EXPERIMENTAL ANALYSIS OF VIBRATION CHARACTERISTICS OF VARIOUS BRANDED TWO WHEELERS.

MECHANICAL ENGINEERING

The main aim of our project is to provide necessary solution to the adversities caused due to vibration and analyze the vibration produced in the vehicle at idle and running condition. The vibration analysis is done using vibrometer (VB8205) monitoring parameters such as vibration frequency, velocity, acceleration and displacement. The analysis is done in three different manufacturer two wheelers such as Yamaha FZ-S, Hero achiever, Bajaj pulsar. The three bikes tested are 150cc engine. The Yamaha FZ-S houses mono shock suspension in the rear and telescopic suspension in the front, The Hero achiever houses swing arm suspension in the rear and telescopic suspension in the front, The Bajaj pulsar houses nitrox shock absorber in the rear and telescopic suspension in the front. The analysis is done in two different condition of two wheeler they are idle condition and running condition. The running condition at about 40-60km/hr the readings are noted only for chassis and handlebar positions. The parameters are recorded in idle condition at positions of before suspension, after suspension, chassis, and handlebar. The readings are noted for the different parameters and the corresponding graph is plotted. The graphs are used to record the maximum, minimum and mean values of the corresponding measuring parameters. The graph for the various parameters at running condition are compare and analyzed. Finally the root cause for vibration is detected and necessary solution is provided.
