This paper presents numerical results of boundary shape and topology optimization problem for a three-dimensional arm design of linear elastic continuum with respect to minimization problem of volume under a mean compliance constraint. For boundary shape optimization, a program using a spring-loaded traction method was used. The spring-loaded traction method was proposed as an improvement of the traction method in convergence and a procedure for determining the velocity of the domain variation by solving a displacement of a pseudo-elastic body defined in the domain with distributed spring on boundary by the loading of a pseudo-external force in proportion to the negative value of the shape gradient. For topology optimization, a commercial program combining the topology optimization method based on the homogenization method and the basis vector method was employed. From the results of analyses for a three-dimensional arm design problem by the two kinds of optimization programs, it was demonstrated that there was the case that the only topology optimization obtained limited result.
