Abstract : the attitude error performance of electrostatic gyro should be understood and the relevant error equations must be set up in order to ensure the navigation precision of esgm. the relation between the navigation errors and the attitude errors of gyro was derived by use of spherical triangle. the simulation results show that the temporal performances of the longitudinal and distance errors which come from the initial alignment errors are periodically variational. they also show that the longitudinal and distance errors resulted from gyro drifts are not convergent in time. thus, the effects of initial alignment errors and gyro drifts can not be neglected and must be estimated and compensated
文摘:為了保證靜電監控器的導航定位精度，需要了解靜電陀螺的姿態誤差特性，建立相應的誤差方程.本文採用球面三角形原理推導了導航定位誤差與陀螺姿態誤差的關系式.模擬結果表明，由初始定向誤差引起的經度誤差和距離誤差的時間特性是周期變化的；由陀螺漂移引起的經度誤差和距離誤差是隨時間發散的.因此，初始定向誤差和陀螺漂移的影響不能忽略，必須對其進行估計和補償 -

Four parameters for determining the type of circuit of spherical four - bar linkage are defined. according to the relationship of these parameters, three types of circuit of spherical four - bar linkage are found, which is proved in view of geometry point. base on the theory of sphere triangle, an approach of identifying the circuit and branch defect of spherical four - bar linkage is proposed
首先提出了四個迴路類型判斷參數，根西安理工大學博士學位論文據這些參數之間的關系，將球面4r機構迴路分為三種類型，並從幾何的觀點進行了證明;然後基於球面三角理論，提出了球面4r機構迴路及分支缺陷識別的轉角符號法，而由空間第一組機構與其等效球面4r機構迴路特性的等效性，此方法對空間第一組機構的迴路和分支缺陷的識別同樣有效。 -
