摘要
磁性珩磨系统由于在工作过程中温升较大,导致无法长时间稳定地加工,限制了磁性珩磨技术的应用,工作过程中的内部损耗是磁性珩磨系统发热的主要原因。建立磁性珩磨系统的模型,从温度场仿真的角度入手,对各种损耗进行计算分析,探究其变化规律及影响因素;加入水冷循环装置优化散热,并对磁性珩磨头进行设计改进,结合损耗分析对系统温度分布进行仿真;通过磁性珩磨系统温升实验,结果表明:加入水冷循环装置及改进的二代磁性珩磨头,在转速600r/min条件下,磁性珩磨系统工作的最高温度为69.3℃,满足稳定加工要求。
Due to the large temperature rise in the course of work,resulting the magnetic honing system can not be processing stably in a long time,limiting the practical application of magnetic honing technology,The internal loss during the working process is the main cause of the heat of the magnetic honing system. The model of magnetic honing system is established,and from the point of view of temperature field simulation,the calculation and analysis of various losses are carried out to explore the variation law and influencing factors;Adding the water cooling cycle device to optimize the heat dissipation,and to improve the design of the magnetic honing head,combined with the loss analysis of the system temperature distribution simulation;The results show that the maximum temperature of the magnetic honing system is 69.3℃ under the condition of speed of 600 r/min,which meets the requirement of stable machining.
