Abstract:

Synchronization reliability problems are common in the mechanical field; motion asynchrony will affect the performance or even lead to failure. As action time of mechanisms does not share the identical distribution, the existing synchronization reliability evaluation method has great limitations. Aimed at the problem, a novel synchronization reliability evaluation method is proposed. Starting from two mechanisms, the synchronization reliability of mechanisms can be obtained with recursive algorithm, where synchronization reliability of the mechanisms is expressed as a multiple integral, through dividing the integral domain into several independent domains, the uncertain integral limits are translated into certain integral limits, and then multiple integral can be solved. The numerical examples show that errors between the proposed methods and the MC simulation are very small, which proved that the methods are correct. Finally, synchronization reliability of folding wings is evaluated. The proposed methods make up for the limitations of the existing method and have good versatility.
