In the analysis of sliding base isolation, a modified continuous friction model is proposed to replace the conventional Coulomb friction model, which can avoid tracing the transient boundary between meshing and sliding and reduce the calculating error.

• 在基底滑移隔震分析中,提出了修正的连续摩擦力模型以取代传统的库仑摩擦力模型,避免了计算过程中跟踪啮合滑移的过渡边界从而可降低计算误差。
