The movement analysis of centripetal suspension on double axle semi trailer is carried out.

Structure design and strength and stiffness analysis of an SGA92150 semi-trailer frame;

Structural design and finite element analysis of SGA92150 semi-trailer s frame;

Structural design and FEA of gooseneck of the 120t concave semi-trailer;

In this paper, Parameter Variable technique is used to establish finite element model for trailer frame of 60 ton heavy transport truck , and 10-Node Tetrahedral Structural Solid elements are used for FEM mesh, which greatly improves building efficiency , revisability and of model than tradition methods.

In the side wind the truck with a trailer is liable to deviate from the right direction,and also the tractor and the trailer are not able to keep in line,so that handling performance is affected.

The author of this paper presents a group of formulas for designing optimally the wheel base of a hauling automobile and the span length of a trailer, on basis of analyzing and studying systematically wheel bases of hauling automobiles at home and abroad and span lengths of trailers at home and abroad by means of Structural Mechanics, Automobile Structur Caurse and Automobile Theory Course.

By means of the vibration testing of the CNG traffic semi trailer,makes a comparison between the use of the imported and the national vehicle on the Chinese way,then puts forward the improvement who can make the national vehicle better.

In this paper,according to the demand of market and structure characteristics of products, some specific measures and methods are presented in detail when modularity design is used for a series of semi trailers in our factory.

Aiming at solving the problem of bending deformation of longitudinals of semi trailers due to unregular load distribution,the authors introduce a structural manufacturing pross of longitudinals with deflection.
