摘要：
Based on finite element method, a program computing wind turbine blade natural frequency was developed. Compared with the experimental results, the program was verified with the example of some 1.5 MW blades. To improve the blade natural frequency, the mass distribution of the girder was optimized and the particle swarm optimization algorithm (PSO) was used. With the same example, the results showed that optimized first order flap-wise frequency was enhanced about 3%.
