The objective of this study is to present a dynamic model of a backhoe-loader including cab dynamics in order to simulate the vibration levels transmitted to the operator. For this purpose, analytical solutions of the cab and the machine are developed by deriving the equations of motion of the system and the state space forms of the solution are implemented in the commercially available simulation software, MATLAB/Simulink. In addition to the analytical solution, a model is developed using the physical modeling toolboxes of MATLAB/SimMechanics. Cab model developed in SimMechanics is extended to simulate whole machine dynamics by inserting machine body and tire parameters. Vibration data is acquired from the machine for experimental validation of the models. Analytical and SimMechanics solution are evaluated by comparing the seat acceleration results for the same inputs. Furthermore, simulation results obtained from the models and the measurement results are found to be in agreement in both time and frequency domain.
