Abstract: The validity and accuracy of a highfidelity mechanistic multibody model of a vertical piano action mechanism is examined experimentally and through simulation. An overview of the theoretical and computational framework of ...

Abstract: The proper orthogonal decomposition (POD) is employed to reduce the order of smallscale automotive multibody systems. The reduction procedure is demonstrated using three models of increasing complexity: a simplified dynamic ...

Abstract: The theoretical framework for constructing a fully mechanistic multibody dynamic model of a vertical piano action is described, and its general validity is established. Equations of motion are derived symbolically using a ...
