摘　　要：为了确定天车升沉补偿装置关键部件补偿缸、液压马达等技术参数,基于Solidworks软件与Adams软件,建立了天车升沉补偿装置的数学模型,对天车升沉补偿装置模型进行了运动仿真,分析了天车、摇臂装置、补偿缸的运动特性,验证了天车升沉补偿装置模型的正确性。分析了被动型、半主动型天车升沉补偿装置模型的补偿效率与影响补偿效率的关键因素。研究表明,半主动型天车升沉补偿装置的补偿效率明显比被动型好,在一定范围内,天车升沉补偿装置的补偿效率随着海浪幅值的增大而增大,随着蓄能器体积的增大而增大。A mathematical model is established by the Solidworks and Adams software system in order to deter- mine the technical parameters of crown-block heave compensation device＇ s key components. The crown-block heave compensation device is simulated dynamically. The motion characteristics of crown-block, rocker arm, and compensation cylinder are analyzed and the correctness of heave compensation device model is verified. The key compensation efficiency factors of the passive, semi-active heave compensation model are analyzed. The study shows that the compensation efficiency of semi-active heave compensation model is better than passive compensation model. The heave compensation device efficiency increases with increasing wave amplitude and volume of accumu-lator.
