摘要
本次設(shè)計(jì)在參照同類塔式起重機(jī)基礎(chǔ)上，對QTZ40型塔式起重機(jī)進(jìn)行總體設(shè)計(jì)及塔身分析設(shè)計(jì)。在塔身設(shè)計(jì)工程中，采用了有限元法對其進(jìn)行分析計(jì)算，采用了ANSYS10.0軟件進(jìn)行分析。
首先按照整機(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，主要確定了塔身的結(jié)構(gòu)參數(shù)，并按照風(fēng)載荷平行于起重臂方向，風(fēng)載荷與起重臂方向呈45度角時(shí)兩種工況分析。通過對塔身作適當(dāng)?shù)暮喕?，?yīng)用ANSYS10.0軟件建立塔身的有限元模型，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)力大小及各工況下塔身的變形撓度大小，并能演示塔身加載過程的動(dòng)畫，清晰的展現(xiàn)了各種工況下塔身的受力性能。
本次設(shè)計(jì)分析通過修改模型參數(shù)共準(zhǔn)備了三種不同方案，進(jìn)而對不同模型方案進(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)，通過對此組參數(shù)下模型進(jìn)行強(qiáng)度及剛度校核，進(jìn)而獲得塔身的最終參數(shù)結(jié)果。

ABSTRACT
Based on the design of the similar tower crane, this design is composed of the system design and the tower body design of the QTZ40 tower crane. In the tower body design progress, it has carried Finite Element Method on the analysis computation, and used ANSYS10.0 software.
According to the entire machine main performance parameters, various organizations type and the steel structure pattern have been determined. And then, the parameter analysis is carried on two different operating modes which are composed of the direction of the wind load is parallel to the lazy arm and the direction of the wind load is at a 45 degrees angle with the lazy arm. Through the reasonable simplification of the tower body, the tower body finite element model is established by applying ANSYS12.0 software, and then it’s exerted various operating modes loads, and carried on the solution. Then ANSYS10.0 software can calculate various nodes stress situation, the axial stress various units receive, and the tower body distortion size under various operating modes. Also it can demonstrate the animation in the loads-carrying process on the tower body, which has clearly displayed the stress performance of the tower body under various operating modes.
Through the revision of the model parameters, three different schemes have been prepared for the analysis comparison, which is carried on the different models. Because the stress condition and stiffness condition of different model are compared under the same operating mode, and a comprehensive analysis of the intensity and the stiffness condition is carried on, a most reasonable model parameter can be obtained. Through the intensity and the stiffness examination regarding this model, then the final parameter result of the tower body can be obtained.
