What kind of vibration does a harmonic balancer cause?
A harmonic balancer only effects unbalanced engine vibration if it contains a counterweight. This is referred to as an external balanced engine. Today the Ford Power Stroke and Chevy Duramax fall into this category.
How is the frequency of a vibration determined?
Frequency is RPM times order, divided by 60 (cycles per second). An order is how often a vibration event occurs during one revolution of the crankshaft. In a four-stroke engine, the primary order is half the number of the cylinders. This is because only half the cylinders fire during one revolution of the crankshaft.
Which is an example of a harmonic motion?
Harmonic motion refers to the motion an oscillating mass experiences when the restoring force is proportional to the displacement, but in opposite directions. Harmonic motion is periodic and can be represented by a sine wave with constant frequency and amplitude. An example of this is a weight bouncing on a spring.
What kind of vibration does steering column make?
The resonance or frequency of the steering column structure is generally in the 28- 40Hz frequency range. This can be excited when a high second order tire is connected to the front suspension. Due to the higher frequency, this vibration feels more like a buzz than a shake.
Is there a way to accelerate a vibration test?
Using vibration test acceleration, a product can be tested for years of service in a fraction of the time. Depending on the vibration environment, the test acceleration can be performed in one of several ways. Today, the fatigue damage spectrum (FDS) is a common method to accelerate a random vibration test.
When does a bad CV axle cause vibration?
The axle shaft, then, connects the outer and inner CV joints. Bad CV Axle may create inordinate vibrations when the vehicle is running at higher speeds of around 88kph. There are several possible reasons behind a bad CV axle. Here are some of the possible causes of a bad CV axle
How does fluidampr balance engine harmonics and vibrations?
Fluidampr and their parent company Vibratech TVD have studied at length the cause and effect of harmonics and vibrations that can harm engines. “There’s a lot of confusion out there that people think the harmonic balancer helps balance the engine — it doesn’t, that’s all your reciprocating mass.
