Iron tower support material processing method

Abstract

The invention discloses an iron tower support material processing method, and the method is closer to the reality than traditional methods, is simpler to operate than theoretical analysis, and enables calculation results to be closer to facts under the premise of increasing tiny complexity. The method comprises the following steps of: (1) calculating the maximum internal force of each stressed material component under a plurality of using conditions by utilizing a finite unit method calculation tool; (2) loading a prescribed percentage of the maximum internal force of a supported component onto a support point in a direction vertical to a supported rod according to an engineering design requirement, so as to construct a model; (3) for the model, calculating influences, on a support rod, of a support force P1 by using a finite unit method, so as to obtain an internal force of the support rod; (4) obtaining minimum specification and number of bolts required by the components according to the calculated internal force; (5) substituting the calculation result back into the model and accurately determining and optimizing a boundary condition; (6) judging whether the calculation result is changed or not, if the judging result is positive, skipping to the step (1), and otherwise, executing step (7); and (7) successfully carrying out optimization and ending the operation.

Description

technical field [0001] The invention belongs to the technical field of iron tower design in power lines, and in particular relates to a processing method for iron tower auxiliary materials. Background technique [0002] The ultimate goal of the calculation of the auxiliary materials of the tower is to ensure that the auxiliary materials have sufficient strength to support the normal work of the stressed materials and are the lightest in weight, so that the structure can be as economical as possible while meeting the design standards. [0003] The so-called auxiliary material refers to an auxiliary component that bears no or almost no force in the structure under the action of external forces (power lines, wind, ice, etc.), and mainly plays a supporting role for other components. [0004] Corresponding to the auxiliary material is the stress material. The so-called force material is the load-bearing member in the structure under the action of external force, but its length is...

Problems solved by technology

However, this method is complex and not universal, and improper model design or improper parameters are likely to cause excessive deviations in calculation results.

Therefore, it is not practical in actual production and is only used to write design specifications
