Optimization design for complex pipelines inside electromechanical products based on flow resistance loss

Optimization design for complex pipelines inside electromechanical products is a very difficult task within complex products such as cars, planes, ships and rockets. Thus, an optimization design for complex pipelines is proposed based on the flow resistance loss in this paper. The basic framework of the design includes three parts like pre-processing, evalution model and optimization search algorithm. Firstly, Monte Carlo pre-processing model is established to effectively reduce the complexity of the optimizaton design. Also, flow resistance loss model of complex pipelines with branches is constructed to evaluate design. Moreover, a novel particle swarm optimization (PSO) algorithm is presented to find an approximate optimal design. Finally, the comparison experiments and examples demonstrate that the optimization design is effective and practical.
