Analysis of the influence parameters on the pressure field in the hydraulic brake
Апстракт
The pressure change in time in the hydraulic brake of the automatic cannon depends on many factors such as
the geometry of the brake, the velocity of the piston, the amount of the hydraulic oil in the brake, elevation angle of the
cannon, etc. The analysis was made at the extreme values of the temperature interval of the cannon usage as well as the
normal temperature since the temperature affects the properties of the hydraulic oil. The numerical simulation of the flow
field in the hydraulic brake during recoil was performed in CFD software ANSYS Fluent. The simulation was made in a
2D numerical domain based on the flow geometry in 3D space. Due to the flow field boundaries movement during the
process, the dynamic mesh was employed. The dynamics of the hydraulic brake piston was determined using the solver
in which the forces that act on the gun are defined by the User Defined Function file. The experiment was performed by
firing from the 20mm M55 gun mounted on the stand. Expe...rimental results contain pressure change in time inside the
brake which was measured by the piezoelectric pressure sensor. The dynamic behavior of the cannon was recorded by
the high-speed camera. The numerical results of the pressure change and position of the gun deviate within acceptable
limits with respect to experimental results. Based on that, further analysis of the influence parameters on the hydraulic
brake force can be done by numerical simulation.
