摘要
目的 研究温度对约束阻尼层结构的减振降噪的影响 .方法 采用通过改变温度 ,测量不同阻尼层厚度时试样噪声变化情况的试验方法 .结果 获得了试样噪声声压级随温度变化的趋势 .
Aim\ To study the influence of temperature on the effect of vibration noise controls to constrained damping layer structures. Methods\ The experimental method of testing the variation of noise by changing temperature is used. Results\ The tendency to the variation of noise level with temperature changing has been acquired. Conclusion\ The vibration noise controls using constrained damping layer is effective and varies with temperature.
