Study

The effects of the r3vobanD on the horse's nose were determined by the ZWT GmbH tested with a computer simulation to calculate and visualize the loads on the horse's nose compared to standard leather nosebands.

Structure of the simulation

A computer simulation of a horse's head with a bridle and bit was developed to obtain quantifiable and objective measurements of the forces exerted on a horse's nose.

The validated horse's head was scanned with a 3D scanning app that uses an infrared sensor to create a 3D model of the head. In addition, a digital 3D model of a bridle was created and placed on the horse's head in the computer simulation.

Preliminary definitions

Accordingly, in both models (only leather bridle and r3vobanD® with leather bridle) the same load is applied through an identical shift - calculated from 1.5kg pulling force per side.

Computer simulation results

The maximum stresses occurring at the head are highlighted in boxes. The simulation shows that both the stress pattern and the maximum stresses are higher in the simulation without the 3D printed tape (r3vobanD®) (like the right edge: 9.26 MPa vs. 0.87 MPa).

Conclusion

This study compared the stresses on a horse's head by developing a computer simulation of a horse's head and bridle with and without an additively manufactured strap (r3vobanD®). The tensions occurring on the horse's head are reduced by +/- 60% by using the printed band (r3vobanD®). In addition, the overall strain on the bridge of the nose is reduced. The 3D printed tape (r3vobanD®) has uniform deformation and stress distribution properties. The data collected shows that pressure can be significantly reduced by using the 3D printed band (r3vobanD®) during riding and competitions. We argue that with an additively manufactured, pressure-reducing noseband, the load on the bridge of the nose can be reduced and thus the horse's well-being is guaranteed.
