Patent ID: 8560288

Claim:
An apparatus for creating an analysis model of an elastomeric material member, comprising: a shell element creation unit that creates shell elements on the elastomeric material member having a strong nonlinearity and sandwiched between a first member and a second member, the shell element creation unit creating first shell elements defined by first nodes on a first contact surface of the elastomeric material member contacting the first member and then creating second shell elements by defining second nodes having the same interval as an interval between the first nodes on a second contact surface of the elastomeric material member contacting the second member, the first and second shell elements created independently from meshes created in the first and second members on surfaces of the first and second members that respectively faces the first and second contact surfaces of the elastomeric material member; a spring element creation unit creating a spring element between each of the first nodes and a second node corresponding to the each of the first nodes; and a spring constant identification unit for identifying a spring constant of the spring elements, the spring element creation unit creates spring elements between nodes of the created first and second shell elements to create a test model, the spring constant identification unit identifies the spring constant of the test model using an initial value found from material test data of the elastomeric material member and the node interval.
