Equivalent Conicity Calculation Program

Equivalent Conicity Calculation Program Equivalent Conicity is a parameter that is used when investigating dynamic interaction between railways vehicle and track. The parameter describes behavior of contact between wheels and rails for straight and large radius parts of track. Calculated parameters The program calculates the next parameters: § Contact points position. § Rolling radiuses difference depending on displacement of wheel set. § Contact angles and their difference depending on displacement of wheel set. § Equivalent Conicity. Calculations are made in accordance with EN 15302. System...

Equivalent Conicity Calculation Program Work with program Once the program is started the main window emerges. The tab Wheel and Rail profiles displays wheels profiles (red color) and rail profiles (blue color). Profiles files have to be placed in the Data folder, in the same directory with Equivalent Conicity.exe program. Preparations for calculation Parameters for calculation Parameters setting panel is placed in the left part of main window. It is necessary to fill corresponding fields with wheel set and track parameters. Rail inclination should match the illustration below. Result file parameter...

Equivalent Conicity Calculation Program Parameters for protocols In the same panel is a group of parameters used only when generating reports: Input data files By default, the program uses profiles files placed in the folder Data, in the same directory with Equivalent Conicity.exe program You can show other ways to files and download them into program by Load button.
