dc.description.abstract | This paper studies the modelling of a vibro-impact self-propelled capsule system in the small intestinal
tract. Our studies focus on understanding the dynamic characteristics of the capsule and its performance
in terms of the average speed and energy efficiency under various system and control parameters, such as
capsule’s radius and length, and the frequency and magnitude of sinusoidal excitation. We find that the
resistance from the small intestine will be larger once capsule’s size or instantaneous velocity increases.
From our extensive numerical calculations, optimum system and control parameters are obtained for
prototype design and fabrication. It is suggested that increasing forcing magnitude or choosing forcing
frequency greater than the natural frequency of its inner mass can benefit the average speed of the
capsule, and the radius of the capsule should be slightly larger than the radius of the small intestine in
order to generate a reasonable resistance for capsule progression. Finally, the locomotion of the capsule
along an inclined intestinal tract is tested, and the best radius and forcing magnitude of the capsule are
also determined. | en_GB |
