-
摘要: 鱼雷动力试验中, 由于被试对象结构复杂、关键参数多、试验时间长, 所产生的试验数据对分析环境提出了较高要求。为了有效消除通用分析软件处理多通道数据的劣势, 满足鱼雷动力试验数据的分析研究需求, 同时兼顾开发成本与开发效率, 编译了一套全新的处理系统。该系统从动力舱段试验特点出发, 采用LabVIEW为开发平台, 通过MATLAB混合编程技术, 创新性地实现了双坐标与归一化显示功能, 显著改善了多通道数据的读取效果。最后以真实试验数据为样本测试系统性能, 结果表明, 该系统能够满足设计要求与工程需要, 验证了系统的有效性和稳定性。Abstract: For torpedo power test, because of complex structure, multiple key parameters and long testing time of the tested object, the analysis of test data demands stricter environment condition. In order to effectively eliminate the disadvantages of general analysis software in dealing with the multi-channel data, a torpedo power test data processing system is compiled, which takes the balance between development cost and efficiency into account. Considering the characteristics of power section test, MATLAB hybrid programming technology is adopted to develop double coordinates and normalized display function in LabVIEW, thus the read effect of multi-channel data is significantly improved. Finally, the system performance is tested by actual test data, and the result shows that the system meets the design and engineering requirements with effectiveness and stability.
