摘　　要：利用VC++6.0的动态链接库技术,设计一种基于NI-DAQ的双轴拉伸试验平台。采取行程等分定点触发方式,实现超弹性膜材料双向拉伸试验的数据采集,介绍利用NI运动控制卡及数据采集卡进行运动控制和数据采集的具体步骤。实践证明,该双轴拉伸平台能较好地满足超弹性膜材料的试验要求。Making use of the VC＋＋6.0 dynamic link library technology,the biaxial tensile test platform based on NI-DAQ was designed.Taking the method of fixed-point trigger in equal displacement,a hyper-elastic membrane tensile test data acquisition was completed.The detailed steps about the motion control and data collection of using NI motion controller and data acquisition cards were related.The practice proves that the biaxial tensile test platform can meet the experimental requirements of hyper-elastic membrane material.
