<p>The advantages of high efficiency,
reliability, flexibility and high power to weight ratio make axial piston pumps
popular for use in a wide variety of applications like construction and
agricultural machinery, off road vehicles and aerospace applications. However,
a major drawback which limits their extensive use in other commercial
applications is noise. One of the important components in axial piston machines
is the valve plate, which influences the transition of the suction and delivery
flows into and out of the displacement chamber. Appropriate design of the valve
plate can play a significant role in influencing the rate of compression and
expansion in the displacement chamber, and hence contribute towards the
abatement of noise in axial piston machines. Furthermore, the relief grooves in
valve plates makes them relatively less sensitive to operating conditions for
the operation of the pump. The high sensitivity of the valve plate design
towards the pressure build up in the displacement chamber and towards the noise
sources are big motivation factors towards rigorously exploring the design
space to find suitable designs to meet the objective of noise reduction. This
motivates the development of an advanced computational tool, colloquially
called 'MiNoS', where a powerful optimization algorithm has been combined
together with a novel parametrization scheme for valve plate design and a 1D
simulation model of swash plate type axial piston machines to find optimized
designs which can contribute towards noise reduction in swash plate type axial
piston machines. Furthermore, incorporation of the appropriate constraint also
helps in avoiding designs susceptible to the onset of cavitation in the
displacement chamber. A case study performed using the developed computational
tool has been shown later in this work.</p>
