摘要
为解决多点柔性工装系统在薄壁件装夹过程中采用密集支撑占用较多资源和调配时间问题,运用有限元法研究了工件在自重和吸附装置吸附力作用下基本体单元的布局优化方法,总结出基本体单元的阵列布局越密集整体变形量越小,且在第7次优化(布局)之后变形波动幅度小于5%;对其中的最优布局(布局)研究了基本体单元间距对整体加工变形的影响,得出间距越大对加工变形控制越有利。研究结果为更有效的解决柔性工装系统基本体单元分布的优化问题和加工变形控制提供了依据。
To solve the problem multi-point flexible fixture system adopt intensive support to clamp thin-walled workpieces is taking up more resources and allocate time.Study on layout optimization method of basic unit under the effect of gravity and adsorbability by finite element method.Sums up the matrix layout of the basic unit is more intensive ,the global deformation is smaller,and deformation range changes less than 5% after the seventh optimization （ layout ） ;It analyzes the effect of basic unit spacing to machining deformation for the optimal layout （layout ）,it shows that the greater spacing, the better to control the machining deformation The results of the study provide the basis is more effective to solve the flexible fixture system the optimization of basic unit layout and the control of machining deformation control.
