| 總結: | In recent years, dummy development for crash test have grown rapidly to decrease
the fatalities during crash. These dummies are generated based on anthropometric
database consisting of several percentile. Anthropometric data is very important
in terms of ergonomics to specify the physical dimensions for product design
and dynamic behavior for user safety. The development of dummy models starts
from rigid body models to deformable models which is then adopted into finite
element models for more accurate and detailed results in doing analysis. Using
the numerical method (FEM) to evaluate crash test has increase the cost saving
and accuracy in crash analysis. An average anthropometric of 100 Malaysian
females with 59 anthropometric data is modeled using Solidworks 2010. The parameters
of boundary conditions for the model are conducted in the preprocessor
called GiD, before the input file from GiD is run using an explicit finite element
program suite called Impact. The dummy model is set in sitting position and
crushed with a chair at velocity 15.3ms−1 from behind. The deformation which
includes as displacements, velocity and acceleration are presented in this research.
The results show that the head experienced the bounce and highest displacement.
This model can be further complemented for the family of Malaysian Anthropometric
Test Dummy in computational test dummies to improve safety for local
passengers. |
