Abstract:The period of the piston motion of hydraulic impact mechanism was divided into three stages.and a non-dimensional parameter-the accelaration ratio β was also generalized. And then a series of formulae describing the mechanics and the kinetics of the piston were derived, which Provided a new approach for designing and studying the hydraulic mechanism and new theoretical bases for further research.
