Vibration

Validation of a ride comfort simulation strategy on an electric Stewart Platform for real road driving applications

“…This has been obtained by trigonometry, taking into account the seat θ y ss inclination angle (see section Seat sensor).As can be seen in Figure9, there is a good match between the signals measured in the Prius seat (blue lines) and the signals measured in the platform seat (orange lines) under the same driving maneuvers. From here, it can be deduced that the accelerations in the z-axis show the smallest deviations, which benefits the study since this axis is the one that has the greatest influence on comfort in passenger cars 7. The x-axis (the second axis with the greatest influence on comfort) shows larger deviations, but with maximum errors at low speeds.…”

“…From here, it can be deduced that the accelerations in the z -axis show the smallest deviations, which benefits the study since this axis is the one that has the greatest influence on comfort in passenger cars. 7 The x -axis (the second axis with the greatest influence on comfort) shows larger deviations, but with maximum errors at low speeds. Finally, the y -axis has maximum deviations in the high frequency range (appreciated in the bump roll left test), which may be due to the influence of the stiffness of the simulator screens on the dynamic behavior of the platform even after having applied the control strategy.…”

“…8 Vibrations beyond 10 Hz have local effects. Then, this study will focus on the most problematic frequency range of WBV (1)(2)(3)(4)(5)(6)(7)(8)(9)(10).…”

“…6 In this sense, most problematic frequencies in terms of sensitivity to WBV are between 1 and 10 Hz. Vibrations up to 10 Hz affect all of the human organs, being the human body most sensitive to vertical vibrations in the 4–8 Hz frequency range, 7 and 1–2 Hz in the x and y directions. 8 Vibrations beyond 10 Hz have local effects.…”

Alterações cognitivas, funcionalidade e qualidade de vida de pacientes portadores de Diabetes Mellitus em uma unidade básica de saúde

“…Com os avanços tecnológicos criou-se a expectativa de controle através de tratamentos eficientes (5) , com total remissão dos sintomas. A evolução crônica e silenciosa da DM pode ter como consequência a longo prazo senão tratada adequadamente, incluindo complicações e graves problemas de saúde (6,7) , em conjunto do impacto de comorbidades psiquiátricas.…”
