Design And Analysis Of A New Gun Barrel Cleaning Device

As a traditional main firepower weapons, artillery has been a great deal equiped in the ground force. The gun barrel is an important part of the auto-guns. Its function is to give a muzzle velocity of the projectile and target shooting to enable artillery completing combat. The maintenance of the gun barrel has a crucial role in improving the accuracy of fire and effecting the life. Therefore, it is proposed to clean the leftover such as copper and nylon on the abdominal wall of artillery.In order to change the traditional gun barrel cleaning system that can be pulled or pushed only by hand, we develop a new cleaning system, which is controlled by scissors mechanism and gear wheels. It can move automatically toting the bore brush equipment. The automatic cleaning system can reduce manpower. The cleaning device should be lightweight, quick, easy to operate. This design makes device automatic adjust radial dimension according to artillery bore. It can be applied in all kinds of caliber artillery. Some research has been carried out on the design and characteristic analysis of a new cleaning device for gun barrel. The major research effects include the following:1. Aim that the requirement of maintenance and some problem in cleaning gun barrel, the design requirements and index is presented in this paper. Overall design and various functions module design methods are given, including design of fix device, mode of Rotational and expansionand driving method. The mechanical structure of this set was designed and optimized. All parts were modeling by three-dimension software, in which the action collision test was operated also.2. The design blue print was made based on the sketch of transmission system. The operation principle and driving principle of the mechanism is introduced. Then,it designs and analysis the fix device. The key parts of scissors mechanism were made design and analysis. After the mechanical structure design, the working condition of the set was mad analysis and the suitable motor was found.3. For the space scissors mechanism, the forward and inverse kinematics analysis was made. The kinematical model of the whole set was built, and the emluator was made to make sure its kinematical model was correct. The dissertation presented a cute mathematical model for the further dynamical control design, and made a good effort in the development of cleaning device.4. The paper expounds the relative theory of modal analysis. Using large-scale current finite element software ABAQUS, the paper analyzes natural frequencies of the space scissors mechanism, and draw some useful conclusions from the which come out from the experiment modal analysis.
