摘　　要：[目的]为了研究船用齿轮传动-推进系统的动态响应特性及影响规律,开展一系列台架试验。[方法]首先,搭建包含跨接齿轮箱的双轴齿轮传动-推进系统试验台架;然后,开展齿轮箱体及推进轴系的加速度响应测试,对比分析转速、驱动方式、轴向静推力、螺旋桨模拟轴向动态激励力等因素对系统动态响应特性的影响。[结果]试验结果表明:振动加速度响应在齿轮传动-推进系统中的传递规律以啮合频率及倍频为主,部分工况在30~80 Hz的低频段也存在峰值。[结论]研究结果可为齿轮传动-推进系统的减振降噪设计提供技术支撑。[Objective]In order to study the dynamic response characteristics and influence laws of a marine gear transmission-propulsion system,a series of bench tests is carried out.[Methods]First,a biaxial gear transmission-propulsion system test bench including a cross connection gear is built.Experiments to test the acceleration response of the gearbox body and propulsion shaft system are then carried out,and the influence of speed,driving mode,axial static thrust,axial dynamic excitation force from the propeller and other factors on the dynamic response characteristics of the system are compared and analyzed.[Results]The experimental results show that the transmission law of the vibration acceleration response of the gear transmissionpropulsion system is mainly at the meshing frequency and its multipliers,as well as peaks in the low frequency band of 30–80 Hz under certain working conditions.[Conclusion]This study can provide technical support for the vibration and noise reduction design of gear transmission-propulsion systems.
