【摘要】 弹簧是重要的机械零件之一，作为一种具有弹力的机械元件，它广泛用于各种机电装置中。随着机械技术的进步，弹簧的种类越来越多，对弹簧的要求也越来越高。传统的弹簧设计理论已经不能满足竞争日益激烈的弹簧工业发展的需要。随着计算机技术、计算机辅助设计技术、优化技术和有限元分析技术的进步，这些现代设计方法已经在弹簧的设计实践中获得越来越多的应用。本文以圆柱螺旋弹簧为研究对象，基于MATLAB、Pro/toolkit和APDL语言对弹簧进行了优化设计、参数化建模及参数化有限元分析。首先，介绍了优化设计理论及圆柱螺旋弹簧的优化设计方法，建立了优化设计数学模型，并借助MATLAB的优化工具箱和图形用户界面开发环境GUIDE创建了圆柱螺旋弹簧的优化设计系统，实现了圆柱螺旋弹簧优化设计的高效、便捷化。其次，研究了利用Pro/Toolkit程序开发技术进行Pro/E二次开发的通用方法，应用参数化建模方法及Program技术创建弹簧模型。利用Pro/Toolkit，借助Visual C++集成环境，开发了参数驱动程序，实现了弹簧的参数化建模，提高了弹簧模型的建模效率。最后，介绍了ANSYS二次开发技术。用ANSYS的内部命令和APDL语言以及参数化技术建立了弹簧的有限元模型，运用ANSYS的二次开发技术实现了弹簧的参数化分析。使得采用有限元分析分析弹簧的建模、计算工作简单、方便、快捷。本文的研究工作实现了圆柱螺旋弹簧的优化设计、参数化建模及分析，对现代设计方法在弹簧设计中的应用和普及具有重要意义。更多还原

【Abstract】 Spring is one of the important mechanical parts,as an elastic component, it is widelyused in all kinds of mechanical and electrical devices. With the advancing of mechanicaltechnology, new types of springs have been emerging, and the requirements towardssprings have been becoming severed. The traditional spring design theory can no longermeet the demands of the spring industry that is developing in a increasingly intensecompetition. With the progress of computer technology, Many modern design methodssuch as CAD, optimal design technology and finite element analysis technology areapplied widely in the pratical design of springs.In this paper, cylindrical helical springs is taken as the research object.Based onMATLAB and Pro/toolkit and APDL, the optimal design and parameterized modeling andFEM analysis of the springs are implemented.First of all, the theory of optimal design was introduced and the optimal designmethod of the cylindrical helical spring was analyzed in this paper, established themathematical model of optimum design. An optimization design system of the cylindricalcoil spring was created with the optimization toolbox of MATLAB and GUIDE, whichcan optimize the spring design parameters efficiently.Secondly, the method of procedure development technology to carry on secondarydevelopment in Pro/E using Pro/Toolkit was studied in this paper. By applying theparameterized modeling method and program technology to aims to create springmodels. The parameters driver was developed under Visual C++ developmentenvironment to realize parametric modeling of the spring so as to improve the springmodeling efficiency.Finally, the secondary development technique of ANSYS was analyzed. By the usageof ANSYS internal command and APDL language as well as parametric technology, thefinite element model of the springs was established, and the parameter FEM analysis ofsprings was relized. This made it to be convenient and efficient to establish the springsFEM models and perform FEM analysis of springs . The study of this paper realized optimal design, parametric modeling and analysis ofsprings, it is important and meaningful to the application and popularity of modern designmethods in the aspect of the spring design and analysis.更多还原
