Design Analysis & Development of High speed Rotating Fatigue test with integrated by twisting test. 2019-28-0053

Testing different materials for their fatigue behaviour has been a primary requirement before consider the material for use in any environment with continuous fluctuating load. There has been considerable evolution in the design of fatigue testing machines for over a century now. . In the present paper is shown a testing machine is designed and developed in such a way as to be proficient of exerting simultaneous cyclic twisting moments, such moments being uniformly distributed along the entire pawn length of the test specimen. The ratio of twisting moments can be adjusted within the range 0 to 0.5, the angular deflection of the specimen being reserved in the machine. The fatigue testing machine mostly used for industrial or a laboratory use, which are limited to performing single fatigue tests with leading cost. This paper elaborates the experimental setup of the traditional fatigue testing machine is an integrated with twisting test, to experimentally study the effect of fluctuating stresses on the material. The significance of the machine is its cheap overall price is the most important advantages of the proposed system. The machine performs fatigue test and twisting test, which provides the extreme force needed to understand the properties and behavior of materials. Fatigue occurs when a material is subjected to a repeated loading and unloading. The fatigue life is thought to be associated with the phenomenon of strain ageing. The purpose of a twisting test is to determine the behaviour a material or test sample exhibits when twisted or under torsional forces as a result of applied moments that cause shear stress about the axis. The machine is capable of doing the fatigue test in different range of loads, the applied forces are not completely noiseless, the performance of the machine followed the fringe benefit requirement mentioned in the standard. Unlike many machines that generate fatigue-alternating stresses through relocation or the rotation of the specimen on loads that are consistent across time, the design of the machine clearly displays how inertial loads due to the acceleration of the mechanical elements generated loads of alternating character which eventually causes fatigue failures.
