摘要
为提高仿真分析效率,缩短出具仿真分析报告的时间,探索桥式抓斗卸船机的参数化建模与仿真分析技术。文中探讨模型简化与单元选择方法及坐标系选择技巧,研究有限元模型和边界条件的参数化方法,开发出一套仿真分析系统。以某台待进行服役安全评估的老旧卸船机为例,验证参数化建模与仿真分析的有效性,并对计算结果进行了分析。对比显示,采用参数化仿真比用传统仿真方法节约了70%的时间,对于提高安全评估市场竞争力具有积极的意义。
To improve the simulation analysis efficiency,shorten the time of issuing the simulation analysis report,the paper introduces the parametric modeling and simulation analysis technology of the bridge grab ship unloader,analyzes the model simplification,unit selection methods,and how to select coordinate system,studies the parametric method of the finite element model and boundary conditions,and develops a simulation analysis system. With an old ship unloader to be subject to in-service safety evaluation as an example,the paper verifies the effectiveness of the parametric modeling and simulation analysis,and analyzes calculation results. It＇s shown through comparison that the parametric simulation can save70% time of the traditional simulation method,contributing to improving the competitiveness of safety evaluation in the market.
