摘　　要：复合阻尼钢板有效地把金属材料和高分子材料的特性结合起来使用,使其既具有金属材料原有的力学性能及加工成形特性,又具有高分子材料的阻尼特性,是振动、噪声场合替代金属材料使用的理想环保产品。但其焊接难点制约了其应用的推广。本文通过对复合阻尼钢板进行激光深熔焊接,获得了合适的焊接工艺参数,采用有限元软件ANSYS模拟了在此参数下阻尼钢板的温度场分布。结果表明:焊接熔池的模拟结果与试验结果基本吻合。Composite damping steel plate was used effectively by combining the characteristics of the metal materials and polymer materials, which makes it have the metal material properties of mechanical and process forming, but also the damping properties of polymer materials. Composite damping steel plate is an ideal environmental protection product which can replace the metal materials in the vibratory and noisy circumstance. But the welding difficulty restricts its application. This article obtain suitable welding process parameters by deep penetration laser welding to the composite damping steel plate, the temperature field distribution was simulated under obtained parameters by using finite element software ANSYS. The results show that the welding molten pool of the simulation results almost agrees with the test results.
