摘　　要：面内压缩性能是表征材料的重要方面。而对于面内压缩来说,为了保证试验的有效性和准确性,需要保证载荷的偏心率在一定范围内。讨论了针对纤维增强塑料面内压缩设计的数字测量系统。为了达到测量和控制精度,应用了特制夹具、专门的AD620仪表放大器和高精度快速数据采集板AMPCI-9101,来保证传力的准确性和测量的准确性,并且编写特殊的软件。依据操作流程进行试验,使得偏心率小于0.1,达到了良好的效果。In-plane compression is an important aspect of material characterization. However, eccentricity must be controlled within a certain range in order to guarantee the validity and accuracy. In this article, the digital measuring system for in-plane compression testing of the fiber-reinforced plastic was discussed. Special fixture, AD620 instru- mentation amplifiers and high accuracy and fast data acquisition board AMPCI-9101 in the system were used and a special software application was made. Experiments under the instruction where the eccentricity is below 0.1 were made, which is an achieved good result.
