Free-Piston Stirling Engines (FPSEs) are known for their easy maintenance, longer lifetimes, high reliability, quiet operation due to no crankshafts, and having fewer seals compared the traditional engine. Free-piston systems popular in conversion of thermal energy into electrical compatible with many types heat sources. This research paper concentrates on development a Permanent Magnet Linear ...

As was seen in previous modules, stress analysis even of simple-appearing geometries can lead to complicated mathematical maneuvering. Actual articles | engine crankshafts, medical prostheses, tennis rackets, etc. | have boundary shapes that cannot easily be described mathematically, and even if they were it would be extremely difficult to fit solutions of the governing equations to them. One a...

In this present work, the effect of input parameters viz. grinding wheel speed, work-piece speed, abrasive grain size, depth of cut, concentration of cutting fluid, and number of passes has been found on the out-ofroundness of cylindrical grinded AISI 4140 steel. Out-of-roundness is of great importance in case of shafts, axles, pistons, piston pins, crankshafts, roller bearings as out of roundn...

The installation of suitable sensors close to the tool tip on milling centres is not possible in industrial environments. It is therefore necessary to design virtual sensors for these machines to perform online fault detection in many industrial tasks. This paper presents a virtual sensor for online fault detection of multitooth tools based on a bayesian classifier. The device that performs thi...

Abstract The development of modern technologies for the restoration and hardening agricultural machine parts require a mathematical apparatus that simulates involved processes. For this purpose, models should take into account technological features process parts, including: cleaning; determination geometric indicators; surface preparation; choice technology; subsequent machining resulting surf...

The article considers the danger of torsional vibrations in ship power plants, which is recognized by leading specialists shipbuilding, engine-building and repair industries supervisory authorities – Russian Maritime Register Shipping (RMRS), River (RRR), as well foreign classification societies. There are a number factors that can lead to serious accidents due vibrations, therefore, dampers (l...

An electric car is a type of alternative-fuel vehicle that uses motors and motor controllers instead an internal combustion engine. Power provided via battery packs rather than carbon emission-based fuel. It offers variety advantages over typical engines, most notably lower local emissions higher energy efficiency. The aim this research to modify the running with engine into for transferring ma...
