The concepts of structural dynamics are incorporated into the following 4 challenges. Each chapter includes one challenge, showcasing a different concept exemplified with 3D printed designs. In the first chapter the goal was to design a 3D printed wheel that had the lowest possible acceleration when 4 nuts were press fit into it. The design had restraints requiring creative solutions to solve problems. Challenge 2 was all about designing a reciprocating motion mechanism to drive a table. The target for this was originally to archive 15g but due to constraints of materials this was modified. In Challenge 3 the task was to design 4 columns for a provided 3D printed structure. The goal was to create structure with a natural frequency of 4.5 Hz. The last challenge was all about seeing how the structure created in Challenge 3 reacted when a driving frequency was applied to it by the table created in Challenge 2.

This report evaluates the dynamic response of structures using designed 3D-printed components. It is divided into four challenges, where each addresses different aspects of structural dynamics. Challenge 1 involves designing a wheel that can achieve a low angular acceleration, while exploring the principles of rotational motion. In Challenge 2, a shake table is created using a reciprocating motion system machine to convert rotational motion into linear or ground motion beneath a structure. Challenge 3 includes various free vibration tests conducted at a targeted natural frequency, achieved through the design of structural columns. Finally, Challenge 4 builds upon what was done in Challenges 2 and 3, by testing the structure’s displacement and transmissibility when subjected to forced vibrations generated by the shake table in Challenge 2.
