| 中文摘要: |
| 目的 对一种由稻壳粉为主要材料制备的生物基育苗秧钵包装容器的力学性能进行测试。方法 通过静态拉伸试验测得其弹性模量及泊松比， 然后通过对秧钵整体的压缩实验， 测得秧钵杯体不同位置处的极限载荷。在此基础上， 利用有限元软件对该秧钵进行模拟计算。结果 通过模拟计算发现， 该秧钵在受压时整体的应力分布可以分为4层， 其中上层杯口处的应力最大， 最容易破坏， 而秧钵中间部分的应力则较小。结论 该模拟结果与实验结果基本吻合。 |
| 英文摘要: |
| To test a bio-based seedling pot packaging container prepared using rice hull flour as the main material for its mechanical property. Elastic modulus and Poisson ratio were gained by static tensile test, and limit loads at different positions of the seedling pot were obtained by compression test. Based upon the parameters obtained above, simulation calculation was performed for the seedling pot using the finite element method (FEM) software. Simulation calculation found that the overall stress distribution could be divided into four layers under compression. The upper layer near the cup mouth had the largest stress, and would be damaged first, while the middle of the pot had the smaller stress. The results of the simulation were basically the same as the test results. |
