| Abstract: | Aim To study the optimization of structural dynamic characteristics of a machine gun. Methods According to the principle of mode superposition, a method of structural dynamic modification was developed with the method of sensitivity analysis based on model test results. Results Using model test and sensitivity analysis, the dynamic characteristics and sensitive points of a machine gun were obtained, and the displacement response curve was calaculated by the finite element dynamic model. Conclusion The results of calculation show that this method is correct and it can be used to improve the dynamic property of machine guns. |
