Based on research of the antenna assemble procedure , the simulation model of the reflector is set up and error modeling and simulation of position of stick holes , grid bar acrossing the hole and rms of reflector face are achieved 在分析柵格天線裝配過程基礎上,建立了其反射面裝配的仿真模型,并對柵支板中心圓孔位置誤差、柵條穿人誤差和柵面誤差進行了建模與仿真計算。
A precision force banacing accelerometer for ineration navigation application is developed . the resolution , low - sensitivity threshold and high thermal stability are considered as design parameters . in order to guarantee a low - sensitivity threshold while maintaining robustness against shock , push - pull type long flexures are used in this paper . to improve thermal stability , this paper discusses the use of electromagnets as a magnetic fied source . the silicon pendulum assembly and modified inducance type pick - up is also developed to reduce assembling procedure . the measure range of accelerometer is 0 - 70g 加速度計的分辨率、靈敏度閾值和高的熱穩(wěn)定性是設計時主要考慮的參數(shù)。本論文中使用推?挽式長撓性結構來保證低靈敏度閾值,同時保證抗振魯棒性。為了提高熱穩(wěn)定性,本文中討論了利用永久磁鐵作為磁場源;微加工技術被引入擺組件的結構設計和利用力矩線圈作為激勵線圈來簡化電感式的檢測裝置。
