Introduction Because of the role of design loads and a variety of external factors in its service environment, Engineering structures, such as high-rise buildings, large bridges, and grid structure etc, will inevitably produce damage accumulation or resistance declining to affect the service life of structure and even lead to unexpected accidents .Therefore, structural health monitoring and damage detection have important significance to avoid catastrophic accidents.

Summary Through the numerical simulation, the author found that pitch of the propeller and blade radius have a large effect on the particle motion, took the larger radius of blade, can promote the flow of particles, but will affect the settlement of small particles at the same time, and cause unevenly mixed; Pitch value is too small, particles are prone to sideslip, it is unfavorable to particle movement, so in the design of blade, engineers should choose reasonable blade radius and pitch according to the size of the mixer bulk, References [1]Cundall P．A．
