| Abstract: | Calculative model of realistic compression ratio of oil plant was developed on the basis of hyperbolic stress-strain model. Numerical simulations of realistic compression ratio of rapeseed, rapeseed kernel, peanut, soybean, sesame and linseed were carried out. The simulated results coincided with those gained from experiments. The realistic compression ratio of rapeseed kernel was 20% greater than rapeseed. By using variation rate and slope curves of realistic compression ratio, 80 MPa is defined as the critical pressing pressure of rapeseed, rapeseed kernel, peanut and linseed, 100 MPa is defined as the critical pressing pressure of sesame, and 60MPa is defined as the critical pressing pressure of soybean. |
