Embodiment Construction

[0021] The method of the present invention will be further described below in conjunction with specific embodiments:

[0022] Step 1. Use ANSYS software, AutoCAD software and APDL language to import the 3D model of the ring rail crane into SAP2000 software. The specific process is as follows:

[0023] The first step is to code the 3D model of the ring rail crane through the APDL language and save it as a file named F.txt;

[0024] The second step is to use ANSYS software to create a new file and save it in ANSYS, open the F.txt file in the first step through the read function in ANSYS software, and then run the F.txt file to generate a new text file and save it as a file A file named S.txt;

[0025] The third step is to open the S.txt file in the second step through the read function in the ANSYS software, and then delete all the spaces in the S.txt file through the search and replace function in the ANSYS software, and then select the S.txt file All commands in and copy;

Abstract

The invention discloses a method for automatically calculating a counter weight in a circular track type crane, which comprises the following steps that codes of a three-dimensional model of the circular track type crane are written by using an APDL language, so that the three-dimensional model of the circular track type crane established in AutoCAD software is smoothly imported into SAP2000 software, and finite element analysis is performed on the three-dimensional model of the circular track type crane. The three-dimensional model of the circular track type crane is initialized and loaded by adopting simulation setting in SAP2000 software, and the bearing reaction of each hinge point at the counterweight end in the three-dimensional model of the circular track type crane is calculated through a finite element algorithm, so that the weight required by the counterweight of the circular track type crane is calculated. According to the method, the problems that the counter weight calculation process of the circular track type crane is complex and the accuracy is not high are effectively solved, the finite element analysis technology of structural analysis and design software is utilized, and the actual counter weight of the circular track type crane is obtained by carrying out practical configuration on a three-dimensional model of the circular track type crane through a computer; and the safe and reliable operation of the circular track type crane is ensured.

Description

technical field [0001] The invention relates to a method for calculating counterweight in a ring-rail crane, in particular to an automatic calculation method for counterweight in a ring-rail crane. Background technique [0002] As more and more enterprises, factories, logistics, warehouses, and yards use cranes, the projects are becoming larger and larger, and the requirements for the lifting capacity of the cranes are getting higher and higher. The ring-rail cranes came into being. In order to ensure the environment The stability of the overall system of the rail crane and the quality of the counterweight are also increasing. In actual operation, the staff often apply a large counterweight, sometimes even exceeding the load that the structure can bear, to ensure the safety of the lifting work, but excessive counterweight will increase the difficulty of the crane structure design. The steel structure of the crane causes irreversible fatigue damage, which not only leaves a s...
