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.
