Dynamic response of vibro-impact capsule moving on the inclined track and stochastic slope

This paper shows a study on the dynamic response of the vibro-impact capsule moving up on the inclined track and under stochatistic slopes. The mathematical model of the system in moving up situation was developed and experimentally verified at three inclined angles, five levels of the magnitude excitation, and two preset friction magnitude, by means of the relative motion and the progression rate. The dimensionless model was then further established and used to examine the performance and dynamic behavior of the system. The results revealed that the slope angle, the environment friction, the excitation magnitude and frequency, all have significant effects on the moving-up ability and the dynamic response of the system. It is able to find the situation of the best forward progression where the dynamic response changed. The effect of random perturbation of the inclined angle on the system when moving to altered positions on its path was then examined. It was found that increasing the variation range will degrade the system progression and widen the distribution range of the relative velocity. The results would be useful for further studies on the design and operation of vibro-impact capsubots in various stochastic conditions.
