Material Selection for Computer Aided Design Software for Crankshaft Design

A crankshaft contains two or more centrally-located coaxial cylindrical ("main") journals and one or more offset cylindrical crankpin ("rod") journals. The design of the Crankshaft considers the dynamic loading and the optimization an lead to a shaft diameter satisfying the requirements of Automobile’s specifications with cost and size effectiveness. Microsoft visual studio package was used in the development of this software, which is capable of designing the shaft with reference to its easy interface, being an open system and its ease of file formats acceptability. It was used during the entire cycle of this software development (analysis phase, design phase and implementation phase). The developed Software was able to design the crankshaft taken into consideration the dimensions and the materials used; it will automatically generate the shape after the input of the expected configuration. The Software was able to select the materials to be used in the Crankshaft design with its properties and loading conditions incorporated. Consequently, the problems encountered in manually shaft design which is majorly design error, repetitive drawing and, or iteration when changes are to be made, can be overcome if the various advantages, utilities and flexibilities which modern high – speed micro – computers offer are put into good use in the design of shafts.
