摘要
车载DVD机芯基座与压碟臂轴配合结构对吸入式DVD的结构稳定有重要影响。首先对压碟臂轴与基座孔的配合进行了理论分析,然后应用有限元方法对过盈连接和压碟臂轴受力进行了分析。与传统算法相比,这种方法具有准备简便的优点,可为车载DVD结构设计提供可靠的理论依据。
The mating structure of mobile DVD mechanism base and disk-pressing-arm axis has a great influence on the structure stability of suction DVD.The theoretical analysis of mating structure is done firstly in this paper,then interference jointing and stress analysis of the disk-pressing-arm axis is done using the finite element method.Compared with traditional calculation method,the proposed method has advantages of accurate and quick,and can be a reliable theoretical support for structure design of mobile DVD.
