The angular velocity drifts of a gyro constitute the principol source of errors forthe long period operation of the inertial navigation system. In order to design such asystem optimally, it is uecessary to make a mathematical model of the angular velocitydrifts of the gyro which is to be used in the system. In this paper, each drift is con-sidered as the output of white noise passing through a certain linear system. By usingthe method of time series analysis, the mathematical model of the angular velocitydrifts of a three-degree of freedom gyro is identified, their parameters are estimatedand checked, employing 631 data points of angular velocity drifts both along the azimuthand horizontal directions sampled at equal time intervals. The result of this investigation shows that the angular velocity drift of the gyrocan be subdivided into two parts, i. e. a stationary stochastic process and a nonstationaryprocess consisting of random walk and linearly increasing components. This conclusionis useful for e evaluation of the performance and quality of a gyro. For inertial navigation system, the angular velocity drifts data of any gyro shouldbe taken from a group of gyros at a longer testing period. Besides, the differenceequations so obtained sometimes need to be converted into differential equations. The method of analysis used in this paper is applicable to other similar engineeringproblems.

由于陀螺角速度漂移是长时间工作的惯性导航系统的主要误差源,因此,为了对长时间工作的惯性导航系统进行最佳设计,建立陀螺角速度漂移的数学模型是必要的。本文从认为陀螺角速度漂移是由白噪声通过线性系统形成的观点出发,采用《时间序列分析》的方法,通过模型识别、参数估计和检验等步骤,对某个三自由度陀螺仪以等时间间隔所测得的沿方位和水平方向的角速度漂移各631个数据,进行了数学分析,并分别建立了数学模型。分析结果表明:此陀螺角速度漂移是由平稳随机过程和非平稳的随机游动及滑落所组成。这个结果对于评定陀螺仪的性能和质量是有用的。但是为了真正满足惯性导航系统最佳设计的需要,要求建立长时间的陀螺角速度漂移的数学模型,为此,就需要对批量生产的陀螺仪进行长时间漂移的抽样测试,获得分析所需的样本数据。另外,如果有需要,还得把离散型的差分方程化为所需的连续型微分方程型。本文所采用的方法对相当广泛的一类工程问题也是适用的。

In this article an extension of Woodward's computational method in aerodynamics is given for the solution of an unsteady 3- motion of certain fishes. The extension is: 1. The normal velocity of the body is taken into consideration. 2. A varied vortex sheet is used instead of the uniform one. The problem is reduced to fixing a set of vortex sheet, and the whole motion can be determined then.Two examples are given. One is the sudden starting of a rectangular wing, and the other is the induced motion of a wavy...

In this article an extension of Woodward's computational method in aerodynamics is given for the solution of an unsteady 3- motion of certain fishes. The extension is: 1. The normal velocity of the body is taken into consideration. 2. A varied vortex sheet is used instead of the uniform one. The problem is reduced to fixing a set of vortex sheet, and the whole motion can be determined then.Two examples are given. One is the sudden starting of a rectangular wing, and the other is the induced motion of a wavy elliptic wing. The calculated results seem good and reasonable.The method in this article can be applied in the engineering desiga, such as design of "Anti-rilling Fins".

本文对一种鱼类的三维不定常运动提出了一个计算方法。此方法是计算飞机气动力时常用的Woodward方法(定常运动)的一个发展。不同处主要在两个方面:1)物面边界条件:除原有的法向速度外,还要考虑鱼翅本身运动(周期运动)的法向速度分量。2)计及尾涡的变化,尾涡面除原有均匀分布的分量以外,还有周期变化的分量。整个问题以涡的形式来处理。求出涡的分布,则运动的所有参数均可积分得到。 作为例子,本文计算了有攻角的矩形翼的突然起动和椭圆翼的扑舞运动。前者所得的涡量分布和二维平板翼的压力分布相同,由此可知计算方法无误。而由后者计算所得的物理图象与实际是符合的。 本文所发展的方法可以应用在设计“减摇鳍”等一类工程实际问题中。
