Abstract：

In order to improve the effectiveness and load-bearing capacity of clamping for under-rank end picker of hub forging robot in high temperature environment, the thermal-structural coupling analysis and structural optimization of under-rank end picker were carried out. First, the thermal load and static load of under-rank end picker were coupled based on finite element theory, the thermal stress distribution and the stress and strain results of the key components for under-rank end picker under coupling force field were obtained. Then, according to the obtaimed thermal stress distribution nephogram, the thermal insulation optimization design and the thermal-structure coupling analysis of each finger joint for under-rank end picker were conducted. Finally, according to the equivalent stress results for thermal insulation structure, the topology structure optimization of under-rank end picker was conducted. The numerical analysis shows that compared with the structure before optimization, the temperatures at reference nodes of the first, middle and last knuckles for under-rank end picker after thermal insulation optimization are reduced by 33.78%, 50.42% and 35.31%, respectively, and the masses of the first, middle and last knuckles for under-rank end picker after topology optimization are reduced by 38.75%, 18.63% and 26.45%, respectively, which achieve the optimization objectives of high temperature resistance and lightweight for under-rank end picker of hub forging robot.
