This book presents a study on the vibrations of multistage gear trains. A tractor gearbox with four reduction stages is used as a case study. In order to have quiet and reliable gear trains for automobile and machinery power trains, it is important to optimize the designs based on the gear design parameters which can be easily changed at the design stage, when the cost of redesign is still low. The study presented is based on numerical simulations in which a general code was developed in Fortran Programming language and validated using experimental data obtained from research conducted at the...

This book presents a comprehensive methodology of modeling the interaction of mechanical and hydraulic dynamics of a hydro-mechanical multi-body system using the relatively new bond graph tool. A low duty excavating manipulator with three degrees of freedom is used as a case study. Bond graph method is chosen as the modeling tool because, firstly, it is a domain-independent graphical method of representing the dynamics of physical systems. Therefore, systems from different engineering disciplines can be described in the same way. Secondly, the available literature shows that the...
