| Abstract: | In terms of the analysis of maximum stress of each telescopic boom of truck-mounted crane while working, optimum dilation of each boom is determined based on equivalent stress. The control system of each telescopic boom dilation is designed; mathematical modeling, algorithm design, performance simulation and pa- rameters matching of controller are carried out. The results of on-site tests indicate that the optimum dilation based on equivalent stress can improve the force conditions of telescopic booms of truck-mounted cranes andenhance their stability. |
