随着国内化工和电力行业的发展,对管道管件及支架的局部应力分析提出了更高的要求,同时限于客观条件的限制,经常有非标支架设置在管件上,这种情况在现有规范并没有合适的定义,本文针对三通下方设置了假腿支架的案例,介绍了一些理论推导过程,并结合ANSYS软件,列出了计算步骤和其中的注意事项,并引入了压力容器规范里的评判标准对应力进行评定。
With the development of domestic chemical industry and power industry, the local stress analysis of pipe fittings and brackets has been put forward higher requirements, but also limited to the objective conditions, often non-standard bracket set in the pipe fittings, this situation in the existing specifications There is no proper definition. In this paper, a case of prosthetic leg support is set up under the tee, some theoretical derivation processes are introduced, and the calculation steps and precautions are listed in combination with ANSYS software, and the pressure vessel specification is introduced Criteria for the assessment of stress.
