since structural analysis has been rely too much on simulation softwares which cause great computer occupation and is hard to re-develop for optimization, the research on structural optimized design of working device based on classic mechanic theory was proposed. After taking research in structural analysis, the cross-section of working device was simplified to get the maximum stress in the standard working occasion, which was included in VB programmed software called self-compiled structural analysis software(SSAS). Reliability of SSAS was verified through comparing result to ANSYS simulation. Then, structural optimization of working device had been realized with SSAS and genetic algorithm. Taking arm as an example, the result shows that: the weight is eliminated by 1.33% which is approximately 38.3 Kg. This research provides a new way for structural design and optimization of working device, which is significant to design original excavator with better quality.
