Abstract: A novel analysis method based on the history of multi-step stamping is proposed to analyze the structural strength of metal part accurately and reasonably. This proposed method combines multi-step stamping forming and structure analysis together: the metal blank is multi- step stamped simulation using Abaqus/Explicit to obtain the shape (thickness), residual stress of stamped parts firstly and hardening material; then the non-uniform thickness shape and residual stress obtained are used in subsequent structure strength analysis with hardening material using Abaqus/Standard. Taking elliptical cylinder part of electron component as an example in this paper, its strength is analyzed using above proposal method for reasonable and accurate simulation 锛 Keywords: Abaqus, Co-simulation of explicit and standard, Multi-step drawing forming, Mapping residual stress, Strength analysis 1. 寮曡█ 褰撳墠鐢靛瓙浜у搧鍏锋湁鏇存柊鎹唬蹇€佸紑鍙戝懆鏈熺煭鐨勬椂闂磋姹傦紝瀵圭數瀛愪骇鍝佺殑閽ｉ噾闆朵欢杩涜 寰幆 鈥滀慨鏀?瀹屽杽鈥濈殑浼犵粺璁捐鏂规硶闅句互婊¤冻鐜颁唬璁捐瑕佹眰锛屽厛杩涚殑鏈夐檺鍏冩柟娉曞氨鎴愪负鏀寔 [1] 浜у搧璁捐鐨勮涔嬫湁鏁堢殑宸ュ叿 銆備絾鐩墠瀵归挘閲戜欢鐨勭粨鏋勫己搴︽湁闄愬厓鍒嗘瀽涓紝鏄妸閽ｉ噾闆朵欢 [2] 褰撴垚鐞嗘兂璁捐褰㈢姸杩涜鏈夐檺鍏冨缓妯 锛屽叾鍒嗘瀽缁撴灉鏋佷
