The effects of lubricate and cool technological tools on grinding stress
摘要
High-speed machining mode has a great influence on the residual stress of finished parts, and hence on the quality and durability of the products. In this connection, one of the most effective tools to reduce stress of the finished parts is to supply lubricant to the part working area in the process of machining.

Mathematical modeling of non-linear magnetic response of rigid thin disk superconductor with magnetic field dependence on critical current density
摘要
The study presents a mathematical model of magnetization harmonics for hard II-type thin disk superconductors. According to the critical state model with Jc ~ /H2 in approximation of magnetic field screening in the disk center, the authors have calculated hysteretic magnetization curves and the dependence of real and imaginary components of the first, third and fifth magnetization harmonics on voltage value of variable and static magnetic fields. Variable magnetic field amplitude has a considerable effect on magnetization harmonics amplitudes.
Effectiveness of finite element models for rolling stock engeneering
摘要
The paper considers the finite element modeling method for engineering solutions. One of the most important stages in the problem solution is how to create a finite element mesh. In this connection, the author focuses on various types of meshes. Using of these methods can reduce the analysis time and computing resources. It can also help to avoid various errors in engineering solutions.
