METHOD OF DESIGNING AUTOMOTIVE SEAT ASSEMBLIES FOR REAR IMPACT PERFORMANCE

摘要

A method for designing automobile seat assemblies in which a sled test is runon a prototype seat assembly in order to obtain the necessary data to modelthe seat assembly with simulation software. A basic model of the surface ofthe seat assembly is built utilizing simulation software and tests are run onvarious parameters to determine those that are most significant to the desiredobjective of the design process. Thereafter, the software is used to build adetailed model of the seat assembly and all its elements and the significantparameters are tested further to determine those that are again mostsignificant to achieving the desired outcome. Once optimization ranges forthose most significant parameters are chosen, the prototype seat assembly ismodified accordingly. A final sled test is run on the modified prototype toverify the results and compare those results with the original sled testresults.
