【摘要】：舰船的生存能力研究是现代化海军舰船设计核心内容之一。生存能力是舰船及其各系统在自然环境中遇到事故、海损或在作战环境中遭受损伤时,保持或最大限度恢复其航行、作战等技术的能力[1]。尤其是在现代海战中,舰船一旦破损进水,如果不能有效抗沉,将直接威胁其战斗力和生存能力。如何及时准确识别破损舱室的位置,并在最短时间内迅速确定舰船的浮态和稳性,采取正确有效的抗沉措施的研究,对于恢复舰船生命力和战斗力具有重大而又现实的意义[2]。本文基于三维软件SolidWorks为研究平台,使用高级语言VB编写程序对其进行二次开发,同时进行可视化界面设计,应用Microsoft文件存储,实现了基于三维模型的浮态调整计算和在SolidWorks环境下实时仿真,可视化、自动化程度高,并开发出了相应的浮态调整实时仿真计算软件[3]。本文主要介绍了舰船完整浮态的计算和调整、破损浸水过程中舰船浮态改变的计算和仿真演示、如何快速调整舱室进行舰船浮态的扶正计算和仿真演示等主要功能。其中完整浮态调整是利用油舱之间燃油的输送进行微调,以达到规定要求的浮态；然而破舱进水后可能会导致舰船倾斜浮态很大,这时扶正措施可以采用对舱室进行灌排水来调整浮态。本文介绍了基于三维模型的船舶浮态调整实时仿真计算方法的关键技术,在Visual Basic中设计系统的主界面,利用二次开发技术进行实时仿真计算。通过算例验证,本方法可以自动化、参数化、可视化、快速地实现相关命令,系统界面简洁实用,人机交互性好,使用者可以通过简单的程序操作来快速完成舰船浮态调整计算问题,减少计算时间,仿真效果直观、具体、逼真,还有重要的一点是能够实时仿真,时效性非常高,具有很强的实用性。
[Abstract]:The research on the survivability of ships is one of the core contents of modern naval ship design. Survivability is the ability of ships and their systems to maintain or restore their navigation, combat and other technologies to the maximum extent when they encounter accidents in the natural environment, average or damage in the combat environment [1]. Especially in modern naval warfare, once the ship is damaged into the water, if it can not effectively resist sinking, it will directly threaten its combat effectiveness and survival ability. How to identify the position of damaged cabin in time and accurately, determine the floating state and stability of ship quickly in the shortest time, and take correct and effective anti-sinking measures are of great and practical significance for restoring the vitality and combat effectiveness of ship [2]. In this paper, based on the three-dimensional software SolidWorks as the research platform, the high-level language VB is used to write the program to carry on the secondary development, at the same time carries on the visual interface design, applies the Microsoft file storage, realizes the floating state adjustment calculation based on the 3D model and the real-time simulation in the SolidWorks environment, the visualization, the automation degree is high, and has developed the corresponding floating state adjustment real-time simulation calculation software [3]. This paper mainly introduces the calculation and adjustment of the complete floating state of the ship, the calculation and simulation demonstration of the change of the floating state of the ship in the process of damaged flooding, and how to quickly adjust the cabin for the correction calculation and simulation demonstration of the floating state of the ship. Among them, the complete floating state adjustment is to use the fuel transportation between the oil tanks to fine adjust the required floating state; however, after breaking the tank into the water, the ship tilt floating state may be very large, at this time, the rectification measures can be used to adjust the floating state by irrigation and drainage of the cabin. This paper introduces the key technology of real-time simulation calculation method of ship floating state adjustment based on three-dimensional model. The main interface of the system is designed in Visual Basic, and the real-time simulation calculation is carried out by using secondary development technology. The example shows that this method can automate, parameter, visualize and realize the related commands quickly, the system interface is simple and practical, the human-computer interaction is good, the user can quickly complete the calculation problem of ship floating state adjustment through simple program operation, reduce the calculation time, the simulation effect is intuitionistic, concrete and lifelike, and the important point is that it can be simulated in real time, the timeliness is very high, and it has strong practicability.
