Predicting Peak Displacement in Imbalanced Rotating Drum

In summary, the conversation discusses ways to prevent a suspended motor-rotating imbalanced drum of high mass from colliding with its enclosure in a washing machine. The participants suggest using a single sensor to accurately measure acceleration and rate of rotational change in XYZ planes to predict the maximum displacement from a balanced center of rotation. They also discuss the possibility of improving the machine's design and control algorithm to better handle vibrations and prevent collisions. Some suggestions include using limit switches, accelerometers, or a combination of both, as well as using a MEMS accelerometer to detect excessive vibration. The conversation also touches on the challenges of implementing a new algorithm and the use of other sensors such as microphones and tachometers to detect vibrations.
