摘要
起重机是现代工业在发展生产过程自动化、机械化，改善物流运输为前提，提高劳动生产率必不可少的器械设备。自改革开放以来，我国经济一直持续飞涨，许多公司和工厂对于设备的自动化程度要求也越来越高，与此相适应的起重机技术也在飞速发展，起重机功能与类型不断增加，使其使用规模也越来越广。
针对在门式起重机的传统设计流程中，参与人员更多的依靠经验、拼凑和手工劳动等方法，导致了设计产品设计的周期较长，设计质量相对较差，设计成本高，产品缺乏市场竞争力等不足。为提高门式起重机起升机构设计的效率和质量，提出了对门式起重机的咽喉设备即起升机构进行研究，改进其结构使其更加合理，使其使用更加方便，并且设计成本更加低廉的优化设计方案。起升机构主要用来对重物进行提升或下降以完成运输，是任何起重机所必须的部分，因而是起重机最重要、也是最基本的机械机构。考虑到其具有短暂、重复、周期性循环的运动特点进行针对性的起重机起升机构的优化设计。主要应用UG等三维绘图软件进行结构分析，并且对其结构进行运动仿真。得出其基本的结构与运动规律后，再针对性的对其卷筒部分进行ANSYS静力学分析，在保证其约束条件及可靠性下对其卷筒的体积与质量进行最小的优化。从而得出起升机构的优化组合。 [资料来源：www.doc163.com]

Abstract
Crane is a essential modern important mechanical equipment in the realization of the production process mechanization, automation, improve material handling as the premise, improve labor productivity. It plays an important role in developing national economy and improving people's things and cultural life. With the rapid development of economic construction, mechanization, the level of their own initiative is also increasing, and this is also the crane skills to adapt to the rapid development of product types, increasing the use of more and more extensive.
For gantry crane lifting mechanism of traditional design, designers more depend on experience, trial and error, static, qualitative analysis and manual labor, resulting in the design product design cycle is long, poor quality of design, design of high cost, lack of competitive products, such as insufficient. In order to improve the gantry crane hoisting mechanism design efficiency and quality of the proposed gantry crane on the throat of the equipment is lifting mechanism study, improve its structure to make it more reasonable, so that the use is more convenient, more low cost optimized design scheme. Lifting mechanism is mainly used to achieve vertical lifting of materials, is an indispensable part of any crane, which is the most important and the most basic crane. The lifting mechanism includes a spreader, reel, reducer, brake, motor and other aspects. Taking into account the characteristics of the short, repetitive and cyclical cycle, the optimization design of crane hoisting mechanism is carried out. The main application of UG and other 3D graphics software for structural analysis, and the structure of the motion simulation. After its basic structure and motion law are obtained, then the ANSYS static analysis is carried out for the part of the drum, and the optimization of the volume and quality of the drum under the condition of constraint and reliability is guaranteed. So as to obtain the optimal combination of lifting mechanism.

Key Words：Crane; hoisting mechanism; 3D modeling; motion simulation; optimization design
