标准圆筒试验技术与数据处理方法研究

 对标准圆筒试验技术与数据处理方法进行了深入研究，在狭缝扫描实验中建立了新型、高效的照明技术、底片判读方法以及数据处理方法，得到了精度高、信息丰富的圆筒壁质点上的位移、速度、加速度和比动能结果。同时，通过VISAR技术直接测量了圆筒外表面径向膨胀速度-时间曲线，进而积分得到位移-时间曲线，与狭缝扫描结果相互印证和补充，进一步提高了测试可靠性。

Study on Standard Cylinder Test Technology and Data Processing Method

Standard cylinder test technique and data processing method were studied, and new effective techniques of lighting, negative interpretation and data processing for slit scan experiments were established, and the results of displacement, velocity, acceleration and specific kinetic energy of the cylinder wall particle with high precision and abundant information were obtained. VISAR was used to measure the cylinder expansion velocity and displacement simultaneously. The obtained results are consistent with those from slit scan experiments. The testing reliability was further improved.
