Sensor results from pendulum swing and outlooks for cricket bat swing parameterizations


Ajay K Sarkar

The use of sensors is now achieving rigorous attention in cricket research. Attaching a triaxial accelerometer sensor to a rigid wooden pendulum, the tilted and deflection angles during its stationary and swing position was investigated. The tilted angles at different static steps and swing angles were measured using the sensor output and compared with inclinometer readings (static case) and with those estimated using the solution of a damped pendulum equation (swing case) and a good agreement were obtained (r = 0.99, p<0.0001 and r = 0.88, p<0.0001 respectively). The wooden pendulum was not frictionless, a correction was attempted by choosing varying damping constant for the equation and improved matching obtained (r = 0.91) with the improved slope of the regression line. The bias error was also attempted to minimize. This study foresights that the damping constant could be a criterion to measure swing inertia related parameters in cricket batting research.
