I believe you have heard of NVH, it is Noise (noise), Vibration (vibration), Harshness (sound roughness) abbreviation. Among them, Noise can be divided into air and structural sound; Vibration refers to the body we feel the vibration frequency (0.5-500Hz); Harshness refers to the quality of noise and vibration, is more subjective feelings.
The vast majority of parts of a vehicle will have an impact on its overall NVH performance. NVH is not a part of what many people think about in the later stages of vehicle development, but the issues that need to be considered at the beginning of vehicle S54B32 conrods development. Simply put, NVH is not only the late increase in sound-absorbing cotton or rubber bushings and other components can be resolved, more importantly, the need for vehicle structure, shape and other parts to be optimized in order to achieve excellent performance.
We are the protagonist of today's performance is not listed on the MG ZS models, the new car located in a small SUV, has a very young, stylish design, we have earlier it is static, dynamic performance analysis, my colleagues But also to give it a good evaluation. This time we will go to Shanghai Anting's SAIC Technology Center NVH laboratory on the MG ZS models S54B32 rods in the NVH design to understand.
SAH Technology Center NVH laboratory was built in June 2015, mainly for SAIC models NVH development and verification. The laboratory mainly includes four drum semi-anechoic chamber, two drum semi-anechoic chamber, gearbox NVH laboratory, the whole elimination - reverberation room, vehicle fit polo 6r coilovers vibration abnormalities laboratory and parts vibration abnormal sound test room 10 laboratories, hardware facilities in the country more advantages.
