ME I6200 Mechanical Vibration
This course is the first course in Mechanical Vibration and includes developing equations for a single-degree-of-freedom system [SDOF] model based on concepts such as equivalent mass, stiffness and damping. Laplace transform approach is used to obtain response due to initial conditions, sinusoidal forced or base excitation and rotating unbalance. Vibrations under general forcing functions such as periodic inputs and nonperiodic inputs also studied using frequency response function and convolution integral respectively. Above mentioned approaches are modified and used to investigate multi-degree-of-freedom system (MDOF). Modal analysis is introduced to find natural frequencies and mode shapes. As an application of MDOF un-damped and damped vibration absorbers are introduced to reduce resonant vibrations. The use of MATLAB software in vibration analysis is emphasized.
