system. So actually, there is a big difference between operating deflections and mode shapes - we can now see that the modes shapes are summed together in some linear fashion to form the operating deflection patterns. I hope that this helps to clear up the mystery as to the differences between operating deflection patterns and mode shapes.

and operating deflection shapes. What Are Operating Deflection Shapes? Traditionally, an ODS has been defined as the deflection of a structure at a particular frequency. However, an ODS can be defined more generally as any . forced motion of two or more . points on a structure. Specifying the motion of two or more points defines a shape.

The updating procedure can be based on mode shapes or on operating deflection shapes. The operating deflection shapes correspond to the deformations that the structure suffers when it …

An operating deflection shape contains the overall vibration for two or more DOFs on a structure. An ODS therefore contains both forced and resonant vibration components whereas a mode shape characterizes only the resonant vibration at two or more DOFs [2]. Real continuous structures have an infinite number of DOFs and an infinite number of modes.
