Abstract :
For the purpose of realising the impact force
on an elastic half-space wheel made of steel, a dynamic
response analysis is established in terms of finite element
analysis. Moreover, the finite element analysis is used for
quantifying the maximum impact force in addition to
detecting the value of the elastic modulus of the wheel.
The research objective is to analyse the maximum
acceleration of the wheel throughout the impact force
process. However, the main affecting factors are the
elastic modulus symbolled by (E), impact height
symbolled by (h), as well as ratio of the Poisson
symbolled by (σ) for the half-space, based on Palmgren
empirical equation. In terms of the finite element method
the impact force process is simulated at several Poisson's
ratios and elastic modulus on the same wheel at several
impact heights. Later, a diagram termed MAP, and the
fitting equations of the correlation between the affecting
factors and maximum acceleration are acquired. The
simulation outcomes demonstrate that once the steel
wheel influences an elastic half-space, a nonlinear
quadratic relationship is obtained between the impact
height, elastic modulus, and maximum acceleration of
the wheel and elastic half-space. However, the half-space
Poisson's ratio shows a slight impact reflected into the
maximum wheel acceleration. Nevertheless, the error
that is occurred between the interpolation, theoretic, as
well simulation values was around 25%, which satisfies
the engineering conditions. As a result, it is able to be
applied in the dynamic process calculation for the impact
force process that the wheel enforces on an elastic half-
space. Moreover, the maximum acceleration of the wheel
is linked to the major affecting factors throughout the
influence force process. The elastic modulus and impact
force of the elastic half-space additionally be predicted
corresponding to the obtained fitting relationship.
