基于焊接结构疲劳寿命与焊接工艺设计一体化

Based on the Fatigue Life of Welded Structures and Welding Process Design Integration

摘要: 本文基于BS、IIW等标准，用VC.NET和MS-SQL开发工具设计开发了一套焊接结构疲劳寿命估算与工艺设计集成系统，实现了分布式的工作平台，从而为设计人员协同设计提供一个好的设计平台。实现了应力疲劳寿命分析和应变疲劳寿命分析、多通道多载荷疲劳寿命估算、对于无实验数据时S-N曲线估计及疲劳寿命估算。实现了IIW标准、BS标准、焊接参数管理等功能。

Abstract: In the welding fatigue estimation, International Institute of Welding Standard and British Standard are widely used. The welding structure fatigue and welding process parameter integration system are developed by vc.net and MS-SQL tools. By using the structure of clients and servers, the system provides the distributed platform. So, users can use it in different design platforms. The paper realizes the stress fatigue life analysis, the strain fatigue life analysis, the multichannel and multi-load fatigue life estimation, the no s-n curves estimation and the fatigue life estimation. The paper also realizes International Institute of Welding Standard, British Standard and the welding parameter management.
