【摘要】 散装谷物船舶作为世界商船队中重要的组成部分，在国际贸易运输和近洋、沿海及内河运输中起着非常大的作用。 散装谷物在装运时，由于其自身的特性使谷面产生移动，从而影响船舶的稳性，威胁船舶的安全，因此，对散装谷物船舶稳性的研究一直是船舶设计和研究人员及航海人员非常关心的课题。国际海事组织IMO也据此制定出最新散装谷物运输规则，以达到最有效地调整和控制散装谷物船舶的稳性，为海上谷物安全运输起到保障。 根据IMO规则和海运界惯例及其经验，以散装谷物船舶特殊的稳性计算校核方法建立算法。同时考虑专用船舶的稳性计算，并引进IMO关于专用船舶稳性计算的方法和规则，从而实现了谷物倾侧力矩的完整算法。此外，提高GZ曲线处理方法的精度，并将拉格朗日插值、牛顿上山下山法等数值分析方法应用于模型之中；最后通过软件编程完成了散装船舶稳性计算表格的自动实现系统。 该系统界面简洁，具有很好的易用性；精度较高，能有效计算散装谷物船舶的稳性，可以根据不同的船型参数，输出相应的稳性值；可以根据具体船舶的需要修改程序的部分源代码，能够与其他船舶应用软件结合，实现船舶不同应用的整合，具有高扩展性。 该系统具有较强的实用价值，最直接收益的将是船舶上负责稳性计算工作的大副和负责检查散装船舶稳性的各国检查人员，采用该系统将大大降低他们的工作强度，提高工作效率，附有系统提示功能，将有效降低或避免老式稳性表格数据错误、来源不明确等因素带来的影响。更多还原

【Abstract】 As an important component of the world’s merchant fleet, bulk grain carriers is playing the extremely major role in international trade transportation and near ocean, coastal as well as inland waterway transport.In bulk grain shipments, the valley surface is likely to have a migration due to its own characteristic, thus affects the ship’s stability and threatens the safety of ships. Therefore, stability research of bulk grain carriers has been a great concern for ship design stuff and the mariners. IMO also formulated the latest bulk grain transport regulations to effectively adjust and control the stability of bulk grain vessels, and thus to safeguard the grain transportation.According to IMO rules and maritime practices and their experience, establishing a algorithm based on the special stability calculation and checking method , meanwhile concerning about exclusive ship stability calculation, and with the introduction of special IMO Ship stability calculation methods and rules, thus has realized complete algorithm of grain rolling moment. In addition, GZ curve processing method is optimized for better accuracy, and Lagrange interpolation, Newton’s law numerical analysis method has been applied to the model; Finally, a automatically stability calculation system for bulk carriers is completed through software programming.This system interface is simple and user-friendly; It can calculate bulk grain carriers’ stability effectively with high precision results under vary hull parameters. May revise relevant source code according to specific ship needs and integrate with other ship applications for it’s quiet extensive.The system has a strong practical value, and could be beneficial to the inspectors and the first officer who is in charge of stability work. This system will greatly reduce the intensity of their work and improve efficiency. Prompt function is available with更多还原
