Abstract Details

2017, Master of Science, University of Toledo, Mechanical Engineering.
A sub-frame is a structural component of an automobile that carries suspension, exhaust, engine room, etc. The sub-frame is generally bolted to Body in White(BIW). It is sometimes equipped with springs and bushes to dampen vibration. The principal purposes of using a sub-frame are, to spread high chassis loads over a wide area of relatively thin sheet metal of a monocoque body shell, and to isolate vibration and harshness from the rest of the body. As a natural development from a car with a full chassis, separate front and rear sub-frames are used in modern vehicles to reduce the overall weight and cost. In addition, a sub-frame yields benefits to production in that subassemblies can be made which can be introduced to the main body shell when required on an automated line. The objective of the project is the design, analysis and optimization of Rear Sub-frame considering the modal analysis and natural frequency of the system using Altair Hypermesh®, Optistruct®, RADIOSS® and Altair HyperView®.
