Simulation of translational and rotational motion assuming the structure as a rigid body structure
Challenge: Identification of rotational motion which is hardly measured by physical test
In general, physical test is able to measure only translational motion but rotational motion of a structure, which doesn't allow us to identify the motion of a structure precisely if rotational motion involves.
This creates pains for the following occasion.
- Simulation for engine auxiliaries parts vibration and/or fatigue strength under running condition
- Understanding the drive shaft motion on a vehicle
- Banding performance prediction of a printing machine
How to resolve pains:
In the above mentioned cases, the prediction of rigid body motion of arbitrary points is available when the structure is assumed to be a rigid body.
ESTECH.Rmotion predicts 6 DOF rigid body motions (translational X 3, rotational X 3) and eliminates errors as much as possible.。
Strength of the Software
- Elastic deformation of a structure is calculated by recomposing the motion of the measured points by processing predicted rigid body motion.
- Motion data is calculated at any point other than measuring point by extrapolation assuming the structure is a rigid body.
- Application of least-square method yields highly accurate output with minimum experimental error as much as possible
- Inertia properties are also predictable from the calculated rigid body motion by using ESTECH.[ I ]property.
- The transfer function synthetic model is able to be developed when a connecting plane is assumed to be a rigid.
