The system analysis methodology is an important exercise for vibration isolator performance. This critical endeavor is the starting point for mounting strategies. An analysis like this can be applied to any number of machines and mechanical systems. For purposes of illustration, we will consider how system analysis methodology is used for an engine.
In an engine, engineers analyze the following components:
All of the data from that analysis will inform this process.
If you were submitting specs to Parker LORD, all of the above would be required data points for an expert recommendation on vibration isolation methods and parts.
Sometimes, layouts and drawings will already include this data. That can be used instead of a manual entry.
This data is then used to create an engine analysis model.
The engine analysis model is crafted in various ways. Parker LORD has proprietary software, called Harmony, that will intake the relevant data and delivery models. The analysis will take into account things like static and dynamic loads, linear or nonlinear mount properties, and more. Once the model is built, the mount analysis begins. Engineers will use the data to perform static and dynamic analyses:
Application mode—shock inputs, ground inputs, maneuvering loads—is also analyzed, depending on the intended use.
Once the analysis is completed, mounts are selected. Recommendations are made that include:
One of the most valuable outcomes of this analysis model is transmissibility plotting. Knowing the transmissibility value will inform the mount that a client should use. The goal is to conclude this process with a well-isolated system.
Qualified engineers can analyze and design any part for vibration and motion control needs.
Vibration mounts are installed in numerous places on a machine or mechanical system. They increase the lifespan of valuable and essential machines and ensure safe ongoing use.
