Innovative ways to improve machines for preliminary work given the needs of the modern construction industry

Abstract

The bulldozer-ripper is the main machine during preliminary work. The creation of high-performance machines is carried out in two directions: the production of fundamentally new working elements and machines based on the use of fundamental scientific achievements and the improvement of existing working elements, and traditional type machines that are in operation. The creation of working elements for ripper-picks is a perspective development direction of machines designed for ripping frozen and hard soils. They would make it possible to significantly increase the productivity of ripping work through the rational use of the base machine traction force. We applied the superposition principle of the impact on the working medium of several factors concurrently for this, such as static and dynamic loads, through the energy accumulation and its subsequent use to create a high-speed power impulse on the cutting edge to ensure the preliminary formation of the compressed zone in the soil massif. This will lead to the power intensity reduction of the static load on the soil element separation.
