Research on the Variety Law of Time-Dependent Reliability Model of Picking Link Rod in Sewing Machine
2015
The reliability of mechanical component is a time-varied process because the parameters such as operation condition, load, strength, are varied with time or the loading numbers. This paper builds the time-dependent reliability model when life is measured by the loading numbers. The variety-law of component’s reliability with the lifetime is derived from the built model and simulation of picking link rod used in sewing machine. It is shown that the time-dependent reliability model is effective and the reliability of component decreases obviously with the time and the increasing load standard deviation.
