Local strength checking of ships for loading of tracked vehicles

  • 摘要:
      目的  为提高载运履带式车辆装备的船舶局部强度校核的准确性,减少因承载过重而导致船舶变形甚至断裂的情况发生,实现军事装备的安全运输,
      方法  对装备航运过程中的受力(包括重力、系固力、惯性力、波溅力、风压力以及摩擦力)进行分析,结合船舶甲板板架结构的特点,考虑船体腐蚀所带来的不利影响,利用工程力学原理,对船舶局部强度校核方法进行修正。
      结果  得出了稳性校核和强度校核修正公式。
      结论  实例验证发现,修正公式计算的精确度大于未修正的校核公式,能有效避免船舶事故的发生,可为民船载运履带式车辆装备提供技术参考。

     

    Abstract:
      Objectives  In order to improve the accuracy of local strength checking of ships for loading tracked vehicles, reduce the occurrence of ship deformation or even fractures caused by heavy loads, and realize the safe transportation of heavy military equipment,
      Methods  the various forces(including gravity, securing force, inertial force, wave force, wind pressure and friction)of a tracked vehicle are analyzed. Combining the characteristic grillage structure of ship decks and considering the adverse effects of corrosion on ship hulls, an improved method for local strength checking is proposed, and correction formulae for stability checking and strength checking obtained using engineering mechanics.
      Results  Through the validation of examples, it is found that the accuracy of the correction formulae is greater than that of the uncorrected formula.
      Conclusions  The application of such correction formulae to the strength checking of ships may effectively prevent accidents, thus providing valuable technical references for the transport of tracked vehicles by merchant ship.
