Abstract: In order to solve frame breaking problem of a certain beach wagon, the parameterization finite element technology was used to conduct a finite element modeling and the static intensity analysis to its frame structure in this article, and the practical improvement program was proposed, and the theory basis was provided for later similar product development. Because of parameterization finite element technology, the modeling process has ideal duplication, openness and good revision, and it reduces the product modification cycle and improves the product quality.
