摘　　要：旋转开合屋盖与支承结构之间相互作用明显,需要对两者进行协同分析。为了开展不同开合程度下和运动全过程中旋转开合屋盖与支承结构间的协同分析,提出了基于有限质点法的旋转开合屋盖体系协同分析方法。该方法可以同时考虑旋转开合屋盖与支承结构之间的接触碰撞与摩擦,以及驱动荷载的作用,并采用对称结构分析模型简化以提高求解效率。采用该方法对杭州奥体网球中心旋转开合屋盖体系进行了协同分析,结果表明:该方法可以较好地反映旋转开合屋盖体系不同开合程度下和运动全过程中的结构响应;相较于开启状态,该结构在闭合状态下受力更为不利;在运动全过程中,轮轨间相互作用致使振动,动力效应不可忽视;运动速度越大,结构响应振动越明显,应根据运动速度选取合适的自重荷载增大系数。The interaction between the rotating retractable roof and the support structure is obvious,therefore it is necessary to perform cooperative analysis.To conduct cooperative analysis between the rotating retractable roof and the support structure under different opening degrees and on whole moving process,a cooperative analysis method based on finite particle method was developed for rotating retractable roof system in this work.The contact and friction between the rotating retractable roof and the supporting structure was considered as well as the driving load.Besides,a simplified analysis model for symmetric structure was adopted to improve solution efficiency.The cooperative analysis on the retractable roof system of Hangzhou Olympic Tennis Center was then performed using the developed method.The results revealed that the developed method could reflect the structural response of rotating retractable roof system under different opening degrees and on the whole moving process.Compared with the opened state,the structure was more unfavorable in the closed state.The interaction between the rollers and tracks caused vibration on the whole moving process,which indicated that the dynamic effect was considerable.With the moving velocity increasing,the dynamic vibration effect was more obvious,and hence an appropriate amplification factor for self-weight load should be selected according to the moving velocity.
