“…The spring is to operate a definite number of cycles through a deflection s measured as additional compression from 0 L . The application of a similar optimization procedure, as applied above, for the fatigue condition (6) Hence, these expressions determine the optimal spring, acceptable from the viewpoint of fatigue life criterion (6).…”

“…The solutions for helical springs with circular cross-sections in terms of series of appropriate Legendre functions in toroidal coordinates were found by [Freiberger, 1949] and [Henrici, 1955]. The standard design formulas for helical springs [EN 13906, 2013[EN 13906, , 2014, [Meissner et al, 2015] are based on these results.Consider for the beginning the helical spring with a circular wire. The analysis of a cylindrical helical spring is based on the following conventional spring formulas for springs.…”

The spring is the widespread resilient element which is used in the industrial machinery and automotive systems, as diesel fuel pumps, valvetrains, brakes, suspensions, seats, doors and control elements. For reducing impact events in some heavy trucks and railroad cars primarily, helical, or coil, springs are applied. In some vehicles torsion bars are used instead of the coil springs. The reduction of weight of the suspension springs causes the decrease of unsprung mass of the axle and has a positive influence on the comfort, traction and steering properties of the car. The development of modern passenger cars has highlighted a trend towards reduced package space for suspension components in order to maximize package space for occupants and loads. Such requirements lead to reduction in spring dimensions and wire cross-section. Springs can be found in high-precision testing devices, where springs play the role of energy harvesters. The efficient design procedures for spring elements are based on the modern simulation and optimization methods. The design formulas for linear helical springs with an inconstant wire diameter and with a variable mean diameter of spring are presented. Based on these formulas the optimization of spring for given spring rate and strength of the wire is per-formed.

Critical security systems for energy supply depends upon energy storage by batteries or the cable supply. "What if this self-sufficient must be supplied?" The main focus of the paper lies on construction and adaptation of an impulse coupling which generates a sufficient voltage to supply to a monitoring system by using rotational energy at lower rotational speed and thus making a system self-sufficient energy supply system. Another main focus lies in the optimization of the failure rate in a system because of mechanical components. In this research project the theoretical approaches are checked by a suitable parameter frame in a real system. A fault tree analysis (FTA) was pulled up for the evaluation of the failure rate, to show potential failures and to validate these, we carried out other simulations by means of the Finite elements method (FEM)
