The vibrating force due to the combustion pressure causes torque fluctuation in the crankshaft, which is transmitted to the drive train.
It also acts upon the cylinder block as a reaction force and causes Read more Torque Fluctuation due to Combustion
Automotive Diagnosis
Source of Automotive vibration Generation
As typical examples of vibrating force in a vehicle, there are the following: combustion pressure or torque fluctuation in the engine, unbalanced tires, rough road, imbalance or joint angle in the propeller Read more Source of Automotive vibration Generation
Transmission and prevention Vibration and Noise
Methods for preventing vibration or noise are as follows:
Removing the vibrating force
Stopping the resonance
Stopping the transmission
Preventing vibration and noise
etc.
Vibration or noise can Read more Transmission and prevention Vibration and Noise
Method of Indicating Vibration, Sound, and Noise
Transmitting system
A vibration caused by a vibrating force and amplified by resonance causes the O-ring of the exhaust pipe and engine mounts to vibrate, transmitting a noise to the cabin. The passage Read more Method of Indicating Vibration, Sound, and Noise
Automotive Resonating System
If vibrating force is applied to the spring and weight as shown in the figure, vibration rapidly becomes large when the frequency of the applied force reaches a certain frequency level. This phenomenon Read more Automotive Resonating System
How are Vibration and Noise Transmitted
Basically, vibration and sound are transmitted in the same way. Let us take a look at the process of how a vibration is generated and transmitted to the human body as a vibration or a sound. Transmission Read more How are Vibration and Noise Transmitted
Automotive Vibration and Sound
When driving on a highway, if the steering wheel or the body vibrates or an unpleasant booming noise is heard from some unknown place, the driver would feel anxious not only about the discomfort but also Read more Automotive Vibration and Sound
Brake Squeal Phenomenon and Causes
There are two types of squeal: one is a high-pitched shriek and the other is a low-pitched growl. A high-pitched shriek occurs during normal braking. It also occurs during light braking on vehicles with Read more Brake Squeal Phenomenon and Causes
Vibration During Braking Phenomenon and Causes
The dashboard, steering wheel, and seats vibrate abruptly upon braking. A pulsation is felt on the brake pedal at the same frequency as this vibration. Although the frequency is similar to that of body Read more Vibration During Braking Phenomenon and Causes
Cranking Vibration Phenomenon and Causes
The body and seats shake slowly when you are cranking the engine. This vibration occurs immediately upon cranking, and stops the moment the engine has started.
Main causes
Engine torque fluctuations
Body Read more Cranking Vibration Phenomenon and Causes
