Research On Dynamic Performance Of Road Single Guide Rail Rubber Tire Vehicle

With the development of social economic, acceleration of urbanization, urban population has became more and more concentrated, the number of vehicle has increased sharply, due to the increasingly urban traffic congestion,the city have to face the higher and higher requirements. Thougth its speed,green energy,safe punctuality, low investment cost,volume and other characteristics, Urban rail transit development are widely recognized and applied around the world,in addition it derived varytraffic types.Road single guide rail rubber tire vehicle unique oriented approach, the wheel-rail contact relationship became different than ever. Traveling with its orbital road surface, based on the road surface in a metal guide rails laid to guide the vehicle Rubber tires used to carry and drive, so that the vehicle climbing ability, through the curve radius, running noise, ride comfort. And its small footprint, short construction period, low-cost single-oriented features make the road single guide rail rubber tire vehicle can be used as a large, one medium-sized cities optional standard mid-size mass transit lines. Road single guide rail rubber tire vehicle own more and more attention and has been applied in Tianjin and Shanghai,.In my issue there are lots of performance research about this guide rails on the road single tire vehicle, it has a certain significance application in China.This article describes the structure type of the road single guide rail rubber tire vehicle and its advantages and disadvantages,it also reveals its international history and the development of application Highlights.The issue importantly introduce the working principle and characteristics of Translohr road single guide rail rubber tire vehicle bogies and rubber tire vehicle. The structure and mechanical properties of rubber tires, and the corresponding mathematical expressions. To establish a tire mechanical model using "MF" model in Simulink circumstance,and simulation analysis carried out in two working conditions of swerving and braking.According to the vehicle system dynamics modeling simulation theory, a road single guide rail rubber tire vehicle dynamics equations. The establishment of Translohr road single guide rail rubber tire vehicle dynamics simulation model in multi-body system dynamics software SIMPACK, the analysis of the guide bar length of the vehicle by the properties of the curve. Because a road single guide rail rubber tire vehicle running road surface and its unique guide the vehicle derailment phenomenon does not exist in the traditional sense, the main indicators of the vehicle to ride on the road single guide rail rubber tire vehicle suspension parameters were optimized to obtain a more reasonable configuration parameters. Finally analysis the dynamic performance of the road single guide rail rubber tire vehicle.The results show the perfonnance of curves Translohr road single guide rail rubber tire vehicle’s length guide rod and guide mechanism for guiding the ability to influence and vehicle passes. Pavement parameters optimized single guide rail vehicle tire with good ride and meet GB/T4976-1996 standard, most comfortable feeling to passenger. Road single guide rail rubber tire vehicle empty weight of car tire in no wind and crosswind action under each curve through the working conditions, with good performance of curve.Research papers provides a theoretical reference for guiding development of China’s road single track rubber tire vehicle.
