谐波传动中不同材料柔性齿轮的有限元分析
|
摘要
应用有限元法对柔性齿轮进行模态分析,研究不同材料的选取对其性能的影响。首先选取了两种典型的柔轮型号,根据其实际结构及几何尺寸利用Pro/E工具建立了柔轮的几何模型,然后将几何模型导入有限元分析软件ANSYS中,定义了三种不同材料的属性,即合金钢、碳纤维增强环氧树脂基复合材料及玻璃纤维增强环氧树脂基复合材料,对柔轮进行了模态分析,比较了不同型号及不同材料的柔轮振动特性。结果表明复合材料柔轮较钢制柔轮的振动频率有大幅提高,这类材料应用于谐波传动柔性齿轮值得进一步研究。
Using finite element methods to carry on the modal analysis of flexsplines,from which the effect on its properties of different materials was researched. Firstly two typical types of flexsplines were selected and their geometrical models were developed based on the actual structures and geometrical dimensions by Pro /E. Then the geometrical models were imported into the software ANSYS to calculate the frequencies and modal shapes. Three different materials were used to alter the individual properties of the models,which were steel and composite materials based on epoxy resin reinforced with glass fibers or carbon fibers. The vibration performance was studied for flexsplines with different types and different materials. It was showed that the vibration frequency of composite materials flexsplines was improved greatly than steel ones. So it is worth to further study that the composite materials how to used for manufacturing harmonic driver flexsplines.
