针对船舶轴系法兰式无键联轴器液压安装的油压控制和液压联轴器安装后抗冲击性能的问题，以某新型船舶的法兰式液压联轴器为研究对象，基于船级社钢制海船入级规范的理论计算要求，建立法兰式无键液压联轴器的三维模型，对联轴器三维模型进行安装接触等效应力、安装油压、安装轴向推力和安装后联轴器抗冲击性能的有限元仿真计算，并且将仿真分析的结果和理论计算的结果进行对比验证分析。结果表明：当推入量达到某位置以后，由于接触边缘位置摩擦力异常增大，轴向推力仿真值和理论计算值偏差增大；在液压联轴器运行稳定的情况下，液压联轴器内套的应力小于外套，内套的薄弱环节在两端，对安装后的液压联轴器进行运行检验，发现联轴器运行的稳定性非常好。
Aiming at the problem of hydraulic control of hydraulic installation of flange non key coupling of ship shafting and the anti impact performance of hydraulic coupling. A new type flange type hydraulic coupling as the researchobject, buildingthe three-dimensional model of flange type keyless hydraulic couplings, finite element simulation calculating of contact equivalent stress、radial hydraulic pressure、axial thrust and coupling impact resistancebased on the requires of the theory calculation of steel ships of the classification, and the results of simulation analysis and theoretical analysis results are verified. The results show that when the Length of installation reaches a certain position, the axial thrust simulation value and the theoretical calculation value deviation increase due to the increase of the friction force at the contact edge position; In the case of stable operation of hydraulic coupling, the stress of the inner sleeve of the hydraulic coupling is less than that of the outer sleeve, and the weak link of the inner sleeve is in the two ends, After the installation of the hydraulic coupling to run the test, found that the stability of the stability of the coupling is very good.
