Abstract
Based on the good conductive properties of pressure control granular materials, this paper selects a typical pressure control material titanium diboride (TiB2) as the research object, through the effect of the change of the pressure control resistance value of the particles. Firstly, the force chain structure of particles at different heights was studied by simulation. Then, a method of constructing force-chain-resistance network is proposed, and the rationality of the model is verified by experiments. Finally, the development law of resistance changes with pressure is deeply analyzed, and the structure of force-chain-resistance network effectively combines macroscopic materials and microscopic particles organically, which provides a certain theoretical basis for the resistance response of granular materials with pressure, and provides a reliable basis for its application in the field of electric power.
