Due to normal variations in dimensions inherent in the manufacture of the components of a mechanism, there is a small probability of not meeting the accuracy predicted by a deterministic representation of the mechanism. The probability of failure of a mechanism can be defined as the probability of deviation from its specified function. This paper presents a Monte Carlo simulation approach for the estimation of the reliability (one minus the probability of failure) of mechanisms and illustrates the procedure by considering a four-bar straight line mechanism. The effect of the probability distribution of the random parameters on the overall reliability is also investigated.
