摘要:
塔筒法兰螺栓联接可靠是保证风力机组安全运行的关键。通过对风力机组运行工况分析,推导出塔筒法兰面单个螺栓最大拉力的计算方法,为后续的螺栓强度计算提供参考。本文阐述了风力机组塔筒法兰螺栓2种断裂方式的断口宏观形貌,分析确定所有机型塔筒法兰螺栓的共性结构参数,基于APDL语言定制结构参数交互式输入界面,实现法兰螺栓的参数化建模、载荷施加以及求解,完成了塔筒法兰螺栓强度应力分析,提出的最大预紧力计算机制,可计算螺栓满足不同屈服强度下最大预紧力值,为螺栓的设计、选型以及现场操作人员预紧力的设定提供参考,具有重要的指导意义。
Abstract:
 It is key for safe operation of the wind turbine to have connection reliability with flange bolt used in tower.The method to calculate single flange-bolt maximum tension is presented by means of analyzing wind turbine operation condition, which provide reference for bolt strength calculation.Two fracture modes of flange bolt used in wind turbine tower is presented As well as the flange bolt structural parameter in common for all wind turbine type is confirmed.The mutual window to input structural parameter is created based on APDL language, which accomplish the parameterized modeling of flange bolt, bolt loading and solving to achieve the stress of flange bolt.In addition, the calculation mechanism for pre-tightening force which have important guiding significance to design bolt, select bolt mode and set pre-tightening value by field operator can obtain the maximum pre-tightening value that satisfy the biggest different yield strength.
