Reinforcing design method and reinforcing device for foundation ring type wind turbine generator
The invention discloses a reinforcement design method and device for a foundation ring type wind turbine generator, and the method comprises the following steps: 1, setting a lower flange of a foundation ring as a fixed constraint, and calculating the maximum stress of the foundation ring and the transverse force of the fixed constraint; 2, a reinforcing device is arranged on the periphery of the joint of the foundation ring and the tower drum; each reinforcing assembly comprises a pulling and supporting rod; 3, calculating the pre-pressure of the single pull support rod on the joint of the foundation ring and the tower drum; and 4, the actual pressure of the single pulling and supporting rod on the connecting position of the foundation ring and the tower drum is set, and then the reinforcing device is installed on the periphery of the connecting position of the foundation ring and the tower drum, so that the pressure of the single pulling and supporting rod on the foundation ring is the actual pressure of the single pulling and supporting rod on the connecting position of the foundation ring and the tower drum. According to the reinforcing design method, the transverse displacement of the tower drum can be effectively reduced, the damage of the foundation ring to the pull supporting rod is relieved, and the safety of the wind turbine generator in the operation period is guaranteed.
本发明公开了一种基础环式风电机组的加固设计方法及加固装置，加固设计方法包括如下步骤：步骤1：将基础环的下法兰处设为固定约束，计算基础环的最大应力和固定约束处的横向力；步骤2：在基础环与塔筒的连接处外周设置加固装置；每个加固组件包括一个拉撑杆；步骤3：计算单个拉撑杆对基础环与塔筒的连接处的预压力；步骤4：设置单个拉撑杆对基础环与塔筒的连接处的实际压力，再将加固装置安装在基础环与塔筒的连接处的外周使得单个拉撑杆对基础环的压力为单个拉撑杆对基础环与塔筒的连接处的实际压力。本发明的加固设计方法，能够有效减小塔筒的横向位移，减缓基础环对拉撑杆的损伤，保障风电机组在运行期间的安全。
