Passive Suspension of a Working Machine Horizontal Platform

Abstract:

The paper deals with a dynamic analysis of a passive suspension of a working machine horizontal platform and the two configurations of its suspension system. For the individual alternatives the mathematical models are formulated. The rigid horizontal platform is excited in two perpendicular horizontal directions by kinematic excitation, which was acquired by an experimental measurement of the displacements of the working machine cabin. For the arbitration of which configuration is better two criterions were considered. The first criterion was the effective displacement in two perpendicular directions of the suspended horizontal plate and its rotation around the vertical axis. The second criterion was the effective acceleration of the horizontal plate in two perpendicular directions and the angular acceleration around the vertical axis. The numerical simulations shown that the first alternative (marked as A) gives better results in the reduction of vibration.
