Abstract

In the railway vehicle assembly problem, it is asked to choose the optimal combination of the railway vehicle wheels with the multiple constraints of assembly requirements, according to the multi-parameter characteristics of railway vehicle wheels matching, the mathematical model of this problem was built, and the solving method based on genetic algorithm was developed, and the corresponding coding method, crossover operation and mutation operation and so on were designed. The method for matching railway vehicle wheels is established, the efficiency and accuracy of the wheels matching was improved by above method, then the running safety of railway vehicle was improved. Finally the effectiveness of the method was verified by an example.
