磁环式检波器特性与系统研究

RESEARCH ON THE CHARACTER AND SYSTEM OF MAGNETIC ANNULUS STYLE GEOPHONE

从研究磁电式检波器的特性出发,拓宽地震检波器的研究思路,研究了一种新型的磁环式地震检波器。对检波器特性矩阵、弹性件结构和系统的设计等方面进行了研究,特别是在磁路设计上采用辐向环式的永久磁钢,使其产生了一个均匀的磁场,取得了很好的效果。经过各项数据测试,使得检波器的灵敏度、失真度参数都有一定的提高,达到了设计要求。

On the basis of magnetic-electric geophone's characters, we design a new magnetic annulus style geophone, which can get a well-disposed wider magnetic field to make a great effect. In this paper, the matrix of character, the designs of magnetic circuit and flexibility system are all researched. According to the test results, the magnetic annulus style geophone is in accord with the demand of high accuracy seismic exploration.
