The reliability of the strength of the corrugated hose

Reliability index corrugated hose is irreversible components, one-time acting elements that failure can no longer be repaired.
In the choice of the irreversible component reliability indicators, on the one hand to it before the expiration of the time distribution law to decide, for corrugated hose that is, the number of load cycles to destroy, but we also need to determined by the scale of production and use of such parts of the corrugated hose; addition, the accuracy and authenticity of identification and control must also depends on the reliability indicators. The reliability index scatter valuation accuracy and authenticity by means of established probability and includes indicators of the true value of the confidence interval to determine the width of the confidence interval [hair magic depends mainly on the capacity of the test.hydraulic hose cutting machine
In order to determine the theoretical distribution law (its best form with the experimental distribution pertinence), to be large enough tolerance test (n> 20); probability paper, a graphical representation of the experimental distribution of the integral function method has been push factory '. If the experimental probability paper approximate a straight line, it would prove that the distribution pattern consistent with experimental data and made probability paper. Intercept and inclination of the straight line in the coordinate axes can be approximately determined by the distribution parameters. Figure 81 --- Figure 85 shows two forms of the log-normal law of probability paper (sensitivity limit N and "sensitivity limit"), as well as in regular irrigation rate paper Bea6yn Normal law of probability Paper and exponentially probability paper-made graphics.metric hydraulic fittings
