Parameter Identification and Sensitivity analysis of Gun Elevating Equilibrator

doi:10.3969/j.issn.1000-1093.2020.09.005

Abstract

Abstract: In order to accurately simulate the dynamic response of the elevating equilibrator in the state of gun launch, an elevating equilibrator dynamic model in the state of gun launch is established based on the theoretical model of air-liquid mixtures of hydraulic oil， the cylinder stiffness and the structure of elevating equilibrator. ADAMS software is used to build a parameterized dynamic model of elevating equilibrator， and the parameters to be identified are established. The model parameters are identified using the particle swarm optimization algorithm based on the test data of a vehicle-mounted gun and the gun launching dynamics model. The simulated results agreed with the experimental data， thus verifying the accuracy of the proposed model and the availability of the parameter identification results. The sensitivities of the parameters of elevating equilibrator dynamic model to the pitching motion of gun were calculated．The results of sensitivity analysis show that several parameters， such as air content and initial pressure， have a large impact on the pitching motion of gun.
