摘要

为研究齿轮间接触碰撞及啮合间隙等对舰炮随动系统性能及振动特性的影响，建立了考虑齿轮啮合、随动系统等多非线性因素的舰炮机电液耦合动力学模型。其中，基于改进的Lankarani-Nikravesh接触算法及齿轮间时变啮合刚度计算方法，建立了考虑时变啮合刚度的齿轮传动多体接触动力学模型。数值计算结果表明：随动系统中齿轮啮合会使舰炮的振动频率变高，降低随动系统的控制性能，但比例积分微分（proportional-integral-derivative,PID）控制器可在一定程度上抑制齿轮间接触非线性的不利影响。研究可为舰炮炮控性能的预测和优化提高提供参考。

Abstract

To study the influence of contact collision and meshing clearance between gears on the performance and vibration characteristics of the naval gun servo system, a mechanical-electrical-hydraulic coupling dynamics model considering multiple nonlinear factors (such as gear meshing, servo system, etc.) of the naval gun was established. Therein, a multi-body contact dynamic model of gear transmission was established based on the modified Lankarani-Nikravesh contact algorithm and calculation method of time-varying meshing stiffness between gears. The numerical results show that the gear meshing in the servo system will increase the vibration frequency of the gun and reduce the control performance of the servo system, but the proportional-integral-derivative(PID） controller can suppress the adverse effects of nonlinearity of contact between gears to a certain extent. The research can provide a reference for the prediction and optimization of the performance of naval gun servo systems.
