The Influence of Chosen Abrasive Wear Parameters on Fault-free Operation Time of the Cylinder-Piston System

In the paper the method of data modeling for damages, that has values higher than zero, is being shown. With the use of Weibull distribution, with prior regression and correlation analysis, the chosen parameters, that define durability and break down level of two populations of AlSi17Cu5Mg, were set. The calculation sheet that is shown for reliability allows the creation of so called survival chart, and on the basis of durability data the average warrantee time can be defined at the pre-exploitation stage.
