Cars are rigorously tested before leaving the factory, so what tests are done? Today, Static Environmental Acoustics will discuss with you some must-do test rooms related to automotive NVH (noise, vibration and stiffness).

Acoustic test room: for noise testing and analysis, including noise source identification, noise characteristics analysis and noise control measures evaluation, etc., generally called an anechoic chamber.

Vibration test room: used to test and evaluate the vibration performance of mechanical systems, equipment or products, including vibration characteristics analysis, vibration transfer path analysis and vibration control measures evaluation.

Strength test room: used to evaluate the stiffness and strength performance of materials, parts and structures, including tensile tests, compression tests, bending tests and torsion tests.

Modal analysis test room: used to determine the modal parameters of the structure, including natural frequency, vibration mode and damping ratio, etc., to evaluate the dynamic characteristics of the structure.

Simulation test room: used for virtual simulation tests, through computer simulation analysis and prediction of the noise, vibration and stiffness performance of products under different working conditions.

Environmental test chambers: used to simulate NVH performance under different environmental conditions, such as temperature, humidity, altitude and vibration, to evaluate the performance of products in actual use environments.

These laboratories can provide comprehensive NVH testing and analysis services to help companies improve product design and optimize NVH performance to meet customer needs and standards.
