摘　　要：利用Monte Carlo概率模拟方法和有限元法相结合的随机有限元法研究连续卸船机各主要结构的强度、刚度以及压杆稳定可靠性,提出一种能综合评价连续卸船机结构系统可靠性的方法,实例分析表明,该方法对连续卸船机结构可靠性设计具有指导作用。By utilizing the SFEM combining the Monte Carlo probabilistic simulation method and finite element method,the paper studies the strength,rigidity and compressed bar＇s stability and reliability of the continuous ship unloader,and proposes a method which can comprehensively evaluate the system reliability of the continuous ship unloader structure.The case analysis shows that the method can guide the reliability design of the continuous ship unloader structure.

关 键 词：连续卸船机 MONTE Carlo法 有限元法 可靠性
