Description

Technical Field

[0001] The invention relates to the technical field of rubber structure production and manufacturing, and in particular to an assembled dynamic resonator. Background Art

[0002] Dynamic vibration absorber, also known as damper and resonance block, works on the principle of attaching a mass-spring resonance system to a vibrating object. The reaction force generated by this additional system during resonance can reduce the vibration of the vibrating object. It is generally composed of a damping system, a mass block, and an installation part. It is widely used in automobiles, bridges, high-rise buildings, etc.

[0003] At present, the proportion of new energy vehicles in the market is getting higher and higher. Compared with traditional fuel vehicles, due to the absence of the roar of the fuel engine, the drivers and passengers of new energy vehicles are more likely to feel the vibration and noise of the vehicle body, so it is necessary to solve this problem and improve the NVH comfort of the whole vehicle. Adding dynamic vibration absorbers is the lowest cost and shortest cycle solution. Generally, the NVH problem of a vehicle can only be discovered after the sample car is produced, but at this time, the time from the official launch of the vehicle is very short, and the verification and debugging of the actual vehicle is often concentrated in the middle and late stages of the trial production and development of the whole vehicle, which gives suppliers limited time to develop dynamic vibration absorbers.
