Hydraulic Banjo fittings shown in the type of stress values ​​under

Various alloys made of corrugated hose lapse time value (fatigue strength), customary for corrugated hose with the letter N flag, or using these values ​​of the logarithmic means. The vertical axis represents the distribution of credit values ​​of the function F (the left side of the non-aliquot of the scale), the the aliquots scale on the right is obtained by the integral function F after a certain transformation. In Figure 81, Figure 82 and Figure 84, U is the standard normal law or lognormal law of sub-sites. Tabulated normality regular standard integral function [49} SO)sae hydraulic fittings
The figure shows that the experimental distribution law and two forms right the lognormal law and BeR6y of law is consistent ['). In areas of high stress, the experimental data with the normal rules are also good. Exponentially with the experimental function is completely out of line. Judging from the distribution of the fatigue strength of the corrugated hose, which is characterized by extending rightward directions (or a frequency distribution diagram). The density density than at the start of the fatigue strength values ​​of the variation range at the terminal, that is, the fatigue strength of the corrugated hose A distribution law with respect to the mathematical expectation itself is asymmetric.valve block
