摘要
塑料大棚越来越多地应用于蔬菜生产。为验证大棚骨架的强度,用农机测试中的应变测量法,来探索其内部应力的变化情况。现这样所得到的结果与理论分析和计算吻合,骨架强度可满足杭州地区要求。
Plastics greenhouses have been made more and more applications to the vegetable production. The strain test in the agricultural machinery field was used to probe the stress variation inside a frame in order to examine the strength of the plastics greenhouse frames. The test showed that the results tallied with the theoretical analysis and caculation, and the strength of frames met the requirement of Hangzhou region.
