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 -
The kinematic performance of the macpherson suspension on a real vehicle is studied, and the changes of the front wheel alignment and the motion of the front wheel in the longitudinal and the transversal directions are figured. based on the requirements of general layout, a constrained optimization design model is set up with the steering cross rod ball joint position as the optimization variables ( design parameters ), and the sum of steering cross rod length interference while the left front wheel turning and bouncing as the objective function. and the optimization results are worked out by programming on computer
針對一種實際車型上的麥弗遜式懸架，計算分析了轉向輪跳動時前輪定位角和車輪橫向、縱向滑移量的變化情況，並根據實際車型上麥弗遜式懸架的空間布置要求，建立了以轉向橫拉桿斷開點空間位置坐標為優化變量，轉向橫拉桿斷開點空間布置坐標可變化范圍為約束條件，車輪轉向和跳動時轉向橫拉桿長度干涉量為目標函數的約束優化設計模型。 -
