摘　　要：本文简述了多桨船节能轴支架的节能原理,扼要介绍了一艘双桨海洋调查船和一艘三桨高速艇采用这种支架后经船模自航试验证实的节能效果:前者可节能11.9％,相当提高航速0.55kn,后者节能6.5％,相当提高航速0.9kn.The principle of energy-saving shaft bracket suitable for multi-screw vessels is briefly introduced. The results of self-propulsion tests of ship models installed with the normal and new-designed energy-saving struts for a twin-screw oceangraphical vessel and a highspeed craft with three screws are given. It has been shown that the saving in power is 11.9%(or 0.55 kn in speed gain) for the oceangraphical vessel and 6.5%(or 0.9 in inspeed gain) for the highspeed craft respectively.
