In the daily life,the spider web covered with water drops after rain,the rope on the suspension bridge,and the wire between the two telephone poles are all in the shape of catenary,which also shows that the spatial structure of natural things follows the minimum potential energy.Principle.This thesis was established on the basis of the cooperation between the research team and Hanzhong Daqin Machinery Co.,Ltd.under the background of school-enterprise cooperation.It mainly focuses on the study of the design and calculation of the suspension cable in the travel ropeway of the catenary theory.The aim is to use modern computers for auxiliary design to obtain accurate numerical solutions,avoid tedious and complicated manual calculations,and thus improve the safety of suspension engineering.The research content in this article is mainly based on the catenary theory,taking the zip line in the aerial ropeway as the object,an improved algorithm is proposed for the iterative calculation formula of the unloaded tension coefficient proposed by Zheng Lifeng,and the GUIDE in MATLAB software is used to establish the interface for the design and calculation of the suspension cable.Write specific calculation code.The feasibility of the program is verified through engineering examples,and the visual system design of the suspension cable is realized.The specific research work is as follows:First,study and analyze the basic theory of catenary,and elaborate four classic catenary theories including catenary theory,parabolic theory,cable curve theory and perturbation method theory,and comparatively analyze the mid-flexibility coefficients of various theories.range.Taking the zipline as the object,the catenary theory is used to establish the mathematical model of the cable under no-load state.Under different known conditions,the fixed point iteration method theory and Newton iteration method theory are used to derive the iterative formula of the tension coefficient,and the feasibility of the iterative formula is verified by an example.Secondly,the catenary theory is used to establish the mathematical model of itssuspension cable under load,and the numerical solution of the load deflection and tension is calculated by the Newton iteration method;The safety coefficient and durability check formula of the suspension cable are expounded in the design process;the principle of mechanical energy conservation is used to analyze the functional changes during the operation of the zipline,and the instantaneous speed during the operation is calculated.Finally,GUIDE in MATLAB software is used to design the graphical interface of the suspension cable calculation,describe the functions of each control in detail,and write the code of the key callback function,so as to achieve the specific functional requirements and verify the relevant data through engineering examples.The above studies provide a theoretical basis for the calculation of suspension cable design in engineering in the calculation of no-load tensile coefficients under different conditions,and have a certain practical effect on the engineering design of suspension cables.
