摘要
分析SSI效应对风电机组支撑体系的影响,介绍了地基动刚度的两种计算方法.研究了风机支撑结构考虑SSI效应的前提条件,基于质量-弹簧-阻尼模型对地基与基础的接触问题进行研究,得出SSI效应的分析方法及注意事项.
The effect of SSI on wind turbine support system is analyzed;and then two calculation methods for dynamic stiffness of foundation are described.The preconditions for considering the SSI effect of the wind turbine support structure are studied.The contact problem between the foundation and foundation is studied based on the mass-spring-damping model.Finally,the analytical method of SSI effect and the matters needing attention are obtained.
