What Does Car Resonance Feel Like?
2 Answers
Car resonance refers to the phenomenon where the vibration frequency of the car reaches the resonance frequency when driving at a certain speed, causing severe shaking of the car body. The reasons include: 1. If the car has been used for a long time, the rubber of the engine mounts may suffer from high-temperature fatigue and aging, which can easily cause resonance, and in severe cases, there may even be bumping and friction noises. 2. Engine misfire can also lead to resonance. 3. Deformation or improper installation of the engine guard plate can cause engine resonance, which is relatively common and easy to resolve. 4. Another situation is car resonance caused by issues with the idle speed control system.
I remember when I used to drive my small car, once it reached around 70 km/h, the whole vehicle would start shaking non-stop. The steering wheel buzzed and trembled in my hands, as if insects were crawling on it, and the seat swayed back and forth, making my body feel like it was gently rocking. Combined with the buzzing noise, like an old fan whirring by my ear, it was particularly distracting while driving. This usually happened when accelerating on the highway—buzzing when speeding up and disappearing when slowing down. It was likely due to unbalanced wheels or brake disc issues. When I took it to the mechanic, the technician adjusted the tire balance, and the problem was fixed. If left unaddressed for a long time, parts would wear out more easily, making the drive even more uncomfortable. So, I had to avoid that speed range while driving.
