The Study of Wheeled Semi-trailer Design and Development Based on Scale Model

Abstract

The wheeled semi-trailer is usually used to transport heavy-duty equipment, engineering machinery and other heavy-load cargo. With the wheel semi-trailer, it is convenient to transport the heavy-duty equipment to the destination area and will play a great role in heavy-duty transportation for long distance. Nowadays, the relative enterprises all over the world focus on the modern design methods which could enhance the manoeuvrability, the ride and flexibility of the semi-trailer. The scale model we used in the research is a 50:1 semi-trailer simulation model. The reverse engineering technology is adapted to primarily design the relative parts and components of the wheeled semi-trailer. Then, the digital mock-up technology is used to design the details of the whole vehicle model. Finally, the optimization is completed for solving the relative problems in the multi-axis turning. For the limitation, the testing data for manoeuvrability could not be gotten, so the simulation precise can not be checked for further improving design. The semi-trailer simulation model is firstly used rather than the actual vehicle for the development of vehicle designing. Diversified methods and technologies is adapted successively and the optimization 3-D model is achieved. The simulation results show fine multi-axis turning condition. The development cost is cut and the development cycle is shortened. All above will provide the valuable references for the research of the wheeled semi-trailer.
