摘要
本次設(shè)計(jì)在參照同類塔式起重機(jī)基礎(chǔ)上,對(duì)QTZ40型塔式起重機(jī)進(jìn)行總體設(shè)計(jì)及吊臂的設(shè)計(jì)。在吊臂設(shè)計(jì)工程中,采用了有限元法對(duì)其進(jìn)行分析計(jì)算,采用了ANSYS10.0軟件進(jìn)行分析。
按照整機(jī)主要性能參數(shù),確定各機(jī)構(gòu)類型及鋼結(jié)構(gòu)型式,主要確定了吊臂的結(jié)構(gòu)參數(shù),并按照吊臂端部加載、跨中加載及根部加載三種工況分析。通過對(duì)吊臂作適當(dāng)?shù)暮?jiǎn)化,應(yīng)用ANSYS10.0軟件建立吊臂有限元模型,施加各工況載荷,進(jìn)行求解,進(jìn)而可得各工況下各節(jié)點(diǎn)受力情況及各單元所受軸向力、軸向應(yīng)力大小及各工況下吊臂的變形撓度大小,并能演示吊臂加載過程的動(dòng)畫,清晰的展現(xiàn)了各工況下吊臂的受力性能。
通過修改模型參數(shù),對(duì)不同模型進(jìn)行分析比較。由比較不同模型在相同工況下的受力狀況及剛度狀況,綜合分析強(qiáng)度和剛度條件,可得出受力最為合理的一組模型參數(shù),通過對(duì)此組參數(shù)下模型進(jìn)行強(qiáng)度及剛度校核,進(jìn)而獲得吊臂的最終參數(shù)結(jié)果。

Abstract
Refers to the similar tower crane, this design is composed by the system design and the lazy arm design to the QTZ40 tower crane. In the lazy arm design progress, it has carried Finite Element method on the analysis computation, and used ANSYS10.0 software.
According to the entire machine main performance parameter, various organizations type and the steel structure pattern has been determined. The design parameter of operating modes which are composed of nose increase, the cross center increase and the root increase. Through the suitable simplification to the lazy arm, the lazy arm finite element model is establishment applied ANSYS10.0 software, and then exerted various operating modes load, carried on the solution. Then ANSYS10.0 software can calculate various pitch points stress situation, various units receive the axial stress size, and the lazy arm distortion size under various operating modes. Also it can demonstrate the animation in the process of the lazy arm increase. It has clearly displayed the lazy arm stress performance under various operating modes.
Through the revision for model parameter, the analysis comparison is carried on the different model. Because the stress condition and rigidity condition of different model is compared under the same operating mode, and the generalized analysis intensity and the rigidity condition is carried on, a most reasonable model parameter can be obtained, though the intensity and the rigidity examination regarding this model, then the final parameter result of the lazy arm can be obtained.
Key words: QTZ40 tower crane Lazy arm Finite element analysis ANSYS10.0
