钢筋切断机仿真设计 学生姓名：涂志军 班级： 指引教师：邢普摘 要：钢筋切断机是一种广泛应用于机械制造、建筑等行业中的重要工具，随着科技的进步和加工规定的不断提高，既有的钢筋切断机己逐渐不能适应顾客的新需求，目前钢筋切断机尚有待于进一步全面进一步的研究减少成本、增长新功能、提高自动化水平等将成为钢筋切断机此后发展的方向 针对钢筋切断机设计和生产的现状，进行了生产加工状况、常用故障及核心问题的调查，然后使用有限元及虚拟样机技术对钢筋切断机三维模型进行构造静力学分析、动力学分析，进而提出改善方案 借助先进的Pro/E, ANSYS和ADAMS软件联合仿真，建立了钢筋切断机模型，并实现了其运动仿真，通过对箱体模烈做有限元分析，提出了改善方案并证明了改善方案的可行运用LS-DYNA仿真钢筋切断机剪切钢筋的动态过程.核心词：钢筋切断机 建筑 齿轮 指引教师签名： type steel cutting machines’designing Student name:Tu Zhijun Class: Supervisor:Xing PU Abstract：The Reinforcing Steel Cutter is an important instrument used widely in the machinery manufactures and construction industries. With technologies being improved and more requires asked, users aren't content with the existing Reinforcing Steel Cutter. It needs further and deeply researching now Its directions will be reducing cost, adding new features and improving the automation level. Aim at the design and production status of the Reinforcing Steel Cutter, Study the common faults and key issues. Next, propose improvement scheme by analyzing static structure and dynamics of three-dimensional model of the Reinforcing Steel Cutter with the FEM technology and VP technology. Co-simulation by virtue of the advanced softwares Pro/E, ANSYS and ADAMS, establish a model of the steel cutting machine and achieve its motion simulation. Present improvement schemes and prove their feasibility through doing finite element analysis on the case model.
