摘要
为了缩短舰载稳定平台类产品的研制周期,降低开发成本,方便实验研究,提出一种新型的六轴船摇模拟转台系统.从系统的组成、结构和各模块的功能角度,叙述系统实现的用途和相关性能指标.在上台体的平台台面上安装光电传感器,通过分析该转台中的坐标系及其相互之间的关系,利用坐标变换的方法详细推导了,当下台体模拟船舶在海浪中的摇摆运动时,光电传感器瞄准线实现方位稳定跟踪的数学模型.通过对仿真结果的分析,验证了所建模型的正确性.
In order to shorten the shipboard stable platform＇s development cycle, reduce its development cost and facilitate experimental research, a new type of six-axis ship swaying simulation rotationtable was proposed in the paper. The application and performance index were introduced from the system＇s composition, structure and function of each module point of view. The photoelectric sensor was installed in the body of upside three-axis platform, and the model which realizes the photoelectric sensor＇s line of sight orientation stable tracking was computed with coordinate transformation when the underside three-axis rotationtable rotated around its own axes. The analysis of simulation results shows that the orientation stable tracking model is correct.
