    • A computer system enables a noise level associated with a structural substrate to be reduced. The computer system includes a memory device for storing data, and a processor in communication with the memory device. The processor is programmed to define a modulus of elasticity, a thickness, and/or a distribution associated with one or more damping elements coupleable to the structural substrate, define at least one operating parameter associated with the structural substrate and the one or more damping elements, simulate a first performance of the structural substrate and/or the one or more damping elements to generate a first performance data set; and determine whether the first performance data set satisfies a predetermined threshold. The first performance data set is associated with the at least one operating parameter and the modulus of elasticity, the thickness, and/or the distribution associated with the one or more damping elements.
    • 计算机系统能够降低与结构基底相关联的噪声水平。 计算机系统包括用于存储数据的存储装置,以及与存储装置通信的处理器。 处理器被编程为定义与一个或多个可耦合到结构基底的阻尼元件相关联的弹性模量,厚度和/或分布,限定与结构基底和一个或多个阻尼元件相关联的至少一个操作参数 模拟结构基板和/或一个或多个阻尼元件的第一性能以产生第一性能数据集; 并且确定第一性能数据集是否满足预定阈值。 第一性能数据集与至少一个操作参数和与一个或多个阻尼元件相关联的弹性模量,厚度和/或分布相关联。
