This paper based on a settled type of structure concerning hydraulic excavator rotary platform as the research object, use the method of finite element analysis to build the finite element model in the conditions of three typicals of representative working condition about this rotary platform. By the analysis concerning the strength and stiffness of this platform structure based on the builded model, the weak link about this structure can be find out by us. Finally , according to the optimization structure design about this device, the maximum combined stress related to the easy fatigue failure area in all working condition could be significantly reduced from 162.93MPa to 115.05MPa, decrease by 29.4 percent. Thus, the structure performance could be greatly improved on the premise of guarantee the weight of construction.
