Influence of Random Road Surface Roughness to Servo System
2018
The gun servo system is the key part of self-propelled anti-aircraft gun weapon. In order to improve the integrated equipment support of the weapon system and form the optimal fighting capacity, it is essential to study the response of random road surface roughness to servo system. The road surface roughness as a random signal to the vibration characteristics of barrel was studied. Road surface roughness model was established by the method of white noise. Then a two-degree-freedom vibration model of base of a wheeled self-propelled gun was set up. A gun servo system was established and controlled well. Numerical simulations were presented to verify effectiveness of these models where road surface roughness was through base of wheeled self-propelled gun as inputs of servo system. The results can be utilized to research the accuracy estimation before firing.
