The research and analysis of vibroseis ground force coupling

When vibroseis substrate interaction with the earth, There is a certain relationship and impact between surface of the visco-elastic medium and Vibroseis earth coupling. With the theoretical study of mechanical system model, it established the spring-damper mechanical system model. This article finded the vital parameters-Substrate quality, Elastic coefficient of spring and Damping coefficient which are linked with the elastic medium from the second-order system. Using different values of the parameters obtained with the ground force vibroseis vibration model and the impact of the important links, so as to enhance the exploration and provides a theoretical basis for resolution.
