摘　　要：为了研究锤片形状、间距对PVA分散机性能的影响,运用流体力学软件fluent对相邻交错锤片间流场进行模拟,并通过对间距为20 mm、30 mm的犁型、直叶型锤片中间剖面压力分析,得出间距为20 mm犁型锤片分散效果最佳,并以18 mm长的PVA纤维为对象,通过实际试验予以验证。In order to study the effect of hammer's shape, spacing to PVA dispersion machine's performance, adjacent stag-gered flow field between the hammer is simulated by using fluid dynamics software FLUENT, and by analyzing the spacing 20mm and 30mm plough type, direct leaf type hammer in the middle section of the pressure ,the simulation results is got that distance 20mm plough type hammer dispersion's performance is best, and passed the actual test.
