Methods and systems for determining a structural parameter for noise and vibration control

A computer system for reducing a noise level associated with a structural substrate, the computer system comprising:

• one or more memory devices for storing data;
• and
• one or more processors in communication with the one or more memory devices, the one or more processors programmed to:
• define at least one of a modulus of elasticity, a thickness, and 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 at least one of the structural substrate and the one or more damping elements to generate a first performance data set, wherein the first performance data set is associated with the at least one operating parameter and the at least one of the modulus of elasticity, the thickness, and the distribution associated with the one or more damping elements;
• determine whether the first performance data set satisfies a predetermined threshold;
• if it is determined that the first performance data set does satisfy the predetermined threshold, reducing the noise level associated with the structural substrate by identifying the at least one of the modulus of elasticity, the thickness, and the distribution associated with the one or more damping elements as a desired structural parameter:
• and if it is determined that the first performance data set does not satisfy the predetermined threshold, adjusting one of the at least one operating parameter and the modulus of elasticity, the thickness, and the distribution associated with the one or more damping elements.

One or more non-transitory computer-readable storage media having computer-executable instructions embodied thereon, wherein, when executed by at least one processor, the computer-executable instructions cause the processor to:

• define at least one of a modulus of elasticity, a thickness, and a distribution associated with one or more damping elements coupleable to a 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 at least one of the structural substrate and the one or more damping elements to generate a first performance data set, wherein the first performance data set is associated with the at least one operating parameter and the at least one of the modulus of elasticity, the thickness, and the distribution associated with the one or more damping elements;
• determine whether the first performance data set satisfies a predetermined threshold;
• if it is determined that the first performance data set does satisfy the predetermined threshold, reduce a noise level associated with the structural substrate by identifying the at least one of the modulus of elasticity, the thickness, and the distribution associated with the one or more damping elements as a desired structural parameter;
• and
• if it is determined that the first performance data set does not satisfy the predetermined threshold, adjusting one of the at least one operating parameter and the modulus of elasticity, the thickness, and the distribution associated with the one or more damping elements.
