现在已经设计和制造出来了一种单轴、无陀螺的垂直指示系统,用以跟踪本地重力矢量的运动。研制的目的是要验证一下把这一系统用于造价低、可靠性高、中等精度的导航仪中去的可能性。这个系统有感应10~(-4)g 这样小的加速度能力。它仅用了一个复摆和动片作为它的敏感元件,它用石英纤维悬挂,一般使摆迥转的输入线性加速度是由动片来感受的。为了得到摆的垂直参考座标,比例信号反馈到一个转矩系统。同时给出了正比于切向加速度的输出信号。本文要讨论空军科学研究局研究计划中这个系统的设计、发展及其性能。
A single-axis, gyro-free vertical pointing system has now been designed and manufactured to track the movement of local gravity vectors. The purpose of the development is to verify the possibility of using this system in low cost, high reliability, medium precision navigators. This system has the ability to sense small accelerations of 10 ~ (-4) g. It uses only a complex pendulum and moving pieces as its sensitive components, it is suspended with quartz fiber, the general swinging input linear acceleration is felt by the moving piece. In order to get the pendulum’s vertical reference coordinates, the proportional signal is fed back to a torque system. At the same time gives the output signal proportional to the tangential acceleration. This article discusses the design, development, and performance of this system in the Air Science Research Council research program.
