【Abstract】 Based on thermal interference analysis,an automatic pipe-routing algorithm was proposed.The algorithm consists of pre-processing phase and searching optimization phase.By chaos theory and thermal analysis principle,the pre-processing phase was aimed at establishing the pre-processing model based on thermal interference analysis.By pre-processing model,the pipe-routing space reduced efficiently the complexity of pipe-routing algorithm and met thermal safety requirements.In the searching optimization phase,a modified ant colony algorithm was designed to provide an efficient automatic pipe-routing algorithm.By contrastive experiment,it shows that the modified ant colony algorithm effectively increases diversity of swarm and has well performance.Finally,the examples illustrate effectiveness and practicability of the automatic pipe-routing algorithm.更多还原
