本文介绍了对球罐错边和角变形引起的附加应力的测定结果。建立了力学模型并介绍了附加应力计算式。另外,还介绍了适于计算式要求的角变形量的测量方法,以及用此法则得的数值与用部颁标准规定的测定方法测得的数值的互换关系。最后对附加应力进行了理论分析和误差分析。前言大型压力容器在装配焊接过程中,不可避
In this paper, the results of measuring the additional stress caused by the wrong side and corner deformation of the spherical tank are introduced. The mechanical model is established and the formula of additional stress is introduced. In addition, the method of measuring the amount of angular deformation suitable for the calculation formula is also introduced, and the relationship between the numerical value obtained by this method and the value measured by the measurement method stipulated by the Ministry of Standards and Regulations is also introduced. Finally, the theoretical analysis and error analysis of additional stress are carried out. Preface Large pressure vessel in the assembly welding process, inevitable
