基于灰色预测理论的干燥集装袋老化力学性能研究

摘要

FIBC type drying is a new grain drying technology recently . As an important device of the technology , the use performance and the safety performance of the Dry FIBC is particularly important .The mechanical properties of FIBC anti-aging were predicted by using grey forecast theory . The calculation results pos‐sessed satisfying precision ,can meet to the need in engineering practice . T he results show ed that the ten‐sile strength of the Dry FIBC descended with the increase of aging time . But the security service life can reach to 2 years , w hich meet to the design requirements of the FIBC type dring .%袋式干燥是近年来出现的一种新型粮食干燥技术。干燥集装袋作为该技术的重要装置，其使用性能与安全性能尤为重要。基于灰色预测理论，对干燥集装袋基材老化力学性能进行预测，预测结果具有良好的精度，可满足工程实际对干燥集装袋老化性能预测精度的要求。试验和预测表明，随着老化时间的增加，干燥集装袋基材的抗拉强度不断下降，但其安全使用寿命均达到2年，满足袋式干燥设计要求。
