In a given clock mechanism, the tolerances of its structural parameters often cast profound influences to the accuracy of the timing output. In this paper, the tolerances of the clock mechanism parameters are studied to explore its influence on timing. Through 3D modelling of the proposed clock mechanism along with related multi-rigid-body dynamics simulations, full factorial experimental design method is used to investigate the impacts of structural parameters onto the timing contribution. The results of experimental design illustrate that the center distance between escape wheel and pendulum, and the diameter of escape wheel addendum have a higher influence on the timing of clock mechanism. Based on the probability distributions of the clock mechanism structural parameters, Monte Carlo simulation is applied to obtain the probability distributions of timing. The simulation results suggest that the timing follows the pattern of a normal distribution and most of its values are in the vicinity of the average.
