Study on the safety design of main arm mechanism in slag pot carrier

摘要

According to the new kind of the upper arm mechanism of the slag pot carrier, optimization design, simulation and experimental research are carried out, in which the combination of conventional design, three dimensional virtual design and experimental study are applied. The motion law of multi-segment arc slide way of main arm is given by means of researching the motion process of slag ladle in the main arm slide way. The functional relationship among the internal parameters of the arm mechanism, and between load force and arm movement is revealed by studying kinematics of mechanism and dynamics law of the upper arm mechanism. The finite element analysis of the upper arm mechanism is carried out to get the weak links of structure strength, and then the improvement solution is proposed. After experiments, the method correctness of optimization and design of upper arm mechanism is testified by the coincidence of the trial results and experimentation results.
