<P>PROBLEM TO BE SOLVED: To provide a simulation method that can forecast physical properties of the laminated rubber after the vulcanization at the large deformation. <P>SOLUTION: There is provided a physical property parameter function in which the physical property parameters after the vulcanization of the rubber member are approximated and the temperature and the vulcanization degree are made parameters (106) by making a test body which holds the rubber member with two iron plates (100), and obtaining a vulcanization degree of the test body obtained by vulcanizing in various temperature histories and a shear elastic modulus after the vulcanization (102). A temperature of each element and the time change with the vulcanization degree are forecasted by giving the vulcanization condition to a three dimension FEM model and analyzing the heat transfer (110 and 112). The physical property parameter that is calculated by giving the predicted values of the temperature and the vulcanization degree of the element of the rubber member obtained to each element are given to each element that composes the rubber member of three dimension FEM model, (114), and the structure analysis is performed by giving a boundary condition and the physical property of each element of the rubber member is presumed (116). <P>COPYRIGHT: (C)2012,JPO&INPIT |
