	<span lang=\"EN-US\">In hot-dip galvanizing lines, undesirable vibration of
the moving steel strip occurs due to the impingement of the high-speed
turbulence jet, which leads to non-uniformity of zinc thickness, as well as
splash of the liquid zinc. In this paper, the turbulent jet flow field is
firstly numerically obtained using the CFD method. Then, the influence of the tur</span><span lang=\"EN-US\">bulent jet
flow on the steel strip is simplified as a harmonic force at the impingement line, and the response of the steel strip is obtained by means
of finite element analysis for different strip lengths, thickness and
pretension forces. Influ</span><span lang=\"EN-US\">ences of impingement distance, air knife slot
gap and jet pressure, on vibration of the steel strip are also analyzed. The
results will provide theoretical basis for the reduction of steel strip
vibration in continuous hot-dip galvanizing process.</span>
