A Pre-Experimental Framework for the Investigation of Phase-Controlled Multi-Mass Systems

This work presents a pre-experimental framework for the investigation of phase-controlled, mechanically coupled multi-mass systems under external energy input. The focus lies on the detection of potential systematic deviations in the measured normal force that cannot be fully attributed to known coupling or artifact effects. A minimal dynamic model is introduced together with a corresponding measurement formulation. The framework includes an experimental architecture designed for reproducibility and systematic artifact separation, as well as a statistical decision structure based on null hypothesis testing (α = 0.05). The approach explicitly avoids any assumptions regarding new physical principles. The scope is limited to system dynamics, measurement methodology, and controlled experimental evaluation. The objective is to establish a structured and reproducible basis for future experimental investigations of complex internally coupled dynamical systems.
