摘要: 针对水下高速航行器的设计、陆上总体性能评估、实航试验方案论证等方面需建立相应的陆上半实物仿真环境以验证其作战效能的迫切需求, 设计了一种基于声对接耦合的水下高速航行器陆上全弹道仿真测试系统, 给出了仿真测试系统的构成方法和工作原理, 讨论了包括对接换能器、对接基阵、声匹配材料、通道隔离度控制等关键技术, 通过基阵测试验证了声对接耦合方法的正确性和可行性, 实现了实验室条件下水下高速航行器全系统全弹道测试。最后通过全弹道仿真实例, 验证了基于声对接耦合的全弹道仿真测试方法在水下高速航行器全系统性能评估和弹道测试上的有效性。Abstract: For the overall performance evaluation before sea trial, it is urgent to establish a hardware-in-the-loop simulation environment on land to verify its overall effectiveness. In this study, an on-land simulation test system of undersea high-speed vehicle’s whole trajectory is designed based on acoustic butt coupling. The constitution and principle of the system are given, and the key technologies concerning such as acoustic butt transducer, acoustic butt array, acoustic matching material and channel isolation control are discussed. The correctness and feasibility of the acoustic butt coupling method are verified by the test data, then the whole trajectory simulation test is realized in laboratory condition. A whole trajectory simulation example proves that the whole trajectory simulation test technology based on acoustic butt coupling is applicable to overall performance evaluation and trajectory test of undersea high-speed vehicles.
