摘要:
在基于应变的管道设计方法中,临界屈曲应变是一个重要指标。对现有文献和标准中临界屈曲应变预测公式的不足做了分析说明。根据现有的临界屈曲应变试验数据,对影响临界屈曲应变的主要因素进行了分析,采用灰色关联度法对4个影响因素进行了定量计算和排序,提出了对现有临界屈曲应变预测公式的改进建议。
Abstract:
The critical buckling strain is an important data in the strain-based design of pipelines.This article analysis the shortage of exiting critical buckling strain equations and the influencing factor on the critical buckling strain.According to the grey system theory, the factors affecting the critical buckling strain were analyzed and the correlation between the factors and the critical buckling strain was quantitatively measured based on test data.Then some advice were provided for the improvement of critical buckling strain equations.
