The article analyzes the prospects for the development of energy-absorbing devices with intermediate rolling elements for machines with progressive and rotational working motion. The classification of such devices is given, on the basis of which the morphological bases of such devices designs creation are offered. It is shown that the main morphological features of energy-absorbing devices with intermediate rolling elements are the type of working motion of the machine where they are used, the type of intermediate rolling elements, the type of guideline and the principle of operation. On the basis of the selected morphological features the classification of such devices is developed and presented in the form of the block diagram. The proposed classification became the basis for creating morphological bases for the synthesis of such devices structure. A morphological matrix of synthesis was formed and revealed, which gave 48 variants of possible designs of energy-absorbing devices with intermediate rolling elements for different variants of working motion. As part of the implementation for the proposed approach to the synthesis of energy-absorbing mechanisms, according to the obtained options for the disclosure of the morphological matrix. Development of new designs of such mechanisms for installation in machines with rotating and progressive working movement is executed. New designs of energy absorbing devices with intermediate rolling elements are proposed and their operation is described.
