Reliability Determination and Diagnostics of a Mechatronic System

Abstract

In order to reduce the number and time of layups and to increase the period of effective operation of a mechatronic system it is reasonable to carry out predictive recovery works during one stoppage (repair) for a group of component parts with equal, close or multiple operation hours to the prior-to-failure (limiting) state. Such approach gives also the possibility to carry out recovery works with separate elements in parallel, which allows to reduce the system layup time and to increase the production output.

Design and strength analysis of mechanical rack system

“…As the construction consists of thin-walled tubing, it is suitable for the model to be constructed from shell elements [17]. In ADINA Structures Pre-Processing we created the geometry of the shell model of the rack bearing part and the geometry of the arm shell model [18,19].…”

Design and stress analysis of wheeled compactor construction

“…The least yield point value of used material was used for results and so lifespan of construction also depends on features of used material. Every manufacturer of materials used for analysing has different final features by production of steel and this fact must be taken into consideration [9][10][11][12][13][14][15][16][17].…”

Fatigue characteristics of welded high strength steel in the low cycle region of loading

“…Since, including all these factors in a test is inconvenient, inaccurate and expensive, the use of finite element method has become a powerful tool to calculate the cyclic stress-strain response of any structure or mechanical component. The finite element method is especially used in the ground vehicle industry where discontinuities of the geometry such as notches and holes produce difficulties to calculate the local cyclic stresses and strains, which are essential to predict the fatigue life of any structure or component [15,[17][18][19][20][21][22].…”
