Because the structure of the excavator’s trivet is very big, moreover the stress is complex, the working conditions are also very special, so the rigidity is often small in the work process, simultaneously the platform and trivet connect some are easy to present the phenomenon of stress concentrations. If the platform and trivet’s design is unreasonable, it will bring very serious consequence. The paper focus on this question and it carries on the optimized design of the trivet. After the improvement, we can obtain the quite ideal structure.
