摘要: 通过数值模拟对不同厚度、不同芯材密度的金属面夹芯板隔声量进行计算,并与试验值作比较,验证了软件模拟的可行性。利用数值模拟方法分析钢板的厚度,芯材的厚度、密度与隔声量之间的关系,以共振频率为分界点,拟合金属面夹芯板隔声量的计算公式。比较表明,试验值与计算值误差较小,可以为工程实践提供指导。Abstract: The numerical simulation method is used to calculate the sound transmission loss of two different sandwiches with different thicknesses.Comparing with the experimental results,simulation results are proved to be correct.Then it is analysed the relationship among steel thickness,sandwiches thickness,sandwiches density and sound transmission loss.Setting the resonance frequency as the boundary,formula of sandwiches sound transmission loss is fitted.Error between experimental results and calculated results is small.The formula can direct engineering practice.
