It has a lot of work to do in small arms maintenance with inefficiency. And In order to solve the problem that an information system is designed to work it out. The system is developed by C# and SQL server 2000 language. And the integrated design, software composition, data structure and technique implementation method are provided. It can increase the management scientifically, secure the weapons effectiveness and prolong the life. The system has made the weapon maintenance automatically and increased the troops operating efficiency.

Correction machine gun finite element model to predict dynamic characteristics is very important. Through theoretical calculations and experimental test structure to obtain guns frequency response function, given the sensitivity of both the correlation function and expression, introduced a model correction method, and laid the theoretical foundation for a certain type of machine gun finite element model updating. Build a certain type of machine guns and modal testing and analysis system was carried out to test the vibration frequency response function. Boundary condition parameters of the machine gun was amended, and modal test results were compared to prove the validity of the model correction method.
