筒式磁流变联轴器结构设计及有限元分析
|
摘要
针对传统电动吊具回转机构出现冲击现象的问题,通过设计一种筒式磁流变联轴器替代传统刚性联轴器,实现对冲击效应的主动可控。针对该联轴器传动装置,从理论分析上给出主要设计方法和思路,构建出应用于该吊具的整体结构尺寸模型。同时建立了联轴器内部磁路模型,运用ANSYS软件对设计的磁路模型进行有限元分析,得到了磁流变液工作区域磁感应强度变化趋势,并对磁路结构进行优化。结果表明,通过该方法设计的联轴器磁路模型能够满足实际工程使用,优化后的异向绕组磁路模型比同向绕组模型具有更大的抗磁饱和性能,且能传递较大扭矩,为类似的磁流变结构设计提供很好的指导。
Aiming at the impact phenomena of the traditional rotary mechanism of electric hoists,a cylindrical magnetorheological coupling was designed to replace the traditional rigid coupling to realize the active control of the impact effect. Aiming at the transmission device,the main design methods and ideas were given theoretically,and the whole structure dimension model of the hoist was constructed. At the same time,the magnetic circuit model of the coupling was established,and the finite element analysis of the designed magnetic circuit model was carried out by using ANSYS software. The variation trend of magnetic induction intensity in the working area of magnetorheological fluid was obtained. And optimized the magnetic circuit structure. The results show that the magnetic circuit model of the coupling designed by this method can satisfy the practical engineering application. The optimized magnetic circuit model of the reverse winding has greater anti-magnetic saturation performance and can transmit larger torque than that of the same winding model. It provides a good guidance for the design of similar MR structures.
