Abstract:
In this article, a mathematical model is established to determine the working parameters of a hydraulic recoil mechanism, considering the characteristic parameters of the oil. The parameters considered in this study are oil compression and oil temperature. Parameters such as recoil braking force, recoil velocity, recoil length, and recoil time are calculated in the cases of incompressible oil, compressible oil, and different working temperatures of oil. Numerical calculations are applied to 85 mm anti-tank artillery. Calculation results show that oil compression mainly affects the early stages of the recoil movement of the recoil part. When considering the oil’s compressibility, the maximum recoil brake force and maximum hydraulic brake force values are 73406 N, and 61052 N, respectively – reduced by 4.3% and 5.2% compared to the case of uncompressed oil. In addition, the working temperature of the oil also significantly affects the working parameters of the hydraulic recoil mechanism. The calculation results are a reliable theoretical basis for choosing oils suitable for the harsh working conditions of the hydraulic recoil mechanism during maintenance.
