Abstract:
Multi-body dynamics w ith its applicat ion in the vibrat ion reduct ion for antiaircraft gun is studied in this paper. The gun dynamic model is set up in w hich uninterrupted fire act ivit ies, dynamic response and constituent properties are considered. The dynamic properties of the gun system w hich are est imated f rom the sof tw are compiled f rom majority operat ions are simulated. T he results analyzed by numerical simulat ions show that the barrel. s vibrat ions caused by uninterrupted f ire are obv iously cut dow n by raising up the inert ia moment for recoi-l ing parts and alternating the location of the barrel prot rusion, w hich can reduce the gun tube muzzle disturbance. The conclusion is made to increase the gun fire accuracy and guide the gun st ructural design.
