Abstract

Computer applications modeling finite element universe bus seats are technical
topics. Then, skeletal model starting stiffness was analyzed using simulation to meet the
European tilt safety requirement ECE R66. As a result, the skeleton's initial volume and
hardness are higher. Reduce the volume of the passenger car frame by performing a
thickness reduction in the conventional manner until skeletal deformation reaches a safe
space. continuing to improve by altering the structural skeleton's design at deformationaffecting positions. Results showed improved volumes decreased by 5%. However, this improved method is not really optimal. Conduct simulation experimental design using
optimization problems with an empirical regression equation from SPSS. applying Matlab
GA's genetic algorithms to the empirical regression equation. Results achieved as the total
volume of the selected variables decreased 18.5% compared to the prior optimization.
