Abstract: Aiming at the problems of tamping coking equipment during operation, the working device of tamping coking equipment was studied. The related researchs at home and abroad were summarized, the method of using the Duncan-Chang model as the constitutive model of stamping coking briquette was established. The tamping experiment was carried out to obtain the distribution of the force between the briquette and  box. The constitutive model of briquette and tamping dynamic model were verified with the method of comparison between experimental data and simulation data. Dynamic simulation model for the process that large tamping equipment tamped briquette was set up in finite element method. The size optimization of box structure was designed through the analysis of the box structure characteristics. The results indicate that the auther used the Duncan-Chang model to simulate the constitutive model of briqutte, then devolop the dynamic model to simulate the real stamping process accurately. The size-optimized structure of coal box, with less mass and high economic efficiency, can meet the requirements during the real operation.
