Research on characteristics of colloidal aggregates with Lennard-Jones potential under shear has been carried out. The features included cluster size distribution, radial distribution function, fractal dimension and coordination numbers. It revealed that cluster size distribution approached to smaller size, radial distribution function and coordination number reduced graduately with increasing shear rates. When shear rates increased, fractal dimension ranging 1.9-2.4 increased first then decreased slightly. Shear did not change fractal dimension obviously, however (clusters were stretched at X (shear rate) direction and deviated from the X direction at high shear rates.
