Abstract: An assembly includes a panel member and an acoustic sink member. The panel member has a panel edge, and first and second long axes defining a plane. The panel member has a first material composition. The acoustic sink member has a body with a periphery which is coupled to the panel edge. The body has a second material composition, which is distinct from the first material composition. An acoustic impedance of the sink member at the periphery is equal to an acoustic impedance of the panel member at the panel edge, and the body has a cross-sectional profile defined by a power law.

Abstract: A battery system for an electric vehicle includes a fixed cover, and a removable cover arranged over battery modules and a high voltage distribution system. The battery system includes a busbar arranged at least partially over a region of the battery modules and under the removable cover. The busbar includes a fixed section and a movable section, or a hinge, such that the busbar can be repositioned out of the way. The support tray includes a link between the fixed and movable sections. Floating fasteners, allowing at least one of radial float and axial float are used to secure the link to the support tray, thereby avoiding safety hazards and reducing the potential for short circuits in high voltage distribution systems or conductors thereof. The floating fasteners include a head, a neck, an engagement section, and a washer, which prevent removal from a component once installed.

Abstract: The present invention addresses the problem of providing a sound insulating structure which provides a sufficient sound insulating effect even when an adhesive layer is arranged therein, and in which a shift in the frequency band where the sound insulating effect is generated is unlikely to occur. This sound insulating structure includes, at least: a sound insulating member that includes a sheet-like sheet section and plural projections arranged on the sheet section; and an adhesive layer arranged on a surface of the sheet section on the opposite side of the side provided with the projections, and the sound insulating structure satisfies the following Formula (1): E_glue/I_glue>0.5×(E_membrane/H)(1) (wherein, E_glue (MPa): storage modulus of adhesive layer, I_glue (mm): average thickness of adhesive layer, E_membrane (MPa): storage modulus of sheet section and projections, and H (mm): average height of sheet section and projections).

Abstract: The invention disclosed herein is an automotive acoustic panel including a porous sound-absorption material made from a polymer and an expanded perlite. One or more silane compounds may be coupled or coated onto the expanded perlite while a coupling agent and a chemical foaming agent may additionally be added to the automotive acoustic panel.

Abstract: A vehicle front structure includes, below a bonnet (6), a cover member (1) that covers an engine from an upper portion thereof to the side and is formed by an upper wall (30), a shroud (8) as a front wall, a rear wall (13), and side walls (11, 12) on the respective left and right sides. The cover member is formed by the upper wall, the front wall, the rear wall, and the side walls on the respective left and right sides. The front side of one of the left and right side walls is configured to have, relative to the rear side, a higher ratio of a low-rigidity member having lower rigidity than a high-rigidity member forming a main portion on the rear side.

Abstract: This storage unit is configured to store an outside-of-panel acoustic transfer function that is an acoustic transfer function involving an airborne sound that is a sound emitted from a sound source located outside a panel member and propagated through the air to an outer surface of the panel member, and a panel transmission function that is an acoustic transfer function from the outer surface of the panel member to an inner surface of the panel member. This sound transmission analyzing unit is configured to calculate, based on the outside-of-panel acoustic transfer function and the panel transmission function, an acoustic transfer function from the sound source via the air to the inner surface of the panel member.
