【Abstract】 Based on a nonlinear dynamic model with 3 degree of freedom of a vibratory compacting mechanism, laws governing motion of the mechanism are studied and relations of accelerations of parts with main exciting frequency, exciting forces given by oil cylinders and a mass of a pressing mechanism itself are also investigated, which is very important and very useful for development and design of road pavers.更多还原
