Is there a trailer?
Will the vibration increase with the speed of the Cummins ISX15 CM2250 SN diesel engine?
Does vibration increase with road speed?
Does it vibrate only on specific Cummins ISX15 CM2250 SN diesel engine speeds (RPM)?
6) Is there vibration on the new Cummins ISX15 CM2250 SN diesel engine? (From the new Cummins ISX15 CM2250 SN diesel engine, after the last repair, after the equipment modification)
7) Is the vibration easy to repeat?
8) Does the other device with the same technical specifications have the same fault? (If yes, note the Cummins ISX15 CM2250 SN diesel engine serial number (ESN) and test the vehicle)
9) Are you the sole operator of this equipment? (If not, have other operators noticed the symptoms)?
Overview Vibration failures are difficult to diagnose and understand their root causes. This troubleshooting manual is designed to help you master the logical steps of identifying the source of a failure. Acceptance of vibration is highly subjective; problems that one cannot accept may be acceptable to another.
Vibration failure can be caused by many parts in the system (including Cummins ISX15 CM2250 SN diesel engine, drive components, brackets, and equipment). The cause may be passed on or produced by a point that is not obvious in the distance.
Cummins experience has shown that Cummins ISX15 CM2250 SN diesel engines are rarely the cause of operator complaints. In most cases, it is caused by the design of Cummins ISX15 CM2250 SN diesel engine bracket or various parts of the equipment. Cummins ISX15 CM2250 SN diesel engine will only malfunction if there is a lack of fire or when the components of Cummins ISX15 CM2250 SN diesel engine are out of balance.
Vibration failures that occur only at idle are most likely caused by Cummins ISX15 CM2250 SN diesel engine mounts. If the natural frequency of the Cummins ISX15 CM2250 SN diesel engine bracket is close to the ignition frequency of the Cummins ISX15 CM2250 SN diesel engine, the Cummins ISX15 CM2250 SN diesel engine will increase the normal vibration of the bracket and cause severe vibration of surrounding components when idling.
Natural frequency Natural frequency, as the name implies, is the frequency at which an object naturally vibrates. This frequency depends mainly on mass and elasticity.
Vibration type
1) Linear
a) Rotating parts
b) Torque reaction is caused by unbalanced rotating parts and cylinder ignition shock.
Can be clearly felt and observed.
Excessive vibration can cause operator discomfort and component damage.
2) Torsion-Cyclic acceleration and deceleration of rotating parts by torsional forces.
Controlled by flywheel mass and shock absorber.
Cannot be felt by the operator.
Can damage gears and splines.
3) Resonance-Parts excited at natural frequencies are actually linearly vibrating.
Resonance occurs when a system or component is excited by a linear vibration at a natural frequency.
As you approach the natural frequency of the system, the amplitude of the vibration increases. When the frequency of the excitation force (Cummins ISX15 CM2250 SN diesel engine ignition frequency) increases beyond the natural frequency of the system, the amplitude will decrease.
The amplitude of the resonance can be many times greater than the excitation force.
Vibration must be controlled by the design of the bracket (Cummins ISX15 CM2250 SN diesel engine and cab) and components.
Cummins ISX15 CM2250 SN diesel engine and cab brackets must be designed to isolate or reduce vibration transmission from Cummins ISX15 CM2250 SN diesel engine and equipment components.
For maximum isolation, the natural frequency of the stent needs to be as small as possible.
A good Cummins ISX15 CM2250 SN diesel engine bracket will reduce the amount of vibration of the Cummins ISX15 CM2250 SN diesel engine transmitted to the chassis at idle speed by at least 50%.
The hard Cummins ISX15 CM2250 SN diesel engine bracket can hardly provide vibration isolation, and may actually amplify the vibration transmitted to the chassis.
The hardness (hardness tester) and specifications of the vibration isolation pad and the weight of the Cummins ISX15 CM2250 SN diesel engine or components are the determining factors in designing the suspension system. Vibration isolation pads suitable for one Cummins ISX15 CM2250 SN diesel engine may not be suitable for another Cummins ISX15 CM2250 SN diesel engine. Also, due to the difference in weight, the vibration isolation pad specially designed for the rear of Cummins ISX15 CM2250 SN diesel engine may not be suitable for the front of Cummins ISX15 CM2250 SN diesel engine.
