The dynamics of a three-mass vibratory machine with the rectilinear translational motion of platforms and a vibration exciter in the form of a ball, roller, or pendulum auto-balancer have been analytically investigated.The existence of steady state motion... see more

Reducing the surface mass of an adhesive is one of the most important means to improve the perfection of cellular structures. One of the promising technologies in this respect is the addressed application of the adhesive on the ends of the cells. This tec... see more

The bearing structure of a covered rail wagon has been improved to enable firing from it at motion. The covered wagon of model 11–217 was chosen as a prototype. To enable firing in the vertical plane, it has been proposed to use a sliding roof, which cons... see more

A geometric model of a new method of delivering fire-extinguishing substances to a fire zone located at a considerable distance was offered. The idea of delivery is based on the mechanical action of throwing. To this end, a substance (e.g. extinguishing p... see more
