## Simulation of the power skiving process for cutting an internal gear with modelling of undeformed chips

Aim. The aim of this paper is to create a 3D model of the undeformed chips produced during the cutting of an internal gear ring. By modelling the power skiving process, it is necessary to investigate the influence of various geometric and technological parameters on the thickness and cut area of the chips produced. Method. By simulating the gear turning process, it is possible to reproduce the cutting of the gear teeth and accurately determine the geometric parameters and the shape of the undeformed chip at each moment.

## Impact of traffic volume and composition on the change in the speed of traffic flow

The problem of the change in the speed of traffic flow at different traffic volumes and compositions is researched in this study. The section of the road network with different geometric parameters (descent, ascent and horizontal section) was chosen for the study. The method of investigation of traffic flow`s speed and factors which have an impact on the reduction of road network capacity are analyzed.

## Structural and Kinematic Synthesis of the 1-DOF Eight-Bar Walking Mechanism with Revolute Kinematic Pairs

Problem statement. The use of existing and the most widespread drives (wheeled and caterpillar one) is sometimes limited by complicated operational conditions while moving on rough terrain. The mentioned drives require a relatively flat surface to be operated effectively. A rocky or a hilly terrain imposes the demand of the use of alternative types of drives, in particular, walking ones.

## Structure and Kinematic Synthesis of Crank-and-slider Walking Mechanism in Order to Ensure the Prescribed Path of Supporting Foot Motion

The prospects of usage of walking drives in mobile robotic systems are overviewed. The structure of crank-and-slider mechanism was synthesized on order to ensure the prescribed motion path of the supporting foot. The problems of kinematics of crank-and-slider mechanism are considered and the equations of the supporting foot motion are deduced. The geometrical parameters of the walking mechanism are determined taking into account the advanced values of step length and foot raising hight.
