摘　　要：在导管架下水系统中,锚泊系统由单链组成,导管架和驳船的运动十分复杂,利用定步长积分法在时域内做数学模型的数值解时,不能通过给定偏移量来计算锚链的回复力。锚链和系统一样处于动力响应运动中,所以也不能根据系统的平衡位置点计算锚泊外力。分析了导管架下水系统中驳船锚链的受力特点,探讨了一种新的计算方法,动态迭代计算导管架下水系统的锚链力。编制了通用的计算程序,对一种典型的导管架下水系统进行了计算,结果表明,所算得的力与乐美龙法和经验公式的结果相吻合。In jacket launching system, the anchor system is composed of a simple chain. Since the motion of the launching system and the anchor system are very complicated in the dynamic motion- response system, the anchor tension can＇t be calculated for resolving the model equation of the launching system not only by giving the moving offset but also by the balance position of the system. In this paper, a new method is given to dynamically calculate the anchor tension on the jacket launching system, a general calculating program is workout. The calculated instance shows that the method and procedure is in good agreement with the actual launching.
