夹层隔热板相对挠度的一种新测试系统及对有关部标的商榷

A NEW MEASURING SYSTEM OF RELATIVE DEFLECTION OF HEAT INSULATION SANDWICH PLATE AND DISCUSSION CONCERNING MINISTRY STANDARDS

文章介绍了以水重作为均布载荷的夹层隔热板相对挠度的一种新测试系统以及精度的确定。并对有关部颁标准ZBX99003－86和JB／T6527－92作了探讨提出了修改意见。

This paper introduced a new measurlng system, using water as a king of even distributed load, for measuring of relative deflection of heat insulation sandwich plate which widely used in cold stores. The results show that the accuracy of measurements by means of the system sufficiently approaches to 10-4. Approsal has been raised for modifica-tion 0f the Standard of ZBX99003- 86 and JB/T6527- 92.
