Jun 11, 2020 · 1 Introduction Laminated steel sheets sandwiched with a polymer core are increasingly used for automotive application due to their superior vibration and sound damping properties [1] . Two types of laminated sheets, i.e. light weight laminated steel with a thick polymer core (SPS) and laminated vibration damping steel (LVDS) with a thin polymer adhesive core have been utilized in automotive A New 3D Method for Reactor Core Vibration Based on

  • AbstractIntroductionMethodsComparison of 2D and 3D MethodsInfluence of Air Gap Number on UHV Shunt Reactor CORE VibrationConclusionData AvailabilityAcknowledgmentsA new three-dimensional (3D) analysis method is proposed as the existing two-dimensional (2D) method has low accuracy in analysing the vibration characteristics of oil-immersed shunt reactors, such as ultrahigh-voltage (UHV) shunt reactors. First of all, a set of 3D laminated coordinate systems was defined based on silicon steel lamination rules, in which the anisotropy of magnetic properties for laminated silicon steel in the rolling direction (RD), the transverse direction (TD), and the lamination direction (LDDamping Analysis of Unidirectional Glass Fiber Composites Nov 01, 2006 · The article investigates the damping of unidirectional glass fiber composites with a single or two interleaved viscoelastic layers. The experimental damping characteristics are derived from flexural vibrations of cantilever beams as a function of the fiber orientation.

    Characterization of the Mechanical Properties of a High

    Sep 01, 2019 · In this study, the mechanical properties of a high-strength laminated vibration damping steel sheet (LVDSS) with stretch-dominated deformation behavior were characterized and successfully applied to formability prediction. The high-strength LVDSS was fabricated with dual-phase 590 steel sheets as outer skins and polymeric adhesive layer as a core via roll bonding. Experimental and Numerical Investigations of the Bending Abstract. Laminated steel, as studied in this work, is a sheet metal product that consists of two steel sheets with a relatively thin polymer layer between them. It has been developed for applications requiring sound and vibration damping. The objective of the study concerns bending operations, in particular how tooling and sheet geometry, material properties, and process parameters affect the shape and Finite element analysis for delamination of laminated Jun 01, 2007 · The material structure of laminated vibration damping steel sheet (LVDSS) was introduced in detail. An interface cohesive model between the skin sheets was developed by using a contact/interface approach, and the model was applied to simulate T-peel and lap-shear processes of LVDSS. The interface contact stress distribution during the T-peel and lap-shear processes is

    Sheets with vibration damping qualities can be made of steel sheets enclosing a viscoelastic plasticcorelayer (see Figure 17). The vibration energy of the oscillating coversheet is converted into heat. For automotive lightweight constructions, sandwich sheets with a noise-absorbent behavior are highly useful in the engine bay. SAE MOBILUSMar 03, 2003 · Mignery L. A.
