英文摘要：

Aiming at the problem of the optimization design on the hydraulic excavator attachments,the research about the attachments＇ lightweight under the condition of bucket digging was put forward. A method of using the ISIGHT optimization platform to comprehensively integrate Solidworks and ANSYS was introduced to conduct an integrated optimization on the static model of hydraulic excavator attachments. Adopted the hybrid optimization strategy of the combination between global optimization and gradient optimization to intelligently explore the design issues,and continuously selected new initial values to conduct a automatically simulation and optimization. The results indicate that this method can not only use ISIGHT optimization software to automatically search the optimal solution to meet the attachments performance requirements,but on this basis,can further reduce the overall volume of the attachments,and achieve the aim at the attachments＇ lightweight,which provides some references for practical applications.
