摘　　要：成功研制出多功能焊接热模拟软件,该软件以实测和经典的数学模型为基础,应用Labview8.2和STEP 7进行编程。用该软件绘制焊接热循环曲线,操作界面简单易行。针对多道次焊接热模拟试验设计的道次间隔时间参数,可以保证试验时每一个道次的初始温度与设定值相一致,有效地改善了以往焊接热模拟试验的不足。软件凭借其稳定性、可靠性、快捷方便性,应用于国产MMS系列热力模拟实验机,完善了国产热力模拟实验机的功能,进一步拓宽了其应用领域。The software for welding heat simulating was developed successfully based on some classical mathematic models,measured data and programmed appropriately by LabVIEW8.2 and STEP7.The interface is simple to draw welding heat simulating curve with this software.Setting parameters of interval time for multi-pass welding heat simulating experiments can make the preheat temperature be consistent to the setting value.The software with good stability,reliability and conveniency has been applied to the series of domestic thermo-mechanical simulator,which consummates the simulator's functions.
