“…The influence of preload in energy-wise impact mitigation has seen limited interest outside of some very narrow areas. One is represented by suspension systems, present in the majority of locomotion systems, from automotive, [22], [23] to railways [24].…”

A core issue in collaborative robotics is that of impact mitigation, especially when collisions happen with operators. Passively compliant structures can be used as the frame of the cobot, although, usually, they are implemented by means of a single-degree-of-freedom (DoF). However, n-DoF preloaded structures offer a number of advantages in terms of flexibility in designing their behavior. In this work, we propose a comprehensive framework for classifying n-DoF preloaded structures, including one-, two-, and three-dimensional arrays. Furthermore, we investigate the implications of the peculiar behavior of these structures—which present sharp stiff-to-compliant transitions at design-determined load thresholds—on impact mitigation. To this regard, an analytical n-DoF dynamic model was developed and numerically implemented. A prototype of a 10DoF structure was tested under static and impact loads, showing a very good agreement with the model. Future developments will see the application of n-DoF preloaded structures to impact-mitigation on cobots and in the field of mobile robots, as well as to the field of novel architected materials.

“…magnetorheological fluid damper, MR damper) with, in parallel, a passive spring. In comparison, active suspensions are characterized by better dynamic performance but are more complex, expensive and energy consuming; the semi-active suspension seems to be the best compromise between cost and performance [1]- [4].…”

Active and semi-active suspension systems allow to obtain the best compromise between ride comfort and road holding. These systems analyze signals describing the vehicle status and react to unwanted vibrations on the basis of the control strategy. The analysis of the signals in the frequency domain can improve the control action, since incoming vibration can be properly detected. In this paper a method for the detection of incoming frequency components in real-time is proposed and is used in analyzing a Magneto-Rheological suspension system.
