Upon analysing helical spring by using the finite element method, calculation of element matrices of spring elements enables to perform efficient analysis by using the established treating method. To obtain the element matrices, however, comparatively troublesome calculation such as derivation of a shape function is required. In order to analyse spring characteristics practically by applying the finite element method, laborious calculation in the course of deriving the element matrices must be reduced. This paper, therefore, describes in detail computerized symbolic manipulation for deriving the matrices from the shape functions of helical spring element to practically improve the finite element analysis for spring elements. In addition, the example of programing by REDUCE is shown, taking into account the present state in which a programming method for compzterized symbolic manipulation in not known well.
