【Abstract】 Taking a new type of prefabricated building wall panel installation machine as the research object, the mechanism configuration and specific implementation are analyzed, the kinematic and dynamic mathematical models of the boom landing mechanism are established, and the functional relationship between the maximum load of the cylinder and the scale parameters is solved. Taking the size parameters of each component of the boom landing mechanism as the design variables, taking the minimum maximum load of the boom cylinder during the boom lifting process as the objective function, and taking the overall machine layout,mechanism singularity, geometric constraints and other constraints as the constraints, the boom is established.The scale optimization model of the landing mechanism, based on the composite shape method and iterative calculation through Matlab software, the optimal scale parameters of each component of the boom lift chain are obtained, and the maximum load of the boom lift cylinder is reduced by about 11%, effectively improving the dynamic performance of the mechanism. Based on Creo software, a virtual prototype of the prefabricated building wall panel installation machine before and after optimization is established, and dynamic simulation analysis is performed to verify the correctness of the scale optimization model. This research will be used for prefabricated building wall panel installation and provides a basis for improving the performance of the machine.更多还原
