The methodology used to measure transient temperature changes in impacted solids, using high-speed infrared detectors, is presented and discussed thoroughly. The various steps leading to a reliable measurement, namely selection of the sensing device, calibration of the setup, interfacing with the impact apparatus (Kolsky bar), and data reduction are presented. The outcome of the above methodology is illustrated in terms of the Taylor-Quinney factor, a well-known measure of the efficiency of the thermomechanical conversion.•Selection of infrared detectors.•Importance of the calibration procedure.•Determination of the Taylor-Quinney factor.
本文详细介绍并讨论了使用高速红外探测器测量冲击固体中瞬态温度变化的方法。文中介绍了实现可靠测量的各个步骤,即传感设备的选择、装置的校准、与冲击装置(科尔斯基杆)的连接以及数据处理。上述方法的结果通过泰勒 - 奎尼因子进行说明,泰勒 - 奎尼因子是热机械转换效率的一个著名度量。
