【摘要】 采用悬挂犁机组空间力学模型,利用贮备牵引力为目标函数,在性能、边界约束的条件下使用单纯形法和随机方向法对悬挂机构进行了多变量优化设计,获得了满意结果。为适应空间模型需要,在犁体外载表示方面提出并使用了三力三坐标分点表示法。更多还原

【Abstract】 Based on the spatial statics model of the mounted plough set and under the conditions of the performances and the boundary constraints, the multi-variable optimal design of mounted plough set was conducted using thraction force as an objective function and simplex and stochastic direction method . The satisfactory results were obtained. In order to suit the needs of the statics , a new external force rcpcrscntation of the plough (three forces-three points )was first developed and used.更多还原
