Abstract: In order to create three dimensional solid models and verify designing parameters for trailer, a typical trailer structure was presented. The basic components of the trailer system were introduced. And the operating parameters were designed on the basis of analysis of the main work flow. Using the 3D design software CREO2.0, the model of the trailer was built based on the parameter design. Based on the solid model, the finite element analysis software Abaqus was used to simulate the static stiffness and strength and the natural frequency of the trailer girder and the central side bridge. And the trailer overturning was calculated. The research results show that the structure strength and natural frequency of the trailer can meet the design requirements. And successfully applied to a university′s towing tank, the effect is good.

 

Key words: towing tank; trailer; stiffness; strength; resonant frequency
