A hydraulic breaker is one of the attachments for smashing work which installed at the end of excavator arm. There have been many studies for improving the performance of the hydraulic breaker as the use of the hydraulic breaker is increased. However, this paper focus on optimally designing to minimize the weight of a hydraulic breaker housing. Design points to generate meta-models are obtained by using an orthogonal array and an evolutionary algorithm is used for optimization. The weight of the hydraulic breaker housing is found to decrease from 664㎏ to 632㎏.
