引言本文介绍为同步通讯卫星新研制的一种机械滤波器。这种机械滤波器成功地继承了以前的科研成果——采用改变振子截面形状,降低扭转波传播速度,显著地缩小振子及滤波器的体积,提高了窄带宽时机械滤波器的强度,同时,在结构、设计、调试等方面又采用了一些新的方法,从而使新研制成功的机械滤波器完全满足了同步通讯卫星对器件的要求。
Introduction This article describes a newly developed mechanical filter for synchronous communications satellites. This mechanical filter successfully inherited the previous scientific research - the use of changing the cross-sectional shape of the oscillator to reduce the torsional wave propagation speed, significantly reducing the volume of the oscillator and filter to improve the mechanical strength of the narrow bandwidth filter, at the same time, In the structure, design, commissioning and so on has adopted a number of new methods, so that the newly developed mechanical filter completely meet the synchronous communications satellite device requirements.
