摘要
采用两种加载方式对某浮吊锚机基座及相关船体结构的局部强度进行直接计算,并对比分析两种方法所得的应力结果,结果表明,两种方法是应力结果差别较大,在应力水平较低时两种方法都可以用来计算校核基座及其支撑结构的局部强度;当应力水平接近许用应力时,建议采用MPC加载方式计算评估。
In the direct strength assessment of the windlass＇ s foundation and its supporting structures,two methods to apply the loadings are adopted,and the stress results are compared and analyzed. It can be concluded that both of the methods can be used to assess the local strength of the windlass＇ s foundation and its supporting structures when the stress level is low,when the stress is close to the allowable stress,the method using MPC is recommended.
