250t肋骨冷弯机设计及机架结构强度计算

Design of 250 t Frame Cold Bender and Calculation of Structural Strength of Fuselage

介绍了 2 5 0 t肋骨冷弯机技术性能以及结构特点 ,2 5 0 t肋骨冷弯机能满足船厂造船能力为 3万 t船舶的需要 ,并在传统肋骨冷弯机基础上对其结构做了大量的改进和完善 .改进后的肋骨冷弯机机构更简单、性能更可靠、操作维修更方便 .对设计后的机架结构强度进行了校核 ,中机架、侧机架满足结构强度要求 .

This paper introduces technical function and structural characteristics of 250t frame cold bender.Bender can meet shipyard’s demand of building a 30000t ship.Many mechanisms are improved and perfected on the basis of traditional frame cold bender.The mechanisms of the improved bender are simpler and its function is more reliable.The operation and maintenance are more convenient.Strength of fuselage is rectified.
