Research Of Lateral Slide Of Cars In Mechanical Roller-Path Parking System

Mechanical roller-path parking system is a new kind of parking system. In the roller-path parking system, there are continuous and longitudinal arranged free rollers on the hoisting carrier and parking area, the cars are supported by the rollers. The cars are pushed in or pulled out by the position mechanism which can be folded and is located between the front and rear wheel supporting roller-path. Based on the structure design of roller-path parking system, the potential lateral slide in the condition of cars access or leave the parking system is a very important challenge and should be verified.Cars with different driven means may response differently to the lateral slide when the cars access or leave the parking system for the reason that the driving wheels and free rolling wheels effect different to the free roller. Also cars in different class or with different initial deviating angle perform different when access or leave the parking system, bigger initial deviating angle effect much more to the lateral slide.For cars with different driven means, the force model and kinemics model are built both in the condition of cars accessing or leaving the parking system. The parameters deviating angle and lateral velocity which represent the gesture change of cars are calculated, and according to the response of deviating angle and lateral velocity of cars in different conditions, with different driven means, in different class and with different initial deviating angle, it is found that the cars will swing periodically, adjusted to lateral direction automatically or further deviate. But, take the real condition into consideration, the lateral slide will happen in a very short time, it will not influence the vehicle accessing or leaving process very much.
