Research on quality achieving reliability of bearing based on fuzzy weight

摘要

摘要: 以模糊数学理论为基础，提出了轴承品质影响因素权重确定的方法。对原始的轴承品质实现可靠性模型进行修正，提出了改进的轴承品质实现可靠性模型，并基于最大熵原理对轴承品质实现可靠性的真值及真值区间进行估计。以30306和30204圆锥滚子轴承为对象进行试验研究，发现原始的可靠性模型计算结果相对于试验结果的偏差为20%~35%，改进的可靠性模型计算结果相对与试验结果的偏差为12%~14%，偏差降低了8%~21%，可见改进的可靠性模型比原始的可靠性模型更准确。

Abstract: Based on the theory of fuzzy mathematics, the method to determine the weight of bearing quality influencing factors was put forward. The original model of quality achieving reliability was modified and the improved model of bearing quality achieving reliability was proposed. Then the true value and true value interval of bearing quality achieving reliability were further estimated based on the maximum entropy principle. Taking two kinds of tapered roller bearing, 30306 and 30204, as experimental objects, it was found that the deviation of the original reliability model calculation from the test results was 20%-35%, and the deviation of the improved reliability model calculation from the test results was 12%-14%, which was reduced by 8%-21%. It can be known that the improved reliability model is more accurate than the original reliability model.
