According to fluid dynamics numerical algorithm, Reynolds averaged N-S equation and RNG k-εturbulent model are used for wind tunnel simulation of oil loading arm to acquire its wind pressure distribution and wind load,and the influence of the wind direction change on the wind load is discussed. The rational improvement design scheme is proposed on the basis of this fact.
