Title Dynamic Characteristics Analysis of an automatic machine

Abstract

On the battlefield today,the artillery is still an effective weapon to suppress the enemy.In order to support the artillery sustained high speed and steady operation,the continuous improvement of the ammunition transmission technology is particularly critical.The transmission mechanism of the artillery automatic mechanism is composed of the annular unit, the linear unit,the sector unit, the torsion unit and so on.According to the requirements of the subject,the structural design of the linear transmission unit and the sector transmission unit have been completed.Using the drawing software, the 3D modeling of the linear transmission unit and the sector transmission unit have been completed.And the software has been used to complete the simulation of the model.The next,the dynamic characteristics of it has been analyzed.At the last,the ultimate goal of simple animation has achieved.
