Vibration Control Solutions

Vibration problems are commonly encountered in heavy-use industrial equipment. At Acuren, we utilize and implement five basic principles to control vibration: force reduction, mass addition, tuning, isolation and damping.

Before proceeding with a vibration control method, our field experienced professional engineers perform a comprehensive evaluation of the system, including force inputs and system natural frequencies. This allows us to design and apply the appropriate solution in a timely fashion.

Our training and experience have helped us solve vibration problems from paper mill components in China to mining equipment in the Rockies.

SubjectDescription
PrinciplesThe reduction and/or isolation of a system's vibration by changing the stiffness, damping or mass of a system.

Force and vibration principles are utilized to modify existing conditions to change current vibration levels (Vibration analysis and structural analysis are typical starting points)
How is it used and for what purpose?Typically the structure is modified by changing one of 3 things:

> Changing stiffness in the system by adding/removing/moving bracing
> Increase damping by adding or changing springs , pneumatics or other damping devices
> Change the mass (or the center of mass) of the system by adding/removing weight

Goal is to reduce the vibration amplitudes to a level that does not have a negative effect on the system or its components.

Where vibration created by a process leads to undesirable outcomes (i.e. vibration in a paper machine is causing sheet breaks).

Vibration control systems can be used on any piece of equipment whose vibration causes damage to itself and/or other pieces of machinery
Applicable Codes and StandardsVarious, depending on application.

CMVA, ASTM, ASME
Form of reportAfter a thorough study of the system and current vibration levels, a FEA (Finite Element Analysis) is completed and different methods of vibration isolation and/or reduction are tested in the FEA model. These results are then presented to the customer in the form of a report, usually with several different options at varying levels of effectiveness and cost.
AdvantagesReduce maintenance costs and downtime associated with excess machine vibration.
LimitationsStructural modifications are often required and these can be complex to design and implement.
