Summary
Goat spine mechanics inspired a novel track design, significantly improving adhesion performance on complex terrain. This bionic structure enhances tracked vehicle stability and efficiency in challenging environments.
Area of Science:
- Biomechanics
- Robotics
- Materials Science
Background:
- Goats exhibit exceptional mobility in complex terrains due to their flexible spines.
- Spinal flexibility aids in balance and propulsion, while limbs primarily provide support.
- Goat spinal structure influences hoof-sole pressure distribution, crucial for traction.
Purpose of the Study:
- To analyze the three-dimensional force distribution of a goat's body.
- To explore optimal spinal space curves inspired by goat gait cycles.
- To design and evaluate a bionic track structure for enhanced adhesion.
Main Methods:
- Bionic prototyping based on the goat spine's optimal spatial curve.
- Functional simulation and analysis of soil contact surface structure.
- Soil tank testing to compare adhesion performance of bionic vs. ordinary track structures.
Main Results:
- Bionic track structures demonstrated superior attachment performance compared to ordinary structures.
- A single bionic curve on the track monomer's contact surface yielded the best adhesion.
- The optimal bionic structure increased adhesion by 19.22 N in soil tank tests.
Conclusions:
- Bionic curves significantly enhance track monomer adhesion performance.
- The developed bionic structure offers a new approach for improving tracked vehicle adhesion in hilly areas.
- This research validates the effectiveness of bio-inspired design for off-road mobility.
