| Abstract: | Based on the interference theory of stressstrength, the strength of joint board of the cottonseed shell huller and separator worsened gradually because of long-time dynamic load, the distribution median of strength tended to retrogress. The strength retrogression of the joint board was discussed, an estimation formula was used to calculate the strength retrogression of an example. |

| Keywords: | cottonseed shell huller and separator joint board reliability fatigue limits strength retrogression |
