【摘要】：橋式起重機(jī)是國(guó)民經(jīng)濟(jì)建設(shè)中廣泛應(yīng)用的一種重要的起重設(shè)備。隨著科學(xué)技術(shù)和經(jīng)濟(jì)建設(shè)的飛速發(fā)展，產(chǎn)品用戶不僅對(duì)橋式起重機(jī)本身性能的要求越來(lái)越高，還要求盡可能縮減設(shè)計(jì)研發(fā)周期，以便取得較好經(jīng)濟(jì)效益。同時(shí)，隨著計(jì)算機(jī)技術(shù)的廣泛應(yīng)用和迅速發(fā)展，尤其是CAD技術(shù)與繪圖軟件的普及應(yīng)用，機(jī)械產(chǎn)品的設(shè)計(jì)在大程度上主要依靠開(kāi)發(fā)出來(lái)的軟件來(lái)完成，雖然目前設(shè)計(jì)中運(yùn)用的軟件已從最初的二維轉(zhuǎn)向了三維，但是這些軟件還不能滿足產(chǎn)品的系列化設(shè)計(jì)的要求，不能快速的進(jìn)行參數(shù)化的設(shè)計(jì)。這就要求對(duì)軟件進(jìn)行適當(dāng)?shù)亩伍_(kāi)發(fā)，開(kāi)發(fā)出專業(yè)的設(shè)計(jì)和分析模塊，以便快捷的對(duì)機(jī)械產(chǎn)品進(jìn)行設(shè)計(jì)和修改。近年來(lái)，涌現(xiàn)出了許多先進(jìn)的現(xiàn)代機(jī)械設(shè)計(jì)方法，尤其是有限元方法，已然成為現(xiàn)代機(jī)械設(shè)計(jì)中分析和校核的首選方法。為了提高橋式起重機(jī)的設(shè)計(jì)水平和效率，本文應(yīng)用參數(shù)化技術(shù)和有限元分析以及優(yōu)化設(shè)計(jì)等現(xiàn)代機(jī)械設(shè)計(jì)方法對(duì)橋式起重機(jī)橋架結(jié)構(gòu)進(jìn)行了快速的、系統(tǒng)的研究。 本文運(yùn)用大型通用有限元分析軟件ANSYS，開(kāi)發(fā)出了一套基于APDL的，集建立模型、結(jié)構(gòu)分析、參數(shù)優(yōu)化于一體的專用橋式起重機(jī)橋架結(jié)構(gòu)分析模塊。在進(jìn)行此種類(lèi)型結(jié)構(gòu)設(shè)計(jì)時(shí)，可以快捷輸入或修改參數(shù)以完成不同模型的建立，同時(shí)可以對(duì)橋架結(jié)構(gòu)進(jìn)行結(jié)構(gòu)的靜態(tài)和動(dòng)態(tài)分析以及根據(jù)分析的結(jié)果對(duì)重要的參數(shù)進(jìn)行優(yōu)化，實(shí)現(xiàn)橋架的優(yōu)化設(shè)計(jì)。 運(yùn)用ANSYS軟件內(nèi)部命令和APDL語(yǔ)言以及參數(shù)化技術(shù)建立了橋架結(jié)構(gòu)的有限元參數(shù)化模型，，使得模型的建立與修改方便快捷，且不易出錯(cuò)。運(yùn)用ANSYS的二次開(kāi)發(fā)技術(shù)完成了對(duì)橋式起重機(jī)橋架結(jié)構(gòu)的參數(shù)化分析。通過(guò)云圖的顯示結(jié)果對(duì)橋架結(jié)構(gòu)的強(qiáng)度、剛度、振型及小車(chē)在運(yùn)行過(guò)程中橋架結(jié)構(gòu)的應(yīng)力分布情況等進(jìn)行分析。在此基礎(chǔ)上，通過(guò)開(kāi)發(fā)出的優(yōu)化模塊完成了橋架結(jié)構(gòu)的參數(shù)優(yōu)化。此開(kāi)發(fā)模塊不僅縮短了設(shè)計(jì)研發(fā)周期，提高了工作效率，還大大減輕了橋架的自身重量，取得了較好的經(jīng)濟(jì)效益。 本文是將設(shè)計(jì)、建模、分析、優(yōu)化于一體的研究，是現(xiàn)代機(jī)械設(shè)計(jì)方法的具體應(yīng)用，對(duì)橋架設(shè)計(jì)的快捷性和設(shè)計(jì)水平的提高具有重要意義。
[Abstract]:The bridge crane is a kind of important lifting equipment widely used in the national economic construction. With the rapid development of science and technology and economic construction, product users not only have higher requirements for the performance of overhead cranes, but also require that the design and development cycle should be reduced as much as possible, so as to achieve better economic benefits. At the same time, with the wide application and rapid development of computer technology, especially the popularization and application of CAD technology and software, design of mechanical products to a large extent rely mainly on software to complete, although the design in the use of the software from the original 2D to 3D, but these software can not meet the product the series design requirements, design parameters can not be fast. This requires the proper two development of software and the development of professional design and analysis modules for the quick design and modification of mechanical products. In recent years, many advanced modern mechanical design methods have emerged, especially the finite element method, which has become the preferred method of analysis and verification in modern mechanical design. In order to improve the design level and efficiency of overhead traveling crane, this paper applies the modern mechanical design methods such as parametric technology, finite element analysis and optimization design to make a fast and systematic research on the bridge frame structure of overhead traveling crane.
