This post will detail an experiment in which the wave sensor was attached to a rotating arm at three different diameters. These diameters were 40cm, 60cm and 80cm. For each diameter, measurements were taken at two speeds to get an … Continue reading →

Post #5 outlined the steps used to go from vertical acceleration to vertical displacement and how the results were completely off. The reason why each of the displacement graphs at the end of the post look so totally different just … Continue reading →

This post will examine the steps currently being used to go from vertical acceleration data to vertical displacement and the issues involved. Step 1: Getting acceleration data The first step is to setup the rotating arm with the IMU attached, … Continue reading →

Some observations on vertical displacement: Getting displacement data from an acceleration signal is possible by double integration. This double integration causes issues as any error present in the original acceleration signal will accumulate at an exponential rate in the displacement … Continue reading →
