The influence of the temperature change on the force in the hydraulic brake of the artillery system
Апстракт
Hydraulic brake is an important part of the artillery system because reliable amortization of
energy of the recoil parts depends on its functioning. Therefore, it is important to estimate time-dependent
pressure field inside the brake which depends on many factors, such as geometry of the brake parts,
velocity of recoil parts and physical characteristics of the oil that is used in the brake. During recoil and
counterrecoil process of the recoil parts of the artillery system, heating of the oil and the other parts of the
hydraulic brake occurs. In this paper the influence of the temperature change of the hydraulic brake parts
on the recoil force is analyzed. Since the hydraulic brake assembly is axisymmetric, the problem is
considered to be two-dimensional. Differential equations that describe flow field in the brake are solved
numerically using CFD software. A comprehensive comparison between numerical and experimental
results has been performed and good agreement is observed.
