Document Type and Number:
Japanese Patent JP7287336
Kind Code:
B2
Abstract:
An optimization analysis method for joining locations of an automotive body according to the present invention obtains optimal locations of additional joining points or joining portions for use in joining parts assemblies together in an automotive body model 31 and includes Step (S1) of obtaining a deformation form in a vibration mode occurring in the automotive body model 31 by frequency response analysis, Step (S3) of determining a load condition to be given to the automotive body model 31 in correspondence with the deformation form in the obtained vibration mode, Step (S7) of generating an optimization analysis model 51 in which additional joining candidates 53 are set at locations to be candidates for joining parts assemblies together, Step (S9) of setting an optimization analysis condition, and Step (S11) of giving the load condition determined at Step (S3) to the optimization analysis model 51 to perform optimization analysis and obtaining the additional joining candidates 53 satisfying the optimization analysis condition as optimized joining points 57.
