Accumulation of hydrocarbon gases in near-surface cavities creates risks of gas emissions, fires and explosions. The rapid prediction and diagnosis of gas emissions is based on planetary observations from satellites of ozone concentration in the atmosphere.

P Ogin
The article addresses the issues of end connections of heat-treated precision 81 machine parts with low stiffness, especially mounted camshaft cars.

Analysis of the sliding parameters variation mechanism in engagement of gear hone teeth and parts with consideration of
The value of deformation of the gear grinding tooth depends on the position of the contact point along the tooth height; it increases by a factor of ten from the bottom contact point to the top. A model for the engagement of gear grinding teeth and parts is proposed that allows simulating the mobility of grinding teeth against gear teeth due to elastic deformation of the former and taking into account specific sliding variations in the contact point.
Simulation of a copper micro-wire drawing for electronics
In service, due to the penetration of abrasive grains into the metal, wear and flow of the tool material, the availability of contact deformation and elastic strain of the teeth of the gear wheel, especially in the case of elastic bonding agents, tooth contact does not occur in a point, but in an ellipse area. This allows to take into account the influence of elastic stress for the calculation of the geometry of gear grinding and therefore to influence the intensity of metal removal, as well as the quality and accuracy of treatment.
Volga Polytechnic Institute (Branch) of Volgograd State Technical University, Engelsa 43a, Volga, Volgograd Region, 404130, Russia. In addition, the symmetry axis of the model tooth is rotated by a certain angle proportional to the deformation value, the contact points are moved and the design values of center distance, total transfer length, curvature radii and profile pressure angles are changed.
