Textile-Material Model for Vibroacoustic Structural Simulation

A system comprising:

• a memory storing computer-executable instructions;
• and
• one or more processors configured to execute the computer-executable instructions to implement:
• a textile-characterization module configured to provide textile data corresponding to a textile swatch subjected to dynamic mechanical analysis, the provided textile data usable to determine of an elongation stiffness of the textile swatch in each of a course direction and a wale direction;
• a model builder configured to:
• generate, based on the determined elongation stiffness of the textile swatch, a textile-material model representing a material response of the textile swatch;
• and
• apply the textile-material model to an assembly model representing an electronic-speaker device having one or more audio components;
• and
• a simulation module configured to:
• apply boundary conditions representing strain on the textile swatch;
• apply force inputs representing audio output by the one or more audio components of the electronic-speaker device;
• simulate a vibroacoustic response of the textile swatch applied to the assembly model, the vibroacoustic response simulated based on the applied boundary conditions and force inputs;
• and
• identify, based on the simulated vibroacoustic response, frequencies that cause displacement of the textile swatch relative to surrounding areas sufficient for the textile swatch to vibrationally contact a component of the electronic-speaker device.

One or more computer-readable storage media comprising instructions that, responsive to execution by a processor, implement a simulation system to:

• determine textile-level properties of a textile swatch;
• determine, using the textile-level properties, an elongation stiffness of the textile swatch in each of a course direction and a wale direction;
• generate, based on the determined elongation stiffness of the textile swatch, a textile-material model representing a material response of the textile swatch;
• incorporate the textile-material model onto an assembly model representing an electronic-speaker device having one or more audio components;
• simulate a vibroacoustic response of the textile swatch using the assembly model based on application of:
• boundary conditions representing strain on the textile swatch;
• and
• force inputs representing audio output by the one or more audio components of the electronic-speaker device;
• identify, based on the simulated vibroacoustic response, frequencies that cause displacement of the textile swatch relative to surrounding areas sufficient for the textile swatch to vibrationally contact a component of the electronic-speaker device that is proximate to the textile swatch;
• and
• storing the identified frequencies in association with the textile swatch.
