Dynamic Behaviour of a Light Trailer Chassis
In this work numerical tools of simulation are applied to analyze the structural dynamic behavior of a light trailer passing through a secondary highway. After the dynamic analysis of the rigid model is realized, the resultant forces are obtained in the points of attachment between the springs and the chassis. These responses serve as input for a global analysis of the simplified model in a finite element program, making possible the identification of the most critical regions of the structure. Next, a more detailed local model of the critical region is created in order to evaluate singular stress concentration points. This method named global-local serve to obtain detailed results on structural analysis through a reduced number of elements. These results supply important information to the designer, making possible that modifications in the design can be best realized to improve the performance of the product.
