摘要
Abstract
The pitch angles of rocket assisted torpedo, airdropped torpedo, homing mine and high altitude antisubmarine torpedo will get to ±90℃when they are launched and move. At this time, the inner axis and outer axis of the vertical three-axis turntable coincide with each other to lose three-degree of freedom motion, resulting in difficulty in torpedo attitude simulation. By changing the installation mode of the sensing element and establishing corresponding driving equation of the three-axis turntable and transform formula of turntable angle and torpedo attitude angle, torpedo attitude simulation is realize when torpedo pitch angle gets to ±90℃ Theoretical analysis and experiment verify the correctness and feasibility of the proposed method. Simulation results show that this method can be used for semi-hardware-in-loop simulation of rocket assisted torpedo in vertical launch and water-entry, and it can also be used for many moveable objects with pitch angle ±90℃.ili关键词
