If I am attempting to prevent a suspended motor-rotating imbalanced drum of high mass from colliding with its enclosure, how can I attempt to predict the maximum displacement from a balanced center of rotation if I have only a single sensor that can accurately measure(1000 samples/sec) acceleration and rate of rotational change in XYZ planes?
What I need to know how to do is to predict when a rotating drum is on a collision course with it's enclosure.
Case in point: Washing Machine, front-loader, a rotating heavely weighted drum/motor assembly filled with a little water and a lotta clothes that is ballasted by heavy weights, encumbered from excess travel by a few incompetent shock absorbers and suspended from two large springs, but is otherwise balanced in a vertical plane when unloaded with water and wash.
Can someone help me with the calculations? I haven't studied physics except for a single course in general physics. I am not a mechanical engineer. I do understand algebra, trig, math and I understand well the qualitative dynamics of mechanical systems and even remember doing well in calculus I and II, but what I do best is programming embedded MCU's. I code.
