Document Type and Number:
WIPO Patent Application WO/2023/166830
Kind Code:
A1
Abstract:
A device for analyzing optimization of a load-transmitting member in a vehicle body skeleton component of an automotive vehicle according to the present invention, the device performing the following processes when setting analysis conditions for analyzing optimization (21): setting of an impact load input site 121 and a plurality of load transmission sites 123 in a vehicle body skeleton component of an optimization analysis model 120 (21a); distribution of the impact load to a plurality of withstand-load components at or below a withstand load and determination of a transmission load at each of the load transmission sites (21b); setting of a load condition for setting the determined transmission loads as impact load counterforces acting on the load transmission sites 123, and a constraint condition for constraining displacement of the impact load input site 121 (21c); and setting of a prescribed target function and a limitation condition under which displacements of the plurality of load transmission sites 123 are equal as optimization analysis conditions (21d).
