First of all we came to the vehicle sealed laboratory, to see the vehicle sealing performance. The whole work needs to undergo simulation analysis, the standard test, subjective assessment and system debugging, a total of four stages. Of course, this is almost all the breakdown of the project needs to go through the process.
Good vehicle sealing performance can effectively reduce wind noise, improve ride comfort. Especially in the high-speed cruise, the holes, gaps and other subtle tightly sealed, with excellent sealing of the vehicle to isolate the vast majority of wind noise. Compared to other aspects of dealing with poor models, the two have a very big difference between.
In the vehicle sealed laboratory site placed a MG fit polo 6r coilovers for sale and a pair of standard models. Through the engineers on-site test we can see, MG QS air tightness can be as low as 56SCFM (the lower the value of the better), while the standard model was 95SCFM, the advantage is very obvious. The new car in the design of the early through the CAE analysis, the vehicle sheet metal slits were optimized, the body up to more than 100 road coating process and body opening and closing parts best coilovers for polo 6r of the double seal and other design are the cornerstone of good performance.
Talking about the body structure, perhaps many of my friends think that this is safety-related components, and NVH and not much relationship, it is not true. As I mentioned above, NVH is started with vehicle research and development, not a halfway monk members. Engineers in order to obtain the best vehicle NVH performance, naturally the body structure of the hands and feet. Do not believe? Then please continue to look down.
I believe everyone in the middle school physics class already know - the sound propagation speed in the air than in the solid slower. And SAIC engineers and therefore in the MG ZS fit VW Polo 6R Lowering Kit 20 position of the whole car with a cavity cut off the design, through the air characteristics to block the cavity transmission path to slow down the transmission of noise. In addition, the engineers also used PU foam filled in the thickness of 3mm EVA material (ethylene - vinyl acetate copolymer) and the body sheet metal between, to achieve the purpose of blocking noise.
