文档介绍：西南交通大学硕士研究生学位论文第1页摘要起重运输机械广泛地应用在国民经济建设的各个领域。现代科技的发展, 国内外市场的竞争,对起重运输机械的要求也日益增高,因此起重运输机械的设计计算方法需要不断地更新、充实和完善,而传统的静态分析、静态设计方法越来越满足不了设计的需求。在起重运输机械研制过程中引入虚拟样机技术可以实现计算机对起重机各机构在各种工况下随载荷变化的运行状态及随时间变化过程的仿真模拟,得到仿真输出参数和结果,以此来估计和准确推断实际运行的各种数据。论文的主要研究内容为: (1)根据起重机动力学理论,建立了门式起重机起升机构、大车运行机构与小车运行机构的动力学模型,确定了在不同工况下的动力载荷; (2)以50t一30m箱形双梁集装箱门式起重机为研究对象,以ADAMS、Ansys、 Pro/E软件平台,建立了门式起重机整机系统的三维数字化虚拟样机,并对模型进行了起升机构、大车运行机构和小车运行机构联合启、制动情况下进行多刚体系统动力学与多柔体系统动力学仿真分析,并对分析曲线数据的结果进行了分析; (3)研究了三维实体造型软件Pro/E、有限元软件Ansys和机械系统动力学分析软件ADAMS之间的数据转换接口技术,建立了门式起重机三维实体模型并对其进行载荷的施加、约束处理、和运动关系的确定。总之,本文所研究的虚拟样机技术为设计经济、可靠、稳定的高性能门式起重机提供了有力的工具和实现方法。关键词:虚拟样机门式起重机ADAMS动力学仿真西南交通大学硕士研究生学位论文第lI页 Abstract Hoisting and conveying machinery iswidely used inthevarious fieldsof national economic with thedevelopment ofmodem scientific and technological and petition athome and abroad,the requirement of hoisting and conveying machinery also raises gradually,SO design calculation method ofhoisting andconveying machinery need toberenewed,substantiated and consummated staticanalysis anddesign methods can’tsatisfy technique ofvirtual prototype instudy ofhoisting andconveying machinery can realizeemulation thattherunning state ofeach mechanism under various working conditions which ording toloadand theprocess which ording from theemulation areused toestimate andjudge differentdataofactualmovement.
