Simulation study on the dynamic similarity of oil-liquid spring recoil mechanism
Source abstract
Abstract
This study focuses on the oil-liquid recoil mechanism of a specific artillery system, deriving the dynamic similarity and similarity constants of physical quantities for the device. By altering boundary conditions, a comparative analysis was conducted using the original and similarity models. A comprehensive simulation of linear dynamic similarity during the operation of the entire system model was performed. Through a comparison of the recoil force data between the similarity model and the original model, it was observed that both exhibit consistent trends and a proportional relationship, with the maximum recoil force of the similarity model being 15% of that of the original model. Further comparison of the similarity coefficient and normalized root mean square error values demonstrates that the similar and test model data exhibit good fitting and similar trends. This study validates the accuracy and effectiveness of the research method for the similarity model of the recoil mechanism in artillery with spring-liquid recoil dampers.
