Bathtub curve analysis in mining equipments pdf

bathtub curve, illustrated in Figure 1, is a statistical depiction of the failure rate over the lifetime of a population of products; and it is related to a failure-distribution curve (see . Figure 2). They can be combined to form a continuous curve [1]-[4]. 2 Prognostics

    As we know the bathtub curve is widely used in reliability engineering which shows the trend of failure rates of a system or equipment obtained throughout its life period. The trend looks like the cross-sectional shape of a bathtub so it is termed as bath tub curve. An ideal bathtub curve is shown in the figure-1.It mainly comprises of three parts:

Bad news is that some vendors, even major
