    摘要: A muffler shell (1) for use in an exhaust system of a vehicle comprises an inner metal sheet (13) and an outer metal sheet (10). The outer metal sheet (10) is arranged to enclose the inner metal sheet (13). The muffler shell further comprises a vibro-acoustical dampening material (14) sandwiched between the inner metal sheet (13) and the outer metal sheet (10). Both the inner metal sheet (13) and the outer metal sheet (10) are corrugated sheets made of stainless steel having a thickness in the range of 0.15 mm to 0.30 mm. The vibro-acoustical dampening material has a thickness (T) in the range of 4 mm to 8 mm and a density in the range of 130 kg/m3 to 160 kg/m3.

    摘要: A noise elimination method based on sound ray refraction theory and the muffler thereby are disclosed. The method use s low temperature refrigeration system (2) to form a temperature gradient inside and outside the chamber of the muffler, and the temperature inside the pipe wall of the chamber is higher than the outside. The temperature gradient may force sound ray to reflect towards the low temperature direction, so the noise of the system may be captured and reduced. The muffler comprises a housing (1) whose inner wall is laid with a sound absorbing structure (4), and on the outer wall of the housing (1) is provide a low temperature refrigerating system (2). The system covers at least of the area of the outer wail of muffler housing (1) and combines with a temperature control system (3) to realize quantitative control of the temperature gradient. The muffler improves the noise-absorbing effect of the existing muffler effectively.

    摘要: Provided is a shield in which a flexible member is interposed between two metal plates; still unfilled spaces that are not filled with the flexible member are secured, so that the shielding properties are improved by air layers. The shield 1A includes two metal plates 2, 3 disposed to face each other, and a plate-shaped flexible member 4 interposed between the two metal plates. Each of the two metal plates 2, 3 has a plurality of protrusion-depression structures. Gap-forming means is provided to form gaps of a width greater than the thickness of the flexible member 4 between the two metal plates 2, 3 when the flexible member 4 is interposed therebetween. Unfilled spaces (5) that are not filled with the flexible member 4 are provided between the two metal plates 2, 3.
