Patent ID: 7949478

Claim:
A hose assembly analysis apparatus for estimating an in-situ lifespan of a hydraulic or pneumatic hose assembly in an installation, the hose assembly analysis apparatus comprising: a display that displays a plurality of lifespan factors that are to be rated for the installation; and a processor that: receives hose assembly data, receives ratings data input by a user for each of the plurality of lifespan factors that are to be rated for the installation, wherein the ratings data that is received includes, for each of the plurality of lifespan factors, a value representative of a user observed condition for that lifespan factor, calculates an estimated hose assembly lifespan based on the received hose assembly data and the received ratings data, indicates the estimated hose assembly lifespan, and determines an impulse lifespan as a step in calculating the estimated hose assembly lifespan, the impulse lifespan being based upon wear caused by pressure pulses in a conveyed hydraulic or pneumatic fluid.
