Failure analysis of driveshaft of truck body caused by vibrations

In recent years, a current trend of mechanical engineers is to design such mechanical drives which will have a guaranteed lifetime. In this guaranteed operating life it is many times expected to be failure-free and service-free operation of a drive. The considerable problem is a condition of drive when a failure occurs during the guaranteed lifetime. Consequently, the identification of the failure is processed. Regarding the complexity of the drive, the failure identification is often difficult and it requires analytical as well as experimental procedures, methods and processes. The experimental methods are very useful for identifying the actual state of individual drive components, or to verify the utility of proposed solutions. The mentioned methods are difficult, especially for time-consuming and the need of technical equipment is required. On the other hand, the analytical procedures could be used mainly in experiment preparation phase and after the experiment realization; it means at the design stage of review procedures or during preparing new solutions. The issue being dealt with in the present article focuses mainly on the experiment stage. This paper deals with identification of excitation of vibrations causing the failures of driveshaft of truck body. From results analysis the authors found that a source of vibration is particularly main exciting frequency of the combustion engine. As becomes clear from the character of the combustion engine, it is necessary to take measures to reduce vibration.
