摘要
潜艇运动仿真和航行试验评估在潜艇的整个设计周期中起重要作用。在设计论证阶段,基于理论计算的潜艇运动仿真可以对潜艇总体性能进行预评估,而航行试验评估则对仿真计算与模型试验进行验证。本文介绍了潜艇运动仿真的设计状况、设计要点及系统辨识方法。并对标准海上试验程序提出修改意见,在确定的定常航行条件下,这个新的程序可以在较少的时间内获得更有用的结果。
Modeling of submarine motion and evaluation of sea trials play an important role within the design cycle. During early stages of the cycle simulations of submarine motion based on theoretical calculations allow the evaluation of sea trials plays a crucial role in acceptance and as a tool to validate calculations and model tests. This paper will start with the tools for submarine motion simulation, their present part in the design process and future goals for improvement. This is followed by a short introduction to system identification tools, illustrated by the planned evaluation of the sea trials of one foreign submarine. Finally a modification of one of the standard sea trials is presented. The new procedure for the determination of the so-called neutral level flight condition will give more robust results while needing significantly less time.
