Patent number: 11494525Abstract: A method for analyzing a heat exchanger includes a structural model creation step (S1) of creating a structural model of a heat exchanger; a iron-linear model creation step (S4) of creating a iron-linear model in which a non-linear spring element in an out-of-plane direction, in which a load is generated only at me time of contact between a heat transfer tube and an anti-vibration member, is applied to an opposing portion between the heat transfer tube and the anti-vibration member in a structural model, and a load distribution acquisition step (S5) of performing analysis in which a load in the out-of-plane direction is applied to the non-linear model to acquire load distribution of the heat exchanger from a value of the load in each opposing portion.Type: GrantFiled: October 23, 2017Date of Patent: November 8, 2022Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Masatsugu Monde, Naoki Ono, Tomohito Nakamori, Masaaki Katayama, Ryoichi Kawakami, Masahito Matsubara, Tomonori Mineno

Patent number: 10935232Abstract: A vibration damping structure for a heat-transfer tube bundle including columns arranged at an interval and each composed of a plurality of heat-transfer tubes curved in a common plane and arranged in parallel to each other. The vibration damping structure includes a first vibration damping member and a second vibration damping member disposed between the columns so as to intersect the array direction of the columns. The first vibration damping member and the second vibration damping member are disposed at different positions in an axial direction of each heat-transfer tube, and thicknesses of the first vibration damping member and the second vibration damping member in the array direction are larger than an average value of a clearance between the columns under operation.Type: GrantFiled: July 21, 2017Date of Patent: March 2, 2021Assignee: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Masaaki Katayama, Masatsugu Monde, Kazuo Hirota, Naoki Ono

Publication number: 20190179986Abstract: There is provided a method for analyzing a vibration damping structure in which a tube bundle disposed in a fluid is supported by a vibration damping member disposed in a gap between tubes included in the tube bundle. The method includes a model making step of making a FEM model corresponding to the vibration damping structure, an error setting step of setting an error parameter for a parameter relating to an element included in the FEM model, and an analysis step of performing structural analysis by a finite-element method using the FEM model in which the error parameter is set.Type: ApplicationFiled: July 21, 2017Publication date: June 13, 2019Applicant: MITSUBISHI HEAVY INDUSTRIES, LTD.Inventors: Masatsugu Monde, Naoki Ono, Masaaki Katayama, Daisuke Sato
