To solve the problems of high design margin and high manufacturing cost of heavy vehicle drive axle housing,the parametric finite element model of heavy vehicle drive axle housing wheelchair Cushions is established,through the drive axle housing of key structure parameters are set for the analysis variables,the influence of the structure parameter

The consideration in the article is given to the state of objects of heat power engineering in Sverdlovsk region.Particular attention is paid to social importance of delivering of heat and power energy under climatic conditions of Sverdlovsk region.The necessity of modernization of equipment participating at delivering of heat and power energy is a

Considering the varying inertia and load torque in high speed and high accuracy servo systems, a novel discrete second-order sliding mode adaptive controller (DSSMAC) based on characteristic model is proposed, and a command GI-PRO observer is also designed.Firstly, the discrete characteristic model of servo systems is established.Secondly, the recu

Hypospadias is a challenging field of urogenital wheelchair Cushions reconstructive surgery with different techniques being currently used.Modern surgery claims that it is possible to create a functionally and cosmetically normal penis.Continuous reevaluation and assessment of outcome may have a major impact on future clinical practice.Assessment o

This article describes increasing wear resistance of 5CrNiMo die steel by more than 5 times.This effect is achieved by creating TiC-Ti-Al and TiB _2 -Ti-Al coatings on the surface of 5CrNiMo die steel.The microhardness of the formed coatings depends on which part of the structure is measured.The microhardness differs by more than 12 times in the ma
