基于互联网的船型设计与航速预报应用服务系统

在702研究所微机版软件系统SHIDS3.0的基础上,开发了基于互联网的、界面友好的在线式船型设计与航速预报应用服务系统SHIDSweb。重点介绍了该软件的开发过程、技术优势及其应用情况、收费与网络用户管理机制、用户开发及未来发展计划。用户可根据船舶主尺度和主机参数,通过互联网应用该系统快速进行船型设计、静水力计算、阻力及自航因子估算、螺旋桨设计及航速预报,并对该船型进行耐波性和操纵性初步估算。该系统同时提供了船型几何及其快速性能试验结果的数据库查询。

Internet Service System for Hull Form Design and Hydrodynamic Performance Prediction

Based on the PC program SHIDS 3,0 of CSSRC, a new user-friendly internet service system SHIDSweb is developed. This system is mainly used for hull form design and hydrodynamic performance prediction. The computation modules and management modules of this system are introduced, as well as the developing premeds, technical advantage and application cases. User developing and future plan are also discussed. Running this system via a terninal linked to internet, a user can quickly generate a hull form, design the propeller and predict the speed of the ship according to principal dimensions and main engine condition, then also can evaluate its maneuverability and sea-keeping perforraance. A database with form offsets and data of model test is also provided for user referring.
