Mechanical Design and Evaluation
Developing hardware prototypes is an expensive and time consuming
process. To streamline the development process, RotoSub Labs use a
technique called Virtual Prototyping, allowing fast iterations
using 3D models and simulation tools prior to manufacturing.
During the Virtual Prototype phase, 3D models are developed
based on the desired characteristics and performance of the
In addition to normal fan design considerations, the fan is
also designed to allow for correct movement of the blades to
generate anti-sound. Modal analysis tools are used to
ensure that desired movement is achieved in all relevant
This is an iterative process, where many slight alterations
are evaluated, to get the best possible basis for the next
step - the physical prototype.
When the evaluation of the virtual prototype is satisfactory, a
physical prototype is manufactured for further evaluation.
Once completed, a laser vibrometer is used to verify that the
simulations corresponds to actual behaviour of the physical fan.
The laser vibrometer scans the fan blades and measures the movement
mapped in the frequency domain.
