Many people may have this feeling. When they are in other cars, they feel very quiet inside the car. In some cars, the noise inside the car is a bit large, making people very uncomfortable. Why is this? Let's take a look at it together. First, where does the abnormal sound come from? 1. Design reasons: Due to the limitation of cost and technical experience, the design of the parts and components did not take into account the problem of abnormal sound and resonance at the beginning of the design. When the whole vehicle was assembled for endurance test, wherever the earthquake occurred, it was recorded and returned. Patch, here add a shock plate, where a sponge pad is finished, after a long time, a variety of abnormal sounds will appear after the patch expires. 2, the life of parts and components: due to cost constraints, the quality of parts and components is generally life, the new plastic parts of the new car parts are tight, no abnormal noise, with the passage of time, the bayonet plastic aging, bumps will produce a variety of interiors Abnormal sound. 3. Reasons for the assembly process: Due to the technical reasons of the personnel, many artificial assemblies are unstable. 4, cost reasons: some of the cheaper cars, soundproofing is very simple. 5, hanging sound: This is complicated, because the design and adjustment of the suspension itself is very difficult, without professional technicians, it is difficult to adjust the standard. Second, why are some cars very quiet? I have to mention NVH here: NVH refers to Noise, VibraTIon and Harshness. Since the above three are simultaneous and inseparable in mechanical vibrations such as automobiles, they are often put together for research. NVH is a comprehensive problem to measure the quality of automobile manufacturing. It gives car users the most direct and superficial feeling. It is one of the concerns of major automakers and component companies in the international automotive industry. Statistics show that about one-third of the problem of the vehicle is related to the NVH problem of the vehicle, and nearly 20% of the research and development expenses of major companies are spent on solving the NVH problem of the vehicle. Many large automakers have specialized NVH engineers, and their salaries are much higher than those of other engineers. There are even specialized headhunting companies around the world to dig NVH engineers for some wealthy automakers. Third, it is difficult to build a car, it is even harder to build a car! It is very important and very difficult to do NVH for a car! It is because of the long NVH process that the development cycle of a new car is very, very long. The seriousness of NVH directly affects the development cycle of a car. The development cycle of German-style Japanese cars is very long. In contrast, the development cycle of some independent brands and some Korean cars is much shorter. Maybe you think that new cars can be launched more quickly. Effectively seize the market, but in fact, learn to sink into the heart to build a car, learn to maintain their own quality standards in such a fierce competition, to a large extent can avoid many quality problems.
