摘要： 为了研究食物块在口腔中的咀嚼破碎过程,利用离散元的方法提出了咀嚼破碎模型。以大豆为例,测试了大豆与大豆之间、大豆与牙齿之间的相应参数,模拟了大豆在口腔中的咀嚼过程。为了验证模型的可行性,利用逆向工程技术建立了人类第一上、下磨牙的三维模型,研制了齿形压头,配合质构仪对大豆进行破碎,分析了受力变化,与仿真得到的受力变化趋势一致,仿真值经过一元线性回归模型的修正得到试验值,模型的判定系数达到了0.956,表明咀嚼破碎模型可以模拟人的咀嚼运动,为评价食品的质地提供了一种新方法。

Abstract: In order to study the breaking and chewing process of food in mouth, a chewing broken model was using discrete element method. Taking soybean as an example, the dynamic chewing process was simulated and the corresponding parameters were tested, including that between soybean and soybean, and between soybean and teeth. To verify the feasibility of the chewing model, three-dimensional models of the first upper and lower molars were established using reverse engineering. The dentiform indenter that works with the texture analyzer was developed. Test of the soybean crushing with the dentiform indenter was carried out and the forces in the crushing process were analyzed. The changes of forces in the test are in line with that in the simulation. The simulation values could be amended by the linear regression model, and the regression coefficient approached 0.956. The analyzed results show that the chewing broken model can be used to simulate the chewing process of human, providing a new method for food texture evaluation.

Key words: computer application, discrete element method, chewing broken model, chewing, reverse engineering
