Abstract:
This paper
describes the study on the metering shock and vibration
characteristic and its transmission from cylinder to swash plate
within a 25SCY14-1B axial piston pump. The exciting force and
torque acting on swash plate were derived and finite element
method was used to analyze the vibration model of the swash
plate in the pump. The cylinder pressure transients and swash
plate vibration were measured by miniature pressure sensor and
acceleration meters. The analyzed result was verified by
experiments. And on these bases, some principles for reducing
piston pump's metering vibration and noise were given.
Key words:
