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。
In order to solve the problem that the multi-point flexible tooling system uses intensive support to occupy more resources and allocate time during the process of clamping the thin-walled parts, the layout optimization method of the basic body unit under the self-weight of the workpiece and the adsorption force of the adsorption device is studied by the finite element method , The conclusion is drawn that the densities of the deformations of the elementary unit arrays are less than 5% after the 7th optimization (layout), and the more intensive the array layout of the basic body units is, The impact of the overall processing deformation, the greater the distance between the deformation control of the more favorable. The results provide a basis for solving the optimization problem of basic body unit of flexible tooling system and controlling deformation effectively.
