Influence of a New Component on a Bolted Joint 2010-36-0276
Within the development of a new vehicle, with significant body
changes and minimal modifications of powertrain layout, one of the
challenges presented to the working group came from the necessity
of a wire bracket to attend requirements of a new proposed layout.
In the current paper will be explored the definition and
development of this bolted joint, offering alternatives for keeping
synergy even facing frequent obstacles, normally inducing to
redesign.
During the development of this joint, the first configuration
tested showed self-loosening and subsequent crack at the aluminum
shield. From this start point it could be an opportunity for this
joint redesigning, but the challenge is how to do it respecting the
project constraints, parameters and characteristics, once the
components could not be changed significantly due to project timing
objectives.
This article shows a brief overview of the bolt types involved,
contextualizes the case evidencing the boundary conditions and
restrictions to achieve the technical solution and exposes the
calculation methodology for a bolted joint. The solution is defined
by calculation, experimental bench and vehicle tests for its
validation. The results conduct to the adoption of a hex flanged
serrated bolt an optimal solution for the situation.
