This paper discusses a new method of the fast starting of gyrocompasses, that is, the observer theory and principle of pole-placement through state feedback are applied in the fast starting of gyrocompasses on fixed and moving base. And serveal nonlinear effects and errors of the system are anal ysed. The results of digital simulations show that the fast starting time of this method on fixed and moving base is less than a half of that of the original method.

术文研究了一种新的电控陀螺罗经的快速启动方法,即采用状态观测器,通过状态反馈实现极点配置,使陀螺罗经快速启动。文中讨论了陀螺罗经在静基座和动基座上的快速启动方法,对系统的各种非线性效应及误差作了分析。数字仿真结果表明:采用此法后,电控陀螺罗经在静基座上的快稳时间比原来缩短了一半以上;罗经在动基座上的快稳时间可减少到半小时以内。

The tie-down of shipboard-helicopters is a key problem which concerns the link between the shipboard-system and the helicopter-system.It is different from the tie-down of ground and it is based on moving. Under the severe weather condition the airframe must support big load factor along all directions. So it is very important whether the airframe and tie-down equipment have high carrying ability.The features of tie-down are moving base, carrying ability in one direction of tie-down equipment and nonlinear relation of load-displacement of landing gears. In this paper, these special problems are handled reasonably and effectually; "Matrix method of force" and "Matrix method of displacement" are used, respectively, in calculating loads of tie-down equipment and stress of the airframe of the helicopter.The result is satisfactory compared with the test result.

舰载直升机的系留问题是舰、机双系统联系的关键。与地面系留的不同在于舰载系留是基于运动着的基础。特别在高海情下,机体承受各个方向的过载,且载荷较大。这样,机体结构及系留索具是否有足够的承载能力,就显得异常重要。 运动着的基础、系留索具单向承载性以及起落架承载与变形的非线性关系构成了舰载系留的特点。本文针对这些特殊问题,进行了合理而有效的处理。分别采用了“矩阵力法”及“矩阵位移法”进行系留索具的载荷和机体结构应力的计算,并与实验进行了对比分析,得到了满意的结果。
