【摘要】：绞车一般用于升降或平拖重物。液压绞车主要用在额定载荷较大的工况下,本文设计的液压绞车是用于海洋船舶工程中。液压绞车的体积较小,可以实现无极调速,换向比较容易,操纵控制简便,自动化程度高。本文所设计绞车的工况比较复杂,如果超过钢丝绳的张力范围,会威胁到人身的安全,所以本文结合液压控制技术实现恒张力控制。为了减少后期的调试次数,本文采用AMESim软件对设计绞车液压驱动系统进行仿真分析,最后得到最佳的液压驱动系统参数。本论文的主要研究内容: (1)根据液压绞车的实际工况,确定液压绞车的设计参数及要求,进行液压系统工作原理的方案设计,并对不同的设计方案进行分析论证,最终确定恒张力液压滚筒绞车机群液压驱动系统的组成及工作原理。 (2)对绞车液压系统的主要工作参数进行分析计算,确定液压系统主要液压元件的技术参数的要求,并进行元件的选型。 (3)建立液压绞车的数学模型,根据系统的传递函数分析绞车的动态特性,并对其特性进行了分析。 (4)用AMESim(Advanced Modeling Environment for performing Simulation of engineering systems)软件仿真分析液压绞车的主传动系统,得到钢丝绳的张力和速度的变化曲线图,通过调整影响张力的相关因素,得到最佳的张力响应曲线,最终确定了最佳的参数。
