1.硬支承和软支承在引力波的作用下,弹性天线体中形成一个位移振动场(位移是时间和空间的连续函数),场中可能有若干个位移为零(不动)的点——节点.节点可以在真实的弹性体内,也可以在假想的延伸弹性体中. 为了克服地球的重力,天线在运行时必须采用适当的方式支承.理想的支承点当然是天线的节点,因为这样不会影响天线的本征频率和它的Q值.但由于种种原因,有时不得不让支承点与天线的节点有所偏离,这就必须考虑支承所引起的一些效应.本文研究支承方式对天线Q值的影响. 支承方式可以分为软支承和硬支承两类.所谓硬支承,是指在支承条件下完全不让天线中的支承点运动,这实质上是使支承点成为天线位移场中新的节点,因而也就完全
1. Hard and soft bearings Under the action of gravitational waves, a displacement vibration field is formed in the elastic antenna body (displacement is a continuous function of time and space). There may be several points in the field with displacement zero (not moving) The node can be in a real elastic body or in an imaginary extended elastic body In order to overcome the earth’s gravity the antenna must be supported in a suitable way during operation The ideal bearing point is of course the antenna node because Will not affect the antenna’s eigenfrequency and its Q value.But for some reason, sometimes have to make the support point deviate from the node of the antenna, which must consider some of the effects caused by the support.This paper studies the support of the antenna Q value of the impact of the support can be divided into two types of soft support and hard support the so-called hard support, is under the conditions of support in the antenna is not allowed to move the support point, which is essentially the support point into the antenna displacement field The new node, so it is complete
