Abstract

A gear transmission multidisciplinary reliability analysis method considering cognition and random uncertainty in an actual engineering design process belongs to the technical field of design optimization and reliability design of mechanical products and includes quantizing the cognition and the random uncertainty of gear modules, tooth number, tooth surface width, distance between bearings and gear diameter caused by the factors of processing, assembly, material characteristics, applied load, external environment and the like, establishing multidisciplinary reliability integrated evaluation index, integrating of the reliability analysis method and a multidisciplinary design optimization strategy, decoupling of a multidisciplinary reliability analysis process, and being based on a functional measurement method. The gear transmission multidisciplinary reliability analysis method considering the cognition and the random uncertainty provides a comprehensive quantitative method, establishes the multidisciplinary reliability integrated evaluation index which is more conformable to engineering practice, integrates a traditional reliability analysis method and the multidisciplinary design optimization strategy, and provides a new thought for reliability analysis of gear transmission products.

Description

technical field

[0001] The invention belongs to the technical field of reliability design of complex products, in particular to a multidisciplinary reliability analysis method of gear transmission under the condition of multi-source uncertainty. Background technique

[0002] Gear transmission system is a common form of power transmission in large and complex equipment such as aerospace vehicles, aero engines, ships, large electromechanical equipment, weapons and vehicles. The performance, especially reliability, of gear transmission directly determines the quality of large and complex equipment. Therefore, people have carried out relevant research on the reliability of gear transmission from the aspects of product design, product manufacturing and product maintenance. According to relevant statistics, the contribution rate of product design to product quality can reach 70% to 80%. It can be seen that the design determines the inherent reliability of the product and endows t...
