Strain In a Rotating Shaft Engineering 300 Open- Ended Project Strain of a Rotating Shaft Joachim Pedersen & Michael Johnson – Spring 2008
How is Data Collected From a Rotating Sensor Array? Slip Rings! And Carbon brushes!
Strength of PMMA
PMMA Tensile Performance Elastic Modulus: 313.98GPa and 280.31GPa
Maximizing Sensitivity Strain Gauges in full bridge configuration for ultimate sensitivity, 4 x that of a quarter bridge!
Data Acquisition System Ability to collect large amount of data in a short time interval. 500 samples per second. 500Hz sample rate
PMMA Rod in Action:
Initial Results
Initial Results
Standard Deviation of Data
Trends from the Data Strain In a Rotating Shaft Increases with increasing rotational speed Increases dramatically when weight is added Deflection increases with increased surface strain
Take it slow!
