8.2.3 Application
Fatigue and Life Prediction of Piston Rod
A piston rod lying in the x-y-z coordinates as shown in
the figure is made from a material that has the Young’s modulus of
2
11
210 N m and Poisson’s ratio of 0.3. The rod is subjected to a
force from the piston pin with the magnitude of 20,000 N in the
negative y-direction. We will use ANSYS through its Workbench
to estimate the life span of this piston rod.
