In order to investigate the influences of the optical forces on the lattice structure of an electrorheological (ER) suspension, on the basis of the experiment of Michael M. Burns etal., comparing their sample with an Electrorheological suspension, this paper substantially discusses the influences of intense light beams on the interaction between the dielectric particles immersed in electrorheological suspensions (ER). It respectively calculates out the optical forces exerted either on the polystyrene spheres in the sample of Michael M. Burns etal. Or on the corn-starch spheres in an ER suspension, the calculation results of this paper show that increasing the intensities of the incident laser beams or the gradient of the applied electric field can generate stronger optical forces acting on the spherical dielectric particles in an ER fluid than acting on those spheres with nearly the same mass and figuration in the suspension sample of Michael M. Burns etal.. Similar to the experimental result of Michael M. Burns et al., when increasing the intensities of the incident laser beams or the gradient of the electric field up to a critical value, it will give rise to the optical crystallization and optical binding of ER suspensions.
