不同工况下船用斜齿轮动力学特性仿真

Simulation of Dynamics Performance of Marine Helical Gear under Different Working Condition

斜齿轮传动在船用动力装置中起着重要的调速作用,以某型船用斜齿轮传动系统为研究对象,基于Abaqus/Explicit显式有限元法,建立了斜齿轮副非线性动态接触有限元模型。对额定工况下齿根动应力进行了仿真,研究了负载转矩、中心距和润滑方式等参数对斜齿根动应力的影响。研究结果对船用斜齿轮副优化设计具有一定参考价值。

The helical gears transmission play an important role in marine power plant, taking certain type of marine helical gear transmission system as research object, the finite element model of helical gear nonlinear dynamic contact is built based on ABAQUS/Explicit dynamics finite element method （FEM）. The dynamic stress variation of helical gear tooth is simulated under rated conditions, the impact of changes in load torque, center distance error and lubrication mode on helical tooth root dynamic stress is researched. The results have certain reference value for the optimized design of marine helical gear.
