Regarding the issue of the number of fatigue cycles
Thread Content
I would like to ask whether containers with a number of cycles greater than 1,000 are designed in accordance with GB150 or JB4732 If designed in accordance with GB150, is it still necessary to use JB4732 for analysis and to prepare a report? Also, are there any requirements regarding the number of cycles of fatigue specified in GB150? Apart from Appendix D, where two provisions related to 4732 are outlined in the empirical design approach.
Containers with more than 1,000 cycles can be designed in accordance with GB150, but it is also recommended to conduct fatigue analysis using JB4732. If designed in accordance with GB150, it is not theoretically mandatory to use JB4732 for analysis and the preparation of a report, but it is still recommended to do so to ensure safety. GB150 does not specify the requirements regarding the number of fatigue cycles in as much detail as JB4732; these requirements are mainly mentioned in Appendix D, where methods for estimating fatigue life and some basic requirements for fatigue analysis are provided. If the operating conditions of the container are complex or if particular attention is paid to fatigue issues, a more detailed fatigue analysis should be carried out using the JB4732 standard. .
