<p><P>PROBLEM TO BE SOLVED: To provide a steam hole arrangement determination method of a laminated rubber that can decide the arrangement of the steam hole that can shorten a vulcanization time. <P>SOLUTION: An initial value of a parameter to fix positions of a plurality of steam holes is set up (104) and an FEM model in which the laminated rubber in which the plurality of steam holes are formed at the positions defined based on the set parameter is divided into the finite number of element is generated (106). The vulcanization condition is given to the generated FEM model, the heat transfer is analyzed, the time change of a temperature of each element that composes each rubber member of the FEM model is forecasted (108), and the arrival time until the most delayed part reaches the predetermined temperature is obtained (110). When the end condition of the optimization is not filled (112), the parameters to fix the position of the steam hole is changed (114) and the processing is repeated. <P>COPYRIGHT: (C)2012,JPO&INPIT</p> |
