研制了一种挺度测试仪测量纸餐盘整体挺度值,用于表征纸餐盘的承载能力。测量时模拟人一端手持纸餐盘,而另一端加压至与水平面呈15°角时,记录纸餐盘所承受的力。整体挺度值相比负重性能值能更精确地区分纸餐盘之间的差别。
A kind of stiffness tester was developed to measure the overall stiffness of paper tray, which is used to characterize the carrying capacity of paper tray. The measurement simulates the hand-held paper tray at one end and the other end pressurizes to the force that the paper tray withstands when angled at 15 ° from the horizontal. The overall stiffness value can distinguish the difference between paper plates more accurately than the load performance value.
