摘要
船舶推进轴系负荷测试是轴系安装过程和检验过程中不可缺少的环节,通过有效的检验方法,检测中间轴承以及主机的主轴承所承受的实际负荷是否在理论计算允许的范围之内。本文介绍了基于顶举法的轴承负荷测量原理、测量过程和计算方法。经过实船数据的测量计算,并与应用电阻应变片法测量数据比较和分析,说明该方法在船舶推进轴系负荷测试的可行性和经济性。
The load measurement of marine propulsion shafting system ＆ an indispensable link in installation and inspection process. The actual bearing load of the intermediate bearings and main bearing within or within-out the allowed range of theoretical caleulation is checked by using effective testing method. Based on the hydraulic jack method, the measurement principle, measw＇ing process and calculation method are discussed After measurement and calculation for an actual ship, the result is compared and analyzed with measuring data by strain gauge method The results show that the method is economical and feasible in the load test of ship propulsion shafting.
