Cars undergo strict testing before leaving the factory, so what tests are done? Today,Jinghuan Environment Acoustics will take you to discuss some necessary laboratory tests related to automotive NVH (noise, vibration, and stiffness).
Acoustic laboratory: Conduct noise testing and analysis, including identification of noise sources, analysis of noise characteristics, and evaluation of noise control measures. It is generally called an anechoic room.
Vibration laboratory: used to test and evaluate the vibration performance of mechanical systems, equipment or products, including vibration characteristic analysis, vibration transmission path analysis, and vibration control measures evaluation.
Strength laboratory: used to evaluate the stiffness and strength performance of materials, parts and structures, including Tensile testing, compression test, bending test and torsion test
Modal analysis laboratory: used to determine the modal parameters of a structure, including natural frequency, mode shape, and damping ratio, to evaluate the dynamic characteristics of the structure.
Simulation laboratory: used for conducting virtual simulation experiments, analyzing and predicting the noise, vibration, and stiffness performance of products under different working conditions through computer simulation.
Environmental laboratory: used to simulate NVH performance under different environmental conditions, such as temperature, humidity, altitude, and vibration, to evaluate the performance of products in actual usage environments.These laboratories can provide comprehensive NVH testing and analysis services, helping enterprises improve product design and optimize NVH performance to meet customer needs and standards.
