Résumé:
In this work, we propose to study the installation of aluminum rivets, applying force to
the rivet to assemble parts, this operation will be carried out by a robot (Staubli TX90) with
four rotoid joints, the robot is equipped with a pneumatic hammer that will generate a series of
shocks to deform the cylindrical head of the rivet. The latter will take on a permanent domed
shape. This operation will excite the structure which will in turn be susceptible to vibrations.
To carry out this work, we blocked the joint 4 and 6, and we modeled the structure using
SolidWorks in different configurations to calculate the natural frequencies in order to avoid the
resonance of the robot structure, then, we studied the inverse dynamics of the robot to verify its
operation under the effect of the weight of the tool which is the pneumatic hammer.
