Abstract:

This paper reveals the popular error and problem in optimization design of helical springs. Most of the engineers and researchers regard wire diameter d, mean coil diameter D and number of active coils n as design variables in the mathematical model of optimization design for helical springs. In fact, only two variables are independent variables in the three design variables. The dependent variable in the optimization design model influences the behavior of the systems to be optimized, which is also possible to calculate wrong results. This paper analyses relationship of wire diameter d, mean

Abstract:

This paper is a comparative between two springs such as helical and wave spring. Wave springs are precise flat wire compression springs that fit into assemblies that other springs cannot. These are used as an alternative spring for helical spring. Wave springs provide 50% reduction in spring height and axial space. They possess the same force and deflection as coil springs. They have reduced material requirements. They provide improved cost reduction. The Wave Spring has been subjected to Compression Test, Modal Analysis and Equivalent Elastic Strain Test and then compared to Helical Spring wh

Abstract:

The tension spring with initial tension is a coil spring with unique properties not found in other springs. It is often used to eliminate backlash, compensate for wear or thermal expansion, and hold parts in contact. While such tension springs have wide industrial applications, the academic literature on their properties and manufacturing is limited. Therefore, this study focuses on the computer numerical control (CNC) coiling machines commonly used to produce coil springs, and explores their process principles and the effects of settings on the geometry and initial tension of the springs thro

Abstract:

Helical springs are one of the various forms of mechanical springs that are frequently used in car and mechanical systems. During the operation of cold coiling of helical springs, residual stresses are generated in spring. These stresses are relieved by stress relieving treatment, which is carried out just after the coiling. In stress relieving slight dimensional changes occurs. As per design of springs the wire diameter, coil diameter, number of turns and modulus of rigidity of spring wire play an important role. In these studies, experimental investigation is carried for change in outer diam

Shock absorbers play a crucial role in two-wheelers by absorbing shocks from uneven terrains, improving ride comfort, and ensuring stability. This study focuses on the design and analysis of a helical spring used in the rear suspension system of a two-wheeler, aiming to enhance stiffness while minimizing stress and deflection. A comparative analysis is conducted on springs made from Inconel 600, chromium vanadium, and stainless steel to determine the most efficient material. The shock absorber spring is modelled, and finite element analysis is performed using ANSYS to evaluate its mechanical b

Abstract:

One of the tests used to determine the mechanical properties of metals is the tensile test. The results obtained from the tensile test are crucial for engineering and product design as they provide data on the strength of materials. AISI 1045 carbon steel is an alloy steel composed of iron (Fe) and carbon (C), where iron is the base element and carbon is the main alloying element. Carbon steel is also used in the manufacturing of helical/coil springs (Mobil Alvanza 2020). Coil springs are widely used in the front suspension of modern light vehicles.

Abstract:

The vibration control is an important area in the dynamic of structures that seeks to reduce the amplitude of structural responses in certain critical frequency ranges. Currently, the scientific development leads to the application of some actuators and sensors technologically superior comparing to the same features available on the market. For developing these advanced sensors and actuators, smart materials that can change their mechanical properties when subjected to certain thermomechanical loads can be employed. In this context, Shape memory alloys (SMAs) may be used for developing dynamic

This paper studies in detail the background and implementation of a teaching-learning based optimization (TLBO) algorithm with differential operator for optimization task of a few mechanical components, which are essential for most of the mechanical engineering applications. Like most of the other heuristic techniques, TLBO is also a population-based method and uses a population of solutions to proceed to the global solution. A differential operator is incorporated into the TLBO for effective search of better solutions. To validate the effectiveness of the proposed method, three typical optimi

The purpose of this study was to develop a vertical seismic isolation device essential for the three-dimensional seismic isolation design of nuclear power plant equipment. The vertical seismic isolation device in this study has a concept that can be integrally combined with a conventional laminated rubber bearing, a horizontal seismic isolator with a design vertical load of 10 kN. To develop the vertical seismic isolation device, the vertical spring and the seismic energy dissipation device capable of limiting the vertical displacement of the spring were designed and their performances were ve

Abstract:

This paper presents a new method for generating nonlinear helical spring geometries based on a rigorous mathematical formulation. The model was developed for two scenarios for modifying a spring with a stepped helix angle: for a fixed helix angle of the active coils and for a fixed overall height of the spring. It allows the development of compression spring geometries with non-linear load-deflection curves, while maintaining predetermined values of selected geometrical parameters such as the number of passive and active coils and the total height or helix angle of the linear segment of the ac

Abstract:

The maximum stress in elliptical cross-section coil springs with a certain aspect ratio becomes small as compared to the other springs used in practical machines. This article presents a simplified stress expression for designing elliptical cross-section coil springs. The stresses obtained by the present design formula are compared with those by calculated using numerical methods. It is ascertained that the present formula is applicable to design the elliptical cross-section coil springs.
