Abstract

The idea of harnessing combustion to perform mechanical work is by no means a new one. The internal combustion engine, as we know it today, has its origins in the last century, however the idea for controlling combustion to perform mechanical work dates back to the Renaissance. Even with the advent of alternative sources of power for commerce and personal applications, the internal combustion engine represents a large portion of the power generation available in this country.There are numerous types of internal combustion engines, each with a variety of subsystems. While all of these types and corresponding subsystems are equally important, this investigation is focused on the valve train dynamics of a pushrod type internal combustion engine. Operating this type of engine at too high of an engine speed usually causes dynamic malfunctions such as spring surge, lifter/cam pair separation, valve bounce, etc. in the valve train. Although the interaction of each of the valve train components contributes to the limit speed, the shape of the cam plays a critical role. This cam shaft along with cams are designed in CATIA V5 and we analysed the cam shaft in ANSYS using various materials and determined which material is best for cam shaft.
