Abstract
Article describes modeling processes influencing the lines in rods load truss of the bridge crane in Mathcad system: for the rods of the top belt of a truss; for the rods of the bottom belt of a truss; for diagonal and vertical rods of a truss at various section of the load truss; algorithm and a program complex for automation of modeling and graphical representation influence lines and maximum their values. The proposed modeling procedures of the influence lines in any section of a load truss make it possible to reduce time and cost for these calculations’ performance at least in ten times and to carry out the research on load truss parameters, rods parameters and materials change effectively.
Highlights
Computer modeling intended for decision of the diversified problems are receiving more and more propagation [1-14]
Wide use of computer modeling especially at the earliest stages of products, processes and systems creation allow to reduce in many times huge losses at the stages of cycle life
The maximum and minimum values of internal efforts in every rod of a bridge crane truss each section in a tabular form n:=1..N
Summary
Computer modeling intended for decision of the diversified problems are receiving more and more propagation [1-14]. Wide use of computer modeling especially at the earliest stages of products, processes and systems creation allow to reduce in many times huge losses at the stages of cycle life. The article describes process of influence lines’ computer modeling in various forms: analytical; program and graphic in any section of the load truss determining their maximum and minimum values of internal efforts
