Abstract

In vibration fundamentals, the analysis of vibration spectrum is necessary to determine the characteristics of failure occurrences by using proper software. Vibration monitoring is one of the methods to obtain such data responses for the analytical assessment. Some of these monitoring methods use a transducer such as accelerometer to capture the behavioural responses. However, in monitoring vibration spectrum, there are such cases results with consequences which is known as vibration transmissibility. This study is to conduct an experimental assessment in order to analyze the performance and effect of different sizes bicycle tire on its vibration transmissibility on a Mountain Bike to the human body. Uniaxial magnetic based accelerometers were used to capture the behavioural responses for the analysis of its vibration transmissibility responses of different sizes tire. The assembly of accelerometers is fabricated on a bracket made at the suspension fork shaft and at seat post shaft. Mountain Bike was used as a test subject for the suppression of these tires at a certain distances within certain time interval experimented. The method of the study is made through assembly of accelerometers on the brackets fabricated, through BNC cables as a connection towards signal analyzer then towards task processing device with installment of vibration spectrum analysis software. The implementation of vibration transmissibility equation as a determination of the transmissibility was employed. The vibration spectrum obtained was compared and analyzed coherently on the use of different width of tire but same diameter at a constant pavement surface and constant speed. From this experimental studied, the vindication of the performance and effect of different sizes bicycle tire on its vibration transmissibility on a Mountain Bike to the human body has been made and this could assess other researcher on the study of tire performances in terms of vibrational responses.
