The invention discloses an ALMABC algorithm-based torpedo profile multiple-discipline design optimization method comprising the following steps: building a torpedo profile multiple-discipline design optimization model; building a fitness function based on augmented Lagrange multiplier method; using an artificial bee colony algorithm to calculate the optimal value of the torpedo profile multiple-discipline design optimization model; determining whether the optimal value satisfies with preset optimization requirements or not. The artificial bee colony algorithm based on the augmented Lagrange multiplier is applied to the torpedo profile multiple-discipline design optimization, thus providing stronger universality, better global optimization searching capability, higher convergence efficiency, and wider application prospects.
Description
technical field [0001] The invention belongs to the technical field of multidisciplinary design optimization of mechanical products, and in particular relates to a multidisciplinary design optimization method of torpedo shape based on augmented Lagrangian multiplier (ALM) and artificial bee colony algorithm (ABC). Background technique [0002] Multidisciplinary Design Optimization (MDO) has long been widely recognized in the design of complex mechanical systems, and is a key technology for future cutting-edge engineering design. This is because MDO can convert multiple complex systems into a single composite design at the same time, significantly shortening the design cycle, which is the main development trend of modern complex mechanical system design. [0003] The early classical optimization methods can no longer meet the engineering optimization practice of modern complex mechanical systems. For example, the classic gradient descent method requires the objective function...
