基于Kriging模型的微夹持器优化设计
Optimization Design of a Micro Gripper Based on Kriging Model
摘要
Abstract
In order to tradeoff the opening distance,gripping force sensitivity and rapid response of a novel micro gripper,a optimization method was proposed based on Kriging model.Latin hyper-cube sampling method was used to select test points,and the response values corresponding to each test point were calculated by using ANSYS.The correlation analysis was carried out to determine the structural parameters affecting performance greatly,and the parameters were selected as the optimiza-tion design variables.The nonlinear model reflecting the relationship between the performance index and the design variables was built by using Kriging theory,and the multi-obj ective optimization model was established.The comparative analyses of the performance indexes before and after optimization show that the magnification ratio increases 7.4%,the natural frequency increases 16.46%,the output stiffness increases 9.84%,the maximum stress decreases by 5.75%.It illustrates that the proposed performance optimization method is effective.关键词
