摘要:

针对门座起重机组合臂架四连杆结构变幅运动过程,基于空间运动机构的结构分析方法,提出一种脱离计算机辅助工程(CAE)前处理器的快速建模方法.重点研究组合臂架的四连杆结构有限元模型,通过从该结构几何模型中抽取模型参数,模拟在通用CAE平台上的手工建模流程,完成该结构在变幅运动过程中各幅度位置的参数化多模型建模.基于通用求解器NX Nastran,完成12-40.5/25 t某型号门座起重机的四连杆臂架结构的实例应用,验证了快速建模方法的可行性.与应用其他建模方法的系统相比,独立的快速建模系统具有建模效率高、模型质量好的优点.

Abstract:

Based on the structure analysis method of space motion mechanism, this work proposed a rapid modeling method without computer aided engineering (CAE) preprocessor for the motion-changing process of four-bar linkage mechanism of combinatorial jib in portal crane. The study focused on the finite element model of four-bar linkage mechanism of combinatorial jib. The manual modeling process was simulated on a general CAE platform with model parameters extracted from the geometric model of this structure. Then the parametric multiple modeling of four-bar linkage mechanism which was on correspondent changing location during its whole changing process was completed. With the NX Nastran solver, the practical application of 12-40.5/25 t four-bar linkage of a certain portal crane was successfully done, proving the feasibility of the rapid modeling system. Compared with the analysis systems implemented by other modeling methods, the independent rapid modeling system has higher working efficiency and better model quality.

Key words: portal crane    four-bar linkage    structural analysis    parametric modeling    general solver
