Recoil brake is one of the core components of the artillery. It plays a main buffer role in artillery firing. Its internal flow is very complex, so the traditional one-dimensional computational model can not reflect the characteristics of internal flow field fully and accurately. Two-dimensional computational model of the recoil brake with actual structure was proposed based on dynamic mesh technology. Using dynamic layering method, the movement of dynamic grid was driven by Profile file. The data of Profile file was obtained from experiment measured of artillery recoil. Simulation of the flow field of recoil brake accurately was achieved. Pressure, speed and other data were got by simulation. It also reveals the laws of liquid flow and can provide theoretical support for fault analysis and optimization design.
It takes much less than the model test and can give a detailed description of the internal details of the internal flow field of recoil mechanism that use computational fluid dynamics theory and numerical simulation do research. It has the advantages of low cost, accurate calculation, high efficiency, easy to implement and so on. This article provides a brief introduction to the current situation and development outlook of the simulation study of the recoil mechanism using of computational fluid dynamics.
