Theory analysis of biomass molding mould
The biomass molding is influenced by many factors such as moisture,temperature,Poisson ratio,particle size,length-radius ratio etc.This paper armed to learn the influence of pressures on the biomass molding with different diameter and mainly researched the forces the biomass undergone,including the relationships of molding pressure and the length-radius ratio and that molding pressure and the density.First the material molding process was analyzed and the infinitesimal isobaric model that is pressure vessel model was established.Then this paper analyzed the model and derived these specific mathematics relationships.According to the formulas,this paper used Matlab to program,handled the datum and got the relationship images of the molding pressure and the length-radius ratio and that the molding pressure and the density.Thus it was learned that in plastic deformation area,the pressure and mould radius have the linear relationship while in the shaping area,they have the hyperbolic relationship and the pressure and the length-radius ratio have the linear relationship; Molding density changes with pressure and radius in index.
