摘要
分析了船舶总体弯曲变形对沿船体纵向布置曲柄摇杆机构的机架尺寸所造成的伸长和缩减 ,并在深入研究机架尺寸缩减对曲柄摇杆机构极限摆角和最小传动角影响的基础上 ,提出了适用于沿船体纵向布置曲柄摇杆机构极限摆角和最小传动角的一组计算公式 ,最后以实例计算验证了船舶总体弯曲变形对曲柄摇杆机构极限摆角和最小传动角的影响程度。
The authors of this article make analysis on the effect of total bending deformation of the ship on the dimension change of the frame in a longitudinal crank rocker mechanism. On the basis of deeper researches on influence of the dimension change of the frame on the limiting swinging angle and the least transmission angle of the rocker in a longitudinal crank rocker mechanism, this paper introduces a group of formula for calculating the limiting swinging angle and the least transmission angle of a crank rocker mechanism arranged along the longitudinal direction of the ship. Verification has carried out on the extent of influence of the total bending deformation of the ship on the limiting swinging angle and the least transmission angle of the rocker in a longitudinal crank rocker mechanism through the use of a concrete example.
