【摘要】：履帶起重機以其接地比壓小、起重量大、作業(yè)高度和幅度大、吊重作業(yè)不需打支腿、可帶載行駛等優(yōu)點,愈來愈顯示其優(yōu)越性。近年來履帶起重機發(fā)展迅速。目前,履帶起重機向超大噸位發(fā)展的趨勢日趨明顯。作為履帶起重機的主要結(jié)構(gòu)件之一的車架,隨著產(chǎn)品噸位跨度的增大,外形尺寸也隨之增大,但同時受各種因素的制約,在外形尺寸不能無限增大的情況下,結(jié)構(gòu)型式也出現(xiàn)了一些新的變化。因此,對車架結(jié)構(gòu)進行有限元分析計算是十分必要的。 本文分析了車架的結(jié)構(gòu)特點,在有限元參數(shù)化技術(shù)、ANSYS二次開發(fā)技術(shù)、VB編程技術(shù)和數(shù)據(jù)庫技術(shù)深入研究的基礎(chǔ)上,開發(fā)了某履帶起重機車架參數(shù)化分析系統(tǒng)。論文的主要研究工作如下： (1)本論文根據(jù)某履帶起重機車架結(jié)構(gòu)的工程實際和產(chǎn)品的設(shè)計要求,簡化力學模型,提取特征參數(shù),確定合理的單元類型、載荷及約束條件,應(yīng)用ANSYS的參數(shù)化設(shè)計語言APDL建立履帶起重機車架結(jié)構(gòu)的有限元模型； (2)對車架結(jié)構(gòu)進行有限元分析,主要包括靜強度分析、模態(tài)分析和瞬態(tài)分析,并根據(jù)分析結(jié)果對車架結(jié)構(gòu)進行強度、剛度校核。以車架結(jié)構(gòu)的總重量為優(yōu)化目標,對車架的截面尺寸進行優(yōu)化,得到了更為經(jīng)濟合理的結(jié)構(gòu)。 (3)利用VB開發(fā)GUI界面的便捷性,研究開發(fā)了某履帶起重機車架參數(shù)化有限元分析系統(tǒng),實現(xiàn)了快速建模和確定工況下的計算分析等過程,為設(shè)計研發(fā)人員提供了快速簡便的車架結(jié)構(gòu)計算分析平臺。
[Abstract]:The crawler crane has the advantages of high weight, high weight, high operation height and large range, the lifting operation does not need to hit the leg, and can carry the advantages of carrying on the load. The crawler crane has developed rapidly in recent years. At present, the trend of the crawler crane is becoming more and more obvious to the super tonnage. As the main structure of the crawler crane, the crane is the main structure of the crawler crane. One of the frame, with the increase of the tonnage span of the product, the shape size also increases, but at the same time restricted by various factors, in the condition that the shape and size can not increase infinitely, some new changes have appeared in the structure type. Therefore, it is very necessary to carry out the finite element analysis and calculation of the frame structure.
In this paper, the structure characteristics of the frame are analyzed. On the basis of the finite element parameterization technology, the ANSYS two development technology, the VB programming technology and the database technology, the parameterized analysis system of a crawler crane is developed. The main research work of this paper is as follows:
(1) according to the engineering practice of a caterpillar crane frame structure and the design requirements of the product, this paper simplifies the mechanical model, extracts the characteristic parameters, determines the reasonable unit type, the load and the constraint conditions. The finite element model of the crawler crane frame structure is established by using the parametric design language of ANSYS APDL.
(2) the finite element analysis of frame structure is carried out, including static strength analysis, modal analysis and transient analysis. According to the analysis results, the strength and stiffness of the frame structure are checked. With the total weight of the frame structure as the optimization target, the cross section size of the frame is optimized and a more economical and reasonable structure is obtained.
(3) using the convenience of VB to develop the GUI interface, the parameterized finite element analysis system of a crawler crane frame is developed, and the process of fast modeling and determining the calculation and analysis under the working condition is realized, which provides a quick and convenient calculation and analysis platform for the design and development personnel.
