Calculation of angular velocity, angular acceleration and torque of two common point rigid bodies using IMU

Abstract

The aim of this study is to calculate the angular velocity, angular acceleration, and torque of two rigid bodies that share a common point using instantaneous sensor measurements. The goal of this approach is to produce outcome measurements free from accumulated error. IMU sensors and accelerometers have been used to capture real-time data. This arrangement is applicable to cases such as when the bodies are connected by a ball-and-socket joint, a Hooke joint, or a revolute joint especially where it is impractical to use a joint measurement sensor between the bodies such as measuring the relative motion of human limbs. The proposed system has been designed, built and tested in lab which showed satisfactory results.

Theoretical Research on the Flight of Onion Seeds under Discharge from the Seeding Unit

“…where V a -seeder speed, m/s; R -radius of the support wheel, m It is known that the angular velocity of a link is the same at all points of the link. [9,10]. Therefore, we will take the angular velocity of the drive sprockets equal to the angular velocity of the support wheel.…”

Transmitted Torque Analysis of Coaxial Magnetic Gears with Different Pole-Pair Numbers

“…As already known, the torque density varies depending on magnetic gear design, an optimum design for SPM type magnetic gear. Research [9,10,11] shows how to optimize the transmitted torque. As long as the torque density can be optimized, the next step will be ensuring the ef iciency of power transmission, an experimental test report of ef iciency improvement [12], and the high-ef iciency in-wheel magnetic gear [13] shows the highly potentiated magnetic with the maximum ef iciency at around 94.4%.…”
