| description | Tmck chassis is a major component in a vehicle system. It inte!:-Tfates the main
component systems such as the suspension, engine, cab and trailer. Thus it often
identified for refinement in order to develop vehicles with reduced cost and weight.
Nowadays with the capabilities of advanced computer aided design and engineering
tools, the process of chassis design in the automotive industry has been significantly
refined. The application of FEA such as structural modification and optimization is
used to reduce component complexity, weight and subsequently cost. Because the
level of model complexity can be high, the opportunity for error can also be high. For
this reason, some fonn of model verification is needed before design decisions made
in the FEA environment can be implemented in production with high confidence.
This thesis project describes the application of dynamic correlation techniques for
verification of the FEA models of truck chassis. The dynamic characteristic of tmck
chassis such as the natural frequency and mode shape will be detenllined using finite
element method. Experimental measurement has been carried out to validate the
analytically derived dynamic models. Modal testing is one of the methods that apply
the experimental technique in detennining the modes of vibration. Initial results from
both analysis show that the truck chassis experienced I >1 torsion mode for I >t natural
frequency, 1 SI bending mode for 2nd natural frequency, 2nd torsion mode for 3
rd
natural fi"equency and 2nd bending mode for 4th natural frequency. However there is a
small discrepancy in tenns of frequency. Thus. the model updating of tTIlck chassis
model has been carried by adjusting the selective properties such as Modulus Young
and Poisson ratio in order to get better a!:-Tfeement in the natural frequency between
both analysis. Finally. the modifications of the updated FE tTIlck chassis model has
been suggested such as by consider adding the stiffener. The purpose is to reduce the
vibration as well as to improve the strength of the tTIlck chassis. |
