Vibration Isolation Failure Analysis and Dynamic Characteristic Optimization of NVD Mecha Based on ALGOR


Article Preview

The purpose of this paper is to improve the NVD optical disk driver performance in combined sound system. Based on the optical valley of China-Wuhan R&D (research and development) red HD-NVD mecha system application, structural dynamic characteristics of the optical disk driver main parts and vibration isolation system can be analyzed by the multi-physical analysis software, ALGOR. Obtain the various modal parameters of vibration isolation system provides a solution of the unstable problem of the optical disk driver working performance which due to the low frequency vibration audio system. It is theoretically showed that the secondary vibration isolation system is feasible and laid the foundation for the optimization design of vibration isolation system.
