质量特性在影响万向架成像平台的稳定性方面起作用。在某种程度上，静态平衡和抖动之间的关系是预先建立的。然而，动态不平衡的定义和作用并没有被彻底理解。导致动态不平衡的讨论，我们通过使用分析手段，抖动产生的静态不平衡力，当我们遵循这些力通过隔离安装，伺服指向精度和干扰抑制系统使用一个单一的自由度模型。然后，我们将定性结果应用到探讨的惯性和交叉耦合响应的产品的一些细微差别的动态不平衡的讨论。提出了测量和校正静态不平衡量的策略和具体方法，以及减小平衡架动不平衡量的原理，以减小干扰响应，最终提高图像分辨率。最后，我们将测试一种测量和校正动态不平衡的方法，以便于未来针对抖动改善的定量测试。
Mass properties play a role in affecting the stability of gimbaled imaging platforms. The relationship between static balance and jitter, in some measure, is previously established. The definition and role of dynamic unbalance however, is not as thoroughly understood. Leading to the discussion of dynamic unbalance, we show through the use of analytical means, the jitter resulting from static unbalance generated forces when we follow these forces through the isolation mounting, servo pointing accuracy and disturbance rejection systems using a single degree of freedom model. We then apply the qualitative results to the discussion of dynamic unbalance exploring some of the nuances of product of inertia and cross coupling response. We will offer strategies and specific methods for measuring and correcting static unbalances and the principles of reducing dynamic unbalance in gimbals in order to reduce disturbance response and ultimately improve the image resolution. Finally, we will test a method for measuring and correcting dynamic unbalance to facilitate future quantitative testing aimed toward jitter improvement.
