摘　　要：为准确测定合金凝固时应力产生的瞬间动态变化,以应力框为设计依据制造出测试铸造合金凝固时产生应力的铸造合金应力仪。其核心是通过安装在测杆上的拉压力传感器测试受力变化以及利用热电偶测量合金的冷却曲线,通过数据采集和软件分析处理,精确获得合金不同阶段的应力和温度变化状态。该应力仪可用于铸造工艺及凝固技术的实验教学、科研及生产领域。In order to measure the instantaneous dynamic changes of stress during solidification of alloys accurately, a casting alloy stress detector device is designed to test the stress of casting alloy during solidification by taking the stress frame as the design basis. The kernel is testing the stress change by tension-compression sensor which is installed on the test rod and measuring the cooling curves of alloys by thermocouple, the stress and temperature variations at different stages of the alloy can be accurately obtained by data acquisition and software analysis. It can be used in the experimental teaching, scientific research and production field of casting process and solidification technology.
