摘    要:通过研究野生富硒植物薇菜的粘弹性力学性质等为食品物性学研究提供生物力学参数。选用吉林省汪清县山区野生薇菜为研究对象,对野生薇菜茎进行拉伸、压缩、弯曲、冲击、应力松驰、蠕变试验。得出了薇菜拉伸最大载荷、应力、应变、弹性模量、弯曲弯矩、弯曲应力,得出了薇菜冲击功、冲击韧性;还得出了薇菜茎应力松驰、蠕变试验数据和曲线,用三参数模型对应力松驰,蠕变数据进行拟合,得出了应力松驰方程,蠕变方程,得出了薇菜应力、应变随时间的变化规律。薇菜具有良好的生物力学性能,属于粘弹性材料。

关 键 词:薇菜    生物力学    拉伸    压缩    弯曲    冲击    粘弹性

Abstract:In order to provide the biomechanical parameters, research on the osmunda cinnamomea which is a kind of plant full of Se was conducted. Sampling the wild osmunda cinnamomea at Wangqing county mountainous area of Jilin Province, the pull, compression, impact, stress relaxation and creep tests on the samples were done respectively. The maximum pulling load, stress, strain, modulus of elastics, bending moment, stress, impacting work, tenacity, the stress relaxation and creep data and curves were obtained. With tri-parameter model fitting the experimental data of the stress relaxation and creep formulas were obtained. Osmunda cinnamomea is of good biomechanical properties and is a kind of viscoelastic material.
Keywords:osmunda cinnamomea  biomechanics  pull  compression  bend  impact  viscoelastic properties
