摘　　要：为了评估超深水打桩锤系统的可用度,基于Markov理论提出了一种可靠性研究方法。首先,根据超深水打桩锤系统工作特点和运行机理分析系统状态,建立了可修复性系统的Markov模型,选择恰当的方法求解系统稳态可用度;然后,将可靠性维护技术引入原Markov模型进行定量分析,解得系统稳态裕度,并对系统瞬态可用度进行了对比分析,基于控制变量法分析了各转移率对系统稳态可用度的影响,为系统可靠性的优化配置提供了理论指导;最后,在MATLAB APP designer开发环境下,将系统Markov过程的分析以可视化界面呈现了出来。研究结果表明:可修复性超深水打桩锤系统的稳态可用度为0.97120746,基于可靠性维护的系统稳态可用度为0.99991434;该结果说明,经可靠性维护后的系统稳态可用度有所提高,可满足实际工程所需,可以为超深水打桩锤系统的国产化设计提供一定的理论支持。In order to evaluate the usability of ultra-deep water piling hammer system,a reliability research method based on Markov s theory was proposed.Firstly,according to the working characteristics and operation mechanism of the ultra-deep water piling hammer system,the system state was analyzed,the Markov model of the repairable system was established,and an appropriate method was selected to solve the steady-state availability of the system.Then,the reliability maintenance technology was introduced into the original Markov model for quantitative analysis,the system steady-state margin was solved,the system transient availability was compared and analyzed,and the influence of each transfer rate on the steady-state availability of the system was analyzed based on the control variable method,which provided theoretical guidance for the optimal configuration of system reliability.Finally,the analysis of the system s Markov process was presented in a visual interface in the MATLAB APP designer development environment.The research results show that the steady-state availability of the repairable ultra-deep water pile hammer system is 0.97120746,and the steady-state availability of the system based on reliability maintenance is 0.99991434.It shows that the steady-state availability of the system is improved after reliability maintenance,which meets the requirements of practical engineering and provides some theoretical support for the localization design of ultra-deep water pile hammer system.
