Static and Vibration Analysis Of Backhoe Loader Chassis

Abstract

Construction industry is undoubtedly the backbone and propelling force behind our progress. In response to booming construction industry, utilization of earth moving equipment has increased considerably leading to high rate of failure. Backhoe Loader chassis is the skeleton of a commercial vehicles. The main function of the truck chassis is to support the different components like engine, cabin, transmission, front axle and rear axle. So it is necessary to analyze chassis to avoid failure while it is in working condition. Computer simulation techniques provides a great leverage in design optimization for weight reduction, better material utilization, shorter design cycles and elimination of major part of prototype testing. Static analysis of the chassis shows the equivalent stress and deformation contour when Backhoe Loader is in working condition. From static analysis, high stress area can be found out when Backhoe Loader is in different load condition. Also by providing some design changes, stress can be minimized. From the modal analysis different natural frequency of vibration and deformation pattern at each natural frequency can be found. It is necessary to find natural frequency of the structural component in order to avoid resonance phenomenon. In order to have vibration response at different location of the chassis, harmonic analysis is carried out. From this analysis the vibration pattern at different location can be observed. Hence by providing necessary change vibration level transmitted to the operator can be optimized.
