摘要: 采用MSC.Marc非线性有限元软件,对薄板激光弯曲过程中的温度场进行了数值模拟 ,得到了引起薄板激光弯曲变形的温度场的变化规律.通过温度传感器测量与激光扫描线相 对应的薄板下表面温度变化的规律来验证数值模拟的结果.模拟值与实测值基本吻合,表明 数值模拟结果可作为激光加工工艺参数选择的依据.

Abstract: Temperature field in the laser bending process was numerically simulated by MSC. Marc software. Variations of temperature with time to cause sheet metal bending were calculated. Simulation result was verified by the temperature on the lower surface of the sheet metal, which was measured by the thermocouple temperature t ransducer measuring under the laser scanning line. Experimental curves of temper ature versus time are in agreement with simulation results. The simulation resul ts can be regarded as a basis for choosing laser technological parameters.
