Free Vibration Analysis of Differernt Materials under Crack as a Cantilever Beam
Journal Title: International Journal for Research in Applied Science and Engineering Technology (IJRASET) - Year 2017, Vol 5, Issue 4
Abstract
A simple and unified approach is presented for the vibration analysis of a cantilever beam. Natural frequency and damping ratio are calculated with an experimental process. Estimating damping still remains as one of the biggest challenge in structure made of different materials like brass, stainless steel and aluminium. All materials or structures posses certain amount of internal damping, due to which energy is either dissipated into heat or radiated away from the system. Internal damping includes the 10-15% of the total damping in system. The primary objective of this thesis is the free vibration analysis of different materials under surface cracks to estimate the effect of cracks on damping ratio and natural frequency. The beams of different crack size were pressed up to 30 mm and signals were catches by VIBSCANNER with the help of accelerometer attached at the free end of cantilever. Omnitrend provides Frequency response (FRF) graphs after processing data imported from VIBSCANNER. Damping ratio is determined by half-power bandwidth method. It is observed that damping is increased with increasing crack size for all materials and is minimum in aluminium when compared to brass and stainless steel. The effects of surface cracks and material parameters on the natural frequencies are investigated through this experimental study.
