可控震源振动器平板多频响应分析
Analysis of multi-frequency response of vibroseis vibrator baseplate
摘要
Abstract
High precision and broadband excitation is the main development tendency of vibroseis . Through the engineering application ,there are differences in the response of vibrator baseplate at different scanning frequency ,which result in the output signal of vibroseis is inconsistent in the whole frequency and restrict the development of vibroseis .Therefore ,it's necessary to analyze multi-frequency response of vibrator baseplate .According to the basic theory of finite element method ,the finite element model of KZ-28 vibroseis vibrator was established ,the dynamics re-sponses of vibrator baseplate at different frequency was carried out and response rule of vibrator baseplate was mastered .It was found by analysis that insufficient rigidity of vibrator baseplate was the most fundamental reason which brought about the different performance of vibrator base-plate at different frequency .This study has a positive effect for design and optimization of vibrator baseplate .关键词
