Abstract:

This paper presents the reliability design method of driveaxle housing for forestry mechanary. On the condition that the probability distribution of the basic random variables is given, an effective and practical method for this design is put forward with the technique from perturbation method and reliability design theory. The theoretical formulae of the reliability design are induced. The correspondin computer program is made and can be used to accurately and quickly obtain the parameters of the reliability design of driveaxle housing.

Key words: Drive-axle housing, Reliability design, Perturbation method
