Problems solved by technology
However, in order to solve the problem of limited spatial deflection capability of parallel mechanisms, an optimization algorithm is usually designed from the theoretical structural parameter model, and the optimal structural parameter value is obtained through the optimization algorithm, and engineering structural parts with similar values are selected according to the optimal structural parameter value , where, because the discretization characteristics of the structural parameters of the engineering structural parts are not considered in the process of selecting the engineering structural parts through the optimization algorithm, the rotation space of the parallel mechanism guided by the above method in the actual engineering design and manufacture cannot achieve the expected effect
