摘　　要：升沉补偿是指因海浪起伏引起作业设备产生波动而进行的补偿校正。为减小升沉补偿对象在相应方向的运动量,以电驱动海洋绞车为研究对象,介绍海洋绞车升沉补偿机理,针对电驱动海洋绞车控制系统结构,建立母船、波浪、重物等部分的运动方程,对缆绳张力进行计算并进行仿真与分析,结果表明,无论是入水前还是入水后,由于波浪和母船运动的作用,缆绳张力的动态响应都为振荡形式,对电驱动海洋绞车系统进行升沉补偿,可以在一定程度上抑制缆绳的疲劳损伤。Heave compensation is the compensation correction for fluctuations of the operating equipment caused by the heaving of waves.To reduce the momentum of the heave compensated object in the corresponding direction,taking the electrical drive marine winch as the research object,the heave compensation mechanism for the marine winch is introduced,and for the control system structure of the electrical drive marine winch,the equations of motion of the mothership,waves and weights are established to calculate,simulate and analyze the tension of the mooring rope.The results show that,no matter before or after entering the water,due to the actions of waves and mothership motion,the dynamic response of the mooring rope tension is in the form of oscillation,which performs heave compensation for the electrical drive marine winch system and suppresses fatigue damage to the mooring ropeto some extent.
