固定器

For analysis of traditional experimental modal, hammer and shaker are often used to force the structure as the clamped-clamped beam to raise the vibration of the structure, meanwhile accelerometer is placed on the structure as a sensor, then the modal parameter could be found.

传统实验模态分析大多使用冲击鎚或激振器施加点力於结构例如固定梁，做为驱动器激发结构的振动，利用加速度计做为感测器置於结构上，以求取结构之模态参数，但传统之模态实验设备都有实验操作不易以及价格昂贵的缺点。

This paper analyzed data from multiple sources and different structures, concluded three types of info: Login info, Event info, and Packet data info, then created the formation for every type of data; In order to combine future possible new data, IDS using profile and formation string together, create and practice data formation standard algorithm; Because in the collected data, there is info that is redundant or has minor effect on the IDS, this paper discussed the rules of redundant data differentiating and safe data differentiating, Then create data filter rule base; Data collecting system uses distributivity design, collecting module like a black box. we can get data which was filterd and had standard formation, if we created a new model string for new data source. Module work individually; filter data right away at the collecting node.

本文分析了多种来源的、不同结构的数据，将其总结成登录信息、事件信息和网络数据包信息三种类型，并为每种类型的数据设计了固定的格式；为了与将来可能出现的新型数据兼容，采用了配置文件与模式字符串相结合的方法，设计并实现了数据格式标准化算法；由于收集到的数据中存在冗余的信息和对入侵检测影响不大的信息，本文分别讨论了冗余数据辨别规则和安全数据辨别规则，并建立起数据过滤规则库；数据收集系统采用分布式设计，收集器以黑盒形式提供，对新的数据源只需设计一个新的模式字符串，即可得到过滤后的、具有标准格式的数据，各收集器间独立工作；在收集点即对数据进行过滤，只向分析中心报告可疑数据，以减少传输和存储的数据量，降低对网络性能的影响。
