At the lowest frequency, the maximum angular accelerations of the platform were thus well below the vestibular canal's perception threshold, namely 0.2°/s2 [33].
The mean maximum resultant angular accelerations for the concussion and no-injury cases were 7951 rad/s (SD 3562 rad/s) and 4300 rad/s (SD 3657 rad/s), respectively.
The mean maximum resultant angular accelerations for the concussion and no-injury cases in the current study were 7951 SD 35622 rad/s) and 4300 rad/s (SD 3657 rad/s), respectively (figure 2).
Maximum ω and leg angular acceleration are probably constrained by mechanical or energetic limits (Doke et al. 2005).
Simulation results confirm that multi-objective control with wheelbase preview achieves a significant improvement of ride quality (a maximum 27percent and 600 percent improvement on vertical and angular acceleration, respectively) comparing with that of control without preview, while suspension deflections, tyre deflections and actuator forces remaining within given bounds.
The absence of a handle increased angular acceleration, impact velocity, impulse, and maximum force, and ultimately increased impact stress by 25%.
For example, Wang, Vrongistinos, & Xu [ 34] found that over consecutive pushes during wheelchair sprinting, higher range of motion values occurred around the shoulder and elbow leading to greater maximum angular velocity of the upper arm and forearm and an increased range of motion over which angular acceleration could be produced.
And then we have the acceleration due to gravity, reflected through the angular acceleration times the sine of the angle, the angular acceleration due to the external disturbances, and finally, the angular acceleration due to the motion of the cart.
Normalized root-mean-square errors for impact time traces were 9.9±4.4%4% for linear acceleration, 9.7 ± 7.0% for angular acceleration, and 10.4 ± 9.9% for angular velocity.
