor speed, motor acceleration - constant speed - the case of slow rotation, sliding doors can be achieved outside the doors open, the door keeping and the doors closed three steps. And through programming to the outside sliding doors with obstacle detection, anti-trap function of the hand.
