Publication number: 20130255238Abstract: A catalyst converter having a retaining mat with a thickness wherein the apparent density during assembling becomes 0.25 g/cm3 or more and less than 0.51 g/cm3 and the outside diameter D1 of a catalyst retainer is set according to interference of the retaining mat in passing through a press-in tool and interference of the retaining mat after being pressed into a retaining tube. The retaining mat is formed of a non-expandable inorganic fiber sheet. A pressing force moves the catalyst retainer in the axial direction with respect to the retaining tube while the catalyst converter device is used with the length L2 along the longitudinal direction of the catalyst retainer in the retaining mat wound around the catalyst retainer being set longer than the winding diameter D1 of the retaining mat around the catalyst retainer so that a retaining force R greater than the pressing force F can be secured.Type: ApplicationFiled: March 13, 2013Publication date: October 3, 2013Applicant: HONDA MOTOR CO., LTD.Inventors: Atsushi MURAKAMI, Kensuke HONMA, Kazuhisa MAEDA

Patent number: 8321185Abstract: There is provided a model that can evaluate properties of viscoelasticity and also rubber elasticity of an elastic material. A correlation equation between stress and strain that is calculated from: a correlation equation between stress, strain, elastic modulus and relaxation time, calculated based on a Maxwell model in which an elastic element and a viscous element are placed in series; and a correlation equation between strain and elastic modulus, including different moduli depending on properties, the correlation equation between stress and strain including different moduli depending on said properties as parameters is output as a stress-strain curve formula. There is one feature in finding a correlation between the strain and the elastic modulus, and this allows a large deformation behavior of an elastic material having properties of both rubber elasticity and viscoelasticity to be expressed with high quantitative characteristics on simulation.Type: GrantFiled: October 27, 2009Date of Patent: November 27, 2012Assignees: Nitto Denko Corporation, Hiroshima UniversityInventors: Kazuhisa Maeda, Shigenobu Okazawa, Koji Nishiguchi
