Design and Simulation of High Temperature Zone Temperature Testing Machine for Quartz Crystal Oscillator

摘要: 本文针对市面上石英晶体振荡器温度试验机在使用过程中无法自动化上下料和检测元器件参数速度较慢的问题进行升级改造，研发一种流水线式多温区温度试验机。本研究通过Solidworks软件建立设备三维模型，利用有限元分析软件comsol对设备工作时的流场进行稳态分析，对设备整体的温度场进行瞬态分析。流场仿真结果显示：设备内部空气流场为湍流，加热效率相较于层流更高；温度场仿真结果显示模具在0℃~25℃、25℃~50℃、50℃~80℃升温状况下，模具升温速度较常规温度测试机有着较大的优势，且被加热模具温度均匀，设备的流水线组合模式提高了生产效率，具有良好的应用前景。

Abstract: In order to solve the problem that the quartz crystal oscillator temperature experiment machine on the market cannot automatically load and load and detect the parameters of components in the process of use, this paper upgrades and develops a pipelined multi-temperature zone temperature experiment machine. In this study, Solidworks software was used to establish the 3D model of the equipment, and the finite element analysis software comsol was used to carry out the steady-state analysis of the flow field of the equipment when it was working, and the transient analysis of the overall temperature field of the equipment. The flow field simulation results show that the air flow field inside the equipment is turbulent, and the heating efficiency is higher than that of laminar flow. The temperature field simulation results show that the heating speed of the mold has a great advantage compared with the conventional temperature tester under the heating conditions of 0˚C~25˚C, 25˚C~50˚C and 50˚C~80˚C, and the temperature of the heated mold is uniform. The pipe-line combination mode of the equipment increases the production efficiency and has a good appli-cation prospect.
