Abstract: The probabilistic perturbation method and the Edgeworth series technique are employed to devise a practical and effective method for the reliability optimization design for coil-tube springs with non-normal distribution parameters on condition that the first four moments of basic random variables are known. The respective program can be used to obtain the reliability optimization design information of coil-tube springs with non-normal distribution parameters accurately and quickly.

Key words: coil-tube spring, reliability optimization design, probabilistic perturbation method, incomplete probability information
