|
The optimized mathematical models of cylinder thrust and cylinder stroke were constructed by analyzing the work characteristics of clamping mechanism in the vertical squeeze casting machine. Then, the half of parametric model of double-toggle clamping mechanism was established by software ADAMS, and four multi-objective optimization schemes were mentioned by selecting the maximum cylinder thrust and the maximum cylinder stroke as the objective function. Furthermore, the clamping mechanism was optimized under the condition of meeting institutional constraints, and the optimal results of four schemes were compared with the initial scheme respectively. The result shows that the comprehensive optimization effect of unified objective function constructed by linear combination weighting method is the best, which makes the maximum cylinder thrust and the maximum cylinder stroke reduce to a certain extent, and the performance of clamping mechanism is improved further.
