西安交通大学和西安石油勘探仪器总厂从1981年底开始,就改善SSJ-10型检波器的动态特性,提高产品质量这一课题进行了协作。经过近两年的共同研究,取得以下三篇科研成果: 1.SSJ-10型数字地震检波器输出波形失真分析; 2.数字地震检波器横向振动特性分析; 3.检波器弹性元件的强度研究。上述成果从理论分析和试验研究两个方面对检波器的假频、谐波失真与结构的制约关系进行了深入的分析研究,提出了有效的改进措施;
Since the end of 1981, Xi’an Jiaotong University and Xi’an Petroleum Exploration Instrument Factory have collaborated on the issue of improving the dynamic characteristics of SSJ-10 geophones and improving the product quality. After nearly two years of joint research, the following three scientific achievements have been made: 1. Distortion analysis of output waveform of SSJ-10 digital geophone; 2. Analysis of lateral vibration of digital geophone; 3. Research on strength of geophone . The results from the theoretical analysis and experimental study of two aspects of the detector aliasing, harmonic distortion and structure of the relationship between the in-depth analysis and put forward effective measures to improve;
