ODS Testing

Operating Deflection Shape analysis is another method we use to troubleshoot “why” and “how” vibration is occurring.  Using ODS we can visualize the movement of an entire machine, or diagnose a structural problem. ODS is a collection of vibration readings in reference to each other. The direction and placement of the sensor is critical in determining how a bearing pedestal may be moving in relation to another bearing etc. The typical results found are structural problems (which are identified) and resonance problems. With a 3D model we can show you the way that your machine is actually moving as it vibrates in order to identify areas where the structure may need more support.
