How and why do you measure acyclism?

Acyclisms are phenomena inherent to reciprocating machines, where in most cases, a linear motion of several pistons is transformed into a rotational crankshaft motion. The direct consequence is a variation in angular velocity, angular position or angular acceleration.

Acyclisms generate+ vibro-acoustic phenomena that are detrimental both to user comfort and to the equipment subjected to them (accelerated ageing, altered performance or functional characteristics).

Acyclism measurement is an essential means of diagnosing potential causes of failure in rotating elements. Parameters such as speed, torque, fluctuations and angular variations can be measured to identify potential problems before they cause failure. The methods and techniques used to measure acyclism depend on the access, size and environment of the product to be tested. The use of instrumentation to measure acyclism is essential to ensure safe, reliable operation of equipment and reduce maintenance costs in industries such as aerospace, automotive, energy and power generation.
