Abstract
Analyses on stress and deformed shape of Hammer Mill Hammers (HMHs) by
using Autodesk Inventor software had been conducted. The simulation by using
impact of 21.396 N and moment force of 1.326 Nmm resulted maximum result of
Von Mises stress 153.5 Mpa and maximum displacement of 0.1695 mm with
stress impact concentrated at one point (middle part) of the HMHs surface. If
direction of impact load worked at the middle point and was distributed evenly at
the periphery part of HMHs surface, the maximum Von Mises stress value was
204.4 Mpa and maximum displacement was 0.2819 mm. Seeing from obtained
maximum Von Mises value, HMHs would not undergo failure because maximum
of Von Mises value was lower than yield strength of used material; the
manganese steel, with yield strength of 360 Mpa. Minimum values of safety factor
or both directions of impact load were 1.761 and 2.345 respectively, and they
excessed required values for a design (safety factor > 1).
