ABSTRACT
A component will not be reliable unless it is designed with required reliability. Reliability-Based
Mechanical Design uses the reliability to link all design parameters of a component together to
form a limit state function for mechanical design. is design methodology uses the reliability
to replace the factor of safety as a measure of the safe status of a component. e goal of this
methodology is to design a mechanical component with required reliability and at the same time,
quantitatively indicates the failure percentage of the component. Reliability-Based Mechanical
Design consists of two separate books: Volume 1: Component under Static Load, and Volume 2:
Component under Cyclic Load and Dimension Design with Required Reliability.
is book is Reliability-Based Mechanical Design, Volume 2: Component under Cyclic Load
and Dimension Design with Required Reliability. It begins with a systematic description of a
cyclic load. en, the books use two probabilistic fatigue theories to establish the limit state
function of a component under cyclic load, and further to present how to calculate the reliability
of a component under a cyclic loading spectrum. Finally, the book presents how to conduct
dimension design of typical components such as bar, pin, shaft, beam under static load, or cyclic
loading spectrum with required reliability. Now, the designed component will be reliable because
it has been designed with the required reliability.
e book presents many examples for each topic and provides a wide selection of exercise
problems at the end of each chapter. is book is written as a textbook for senior mechanical
engineering students after they study the course Design of Machine Elements or a similar course.
is book is also a good reference for design engineers and presents design methods in such
sufficient detail that those methods are readily used in the design.
