摘要
Abstract
To establish the accurate and efficient flexible barrel model with the influence of external loading taken into consideration,a modelling method of flexible barrel was presented by introducing the virtual substance into the barrel system, and the constraint equation of virtual substance and the multi-body dynamics equation of barrel were derived. Taking a tracked selfpropelled artillery for an example, the multi-body model of the barrel was introduced, and then the comparative curve between the experimental data and the calculation result under the same firing condition was obtained. The comparison shows that the effect of the external loading can be described by this flexible barrel model, such as the bullet contact force. The disturbance of gun muzzle and the elastic vibration of the barrel can be accurately calculated by this model.关键词
