Optimization Design of Load Ratio between Bearings in Rational Alignment of Propulsion Shaft Considering Propulsion Force

  • 摘要: 目前没有计入推力的影响或者计入推力时推进轴系的轴承负荷法校中的计算方法没有实现艉管前后轴承的负荷比在1/2~1/3的范围内,为此提出了计入推力和不计推力的弯矩时满足艉管前后轴承的负荷比最佳的轴系合理校中设计方法。对旋转时的轴线进行优化设计,并对一个简化轴系模型进行校中计算。计算结果显示:没有考虑推力影响时艉管前后轴承的负荷比小于1/3,计入50%额定推力时,推力减轻了艉管后轴承的载荷压力,艉管前后轴承的负荷比在1/2~1/3的范围内,且全轴系的轴线是曲线,后轴承对设计基准直线轴线的偏离量较大。
