Optimized Design of Mechanical Excavator trivet

Because of the structure of the excavator trivet is very big,the stress is complex,and the working conditions are also very special,the rigidity is often small in the working process,simultaneously,the platform and trivet connect are easy to present the phenomena of stress concentrations.If the platform and trivet's design are unreasonable,it will bring very serious consequence.The paper focused on this question and carried on the optimized design of the trivet.After the improvement,the quite ideal structure can be obtained.
