N2 - In this work, the procedure for experimental validation of a pericyclic transmission is described. From its conception in 1970's, the nutating (now pericyclic) mechanical transmission has undergone several years of rigorous analysis in hopes of addressing common drivetrain considerations of noise, maintenance, and power density. These analytical studies have led to the fabrication of a 50 HP 32:1 reduction ratio prototype, meant to demonstrate whether it can achieve the theoretical design goals. The final analyses will be detailed characterizations of the system's torque transmission, thermal efficiency, and vibration under dynamic load. This paper outlines the successful assembly and alignment procedures, validated by contact pattern and tooth strain, as well as the experimental layout for the dynamic testing of a pericyclic transmission.
