Description
technical field [0001] The invention relates to the field of structural analysis in the field of industrial robots, in particular to a topology optimization method for a transition plate of an industrial robot reducer. Background technique [0002] As an important mechanical structure optimization method, the mechanical structure topology optimization design method converts the optimization problem of finding the structure topology into the optimization problem of material distribution. According to the given load case, set the corresponding objective function and constraint conditions. Perform iterative calculation with a certain optimization algorithm, and recalculate the material distribution in the specified optimization area. [0003] In the process of structural topology optimization, the deformation under a specific load is often used as the measurement index, and the static stiffness performance of the robot is one of the important performance indicators of the robo...
