设计了一种新型包装材料蠕变试验测试系统，采用声卡作为数据采集设备，厚度变化量即位移，通过位移传感器输入给V/F转换器，可得到一系列的频率值。声卡将这些频率值采集到计算机中，通过LabVIEW编程，就可得到材料的应变-时间曲线。这种新的测试系统可使得包装材料蠕变特性的测试更加智能化和信息化。

A new packaging material creep test system was designed, which used sound card as data acquisition equipment. The thickness variation can be transferred to the V/F converter by the displacement sensor to produce a series of frequency value. All these frequency are delivered to computer by the sound card. ε-t curves can be obtained using LabVIEW software programming. The newly developed test system makes creep test more intelligent and information-based.
