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.
