人字齿轮振动模型的解算方法

Solving methods of herringbone gear′s vibration pattern

对人字齿轮传动装置振动模型的解算方法进行了分析讨论 .从中得出在齿轮传动系统振动模型中 ,从参数的确定到模型定量的求解 ,经常不得不采用有限元计算方法 .对于齿轮箱体的分析模型 ,只能采用有限元法建立 ,而对于齿轮的固有振动特性的确定更是离不开有限元方法 ,因此齿轮箱的振动特性的求解除了试验方法之外 ,有限元法应作为基本方法 .

This paper analyzes the solving methods of the herringbone gear′s vibration theoretical analysis patterns. From the gearing system vibration pattern can be drawn a conclusion, the finite element calculation method must be applied from determining of parameter to its quantitative solving. For the gearbox analysis pattern, only the finite element method can be used. What′s more, determining of the gears vibration features much depends on the finite element method, therefore, the finite element method is the basic approach besidesexperiment methods of the gearbox vibration features.
