Abstract: The change in the angle and position of the swing arm during the lifting process of the handling robot also brings about fluctuations in the stress on its fixed anchor bolts. By calculating the maximum stress borne by the bolts,the bolt is checked,and the safety factor is determined to judge whether the bolt selection is qualified. Based on this,temporary measures such as pressure plate reinforcement are proposed. While considering the mathematical and physical analysis of the model,corresponding construction methods should be adopted in combination with actual working conditions to improve installation quality.

Key words: handling robot, variable stress, safety factor, strength verification
