摘要
根据机械强度可靠性设计的应力强度分布干涉理论,棉籽壳破碎分离机连接板零件在长期动载荷的作用下,强度逐渐恶化,强度分布中值呈衰减趋势.就该机械零件的疲劳强度衰减问题作了讨论,并在估算公式的基础上,进行了实例计算.
Based on the interference theory of stress-strength, 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.
