A practical calculation method of series-wound system reliability design

Characteristics of series-wound system reliability are explained, accurate algebraic equations calculating the reliability are presented through using mid relevance expressing component relations, a simplified method calculating relative error is derived to check the calculation results for accuracy, the graph of series-wound system with different quantity of components and different weakest component reliability is given. Through a calculation example, it proves that the method is simple, high accurate and appropriate to the practical projects.
