Excessive mechanical vibration can lead to various types of problems, such as energy loss, quality defects, working environment issues, and reduced production speed. In the worst case scenario, these issues could lead to malfunctions, resulting in accidents and unplanned shutdowns.

Structural vibration analysis

In order to take appropriate measures to prevent excessive vibration, it is necessary to understand the vibration characteristics of the machine. It is crucial to identify the root cause of the problem and understand the impact of any action on the vibration characteristics of the machine (related to the load). In our structural vibration analysis service, we combine professional knowledge with advanced measurement equipment to help you achieve this goal.

Structural vibration analysis services include operational flexural mode (ODS) analysis and modal analysis. By measuring the motion of the machine under existing working conditions, we can understand the motion pattern (amplitude and phase) of each point on the machine and define the motion mode of the machine.

While conducting measurements, we combine multi-channel equipment with tools for data visualization, animation, analysis, and recording to collect data simultaneously. This can help understand the motion mode of the machine and the causes of unexpected vibrations.

Usually, the following measurements and activities are performed:

Visual inspection of equipment and structure

Initial data collection (spectrum, time, and phase)

Vibration data analysis

In some cases, collecting transient vibration data

Machine design and structural evaluation

Development of numerical simulation models

ODS vibration data collection

ODS data animation

Supplementary measurement and analysis
