Abstract: In an industrial sinter chain, the drive type of the spider and pallet cars is gear and pin rack transmission. To deal with the defects of arching and velocity fluctuation of pallet cars during run process, the mechanical relation of spider and pallet cars is analyzed. According to the analysis results, the system mechanical model that the pallet cars are non-arching is given and the force control method of new type sinter chain with non-arching and stable transmission is put forward. Applying this model and method and combining with industry example, analytical calculation and motion simulation based on the virtual prototype are carried out. The calculation and simulation results are the same on the whole, so the force control threshold value and the force control curve of sinter chain are obtained. The new type sinter chain designed with the force control method has been put into service. The application effect indicates that the theory of this mechanical model is correct, the calculation and the simulation are reliable and the force control method is effective. The research results can provide the theoretical basis for the engineering design and application of sinter chain in future.
