Description
technical field [0001] The invention belongs to the technical field of multidisciplinary design optimization of mechanical products, in particular to a multidisciplinary reliability design optimization method of a mechanical arm under time-varying uncertain conditions. Background technique [0002] Modern complex mechanical systems are products with complex structures, many functional requirements, and high performance indicators. How to realize product design solutions that meet users' complex functional and performance requirements while ensuring high reliability is an extremely difficult problem. The traditional design of complex mechanical systems is a cyclical design in accordance with function-structure-strength. This serial mode is essentially that designers choose different key disciplines for design at different design stages, and artificially separates the disciplines of structure, strength, vibration and heat that affect the performance of complex mechanical syste...
