Random packings of spherical particles have attracted attention for many years. An algorithm based on compression is developed to generate random packings of spherical particles in this paper. This method is different from previous compression-based algorithm. In order to increase the packing density, a process of shaking is applied during packing process. The algorithm is mainly composed of three procedures:generating initial packing configuration by using random sequential adsorption ( RSA ) , compressing packing domain, and shaking. The packing structure is characterized by packing density and coordinate number. The packing density increases with iteration number and a stable packing configuration is obtained after the iteration number is more than 34 000. The packing density is 0. 85 and the average coordinate number is 3.7 in a stable packing configuration.
