General information and guidelines.
This document establishes methods and guidelines for measuring and classifying mechanical vibrations of reciprocating machines. In general, this document focuses on the vibrations of the main structure of the machine.
The vibration indexes given are mainly used to classify the vibration of the machine to avoid problems with the auxiliary equipment attached to it.
Recommended measurement and evaluation criteria.
Typical characteristics of reciprocating machines are oscillating mass, periodically varying output (input) torque, and pulsating forces applied to the pipeline.
These characteristics cause considerable alternating forces in the main support and vibrations in the main frame, the magnitude of which is often higher than that of rotating machines.
Due to the design characteristics of the machine, reciprocating machines are more stable than rotary machines over their service life.
In reciprocating machines, vibrations measured on the main structure of the machine and quantified according to this document give only the stresses and
The general concept of vibration state. For example, the torsional vibration of rotating parts cannot generally be assessed by measuring the structural parts of the machine.
The damage caused by the standard values obtained from experience mainly occurs in the parts connected to the machine (such as turbochargers, heat exchangers,
Controllers, filters, pumps, etc.), components that connect the machine to peripheral equipment (such as pipes) or monitoring instruments installed on the machine (such as pressure
The damage assessment by vibration depends critically on the design and installation of these components.
In some cases, it is necessary to carry out specific measurements on certain parts of the machine to ensure that the vibrations are within the permissible range.
It can happen that even if the measured values are within the standard allowable values, problems may occur due to the fact that the components installed in various machines are very different.
These problems can and should be corrected by special "local measures" (e.g. by eliminating resonances). Nevertheless, experience has shown that most
In some cases, it is possible to specify a measurable quantity that describes the vibration state and give a guide value. This means that the measurable variable and the guide value can be
For quantitative purposes, the term "vibration" will be used when describing the vibration of reciprocating machinery in a simplified manner.
Intensity of movement".
The vibration of a reciprocating piston machine is not only affected by the characteristics of the machine itself, but also to a large extent by the foundation.
As a vibration source, vibration isolation between the machine and the foundation may be necessary, because the vibration response of the foundation will have a considerable impact on the vibration of the machine itself.
These vibration conditions also depend on the transmission characteristics of the machine's surrounding environment, so they cannot be completely determined by the vibration of the machine itself.
The document only serves as a guide with regard to the environmental impact of the machine.

1 Scope
This document uses the method of measuring the vibration of non-rotating and non-reciprocating parts of the whole machine to evaluate the mechanical vibration of reciprocating machines.
This includes torsional vibration and is outside the scope of this document.
This document applies to rigid or elastically mounted reciprocating piston machines with a rated power greater than 100 kW, such as marine propulsion engines, ship
Use auxiliary machines, diesel generators, reciprocating pumps and locomotive diesel engines.
This document is generally used for operation monitoring and acceptance testing. It is also used to evaluate whether the vibration of the machine affects the equipment directly installed on the machine.
Have adverse effects.
This document also applies to mechanical systems involving driving or driven reciprocating machines, which are to be assessed according to the relevant standards and classifications.
It is recognised that the application of this document is limited when considering the effects of internal machine components, such as valves, loose pistons, piston rings, etc.
problems are unlikely to be reflected in the measurements, and their identification requires research techniques outside the scope of this document. Noise is not covered in this document.
