USE OF LOW DENSITY MATERIALS IN ROADSTER BICYCLE FRAME By Iqbaljit Singh,Production

Abstract
Finite element analysis is method for analyzing complex structures by dividing geometry into small interconnected elements. In FEM, the structural system is modelled by a set of appropriate finite elements interconnected at points called nodes. As there are thousands of elements and nodes resulting in generation of large number of mathematical equations to solve the problem which can only be done with computer software, out of the many softwares designed for carrying out this analysis, SolidWorks Simulation is one capable of performing majority of simulations. On the period of years the design and manufacturing of bicycle frames has largely been an art, performed by skilled craftsmen, and their efforts have resulted in reliable and efficient design of roadster diamond shape frame but they have their limitations. The limitations of trial-and-error become most apparent when new materials enter the picture. In this work, design of roadster diamond shaped bicycle frame made currently of steel was analyzed by simulating standard tests (BIS 623:1993). Steel was then replaced with lighter materials Aluminium and Carbon Fibre. Aluminium frame failed the standard tests, and was modified thus resulting in a new design with taper tubes and stepped lugs. Aluminium and carbon fibre not only qualify as per BIS standards but also have much less weight.
