<p>Ambulance not only plays the role of transporting patients, but also provides a comfortable environment for patients. However, bumpy roads increase human vibration and reduce the comfort of patients.

摘要

Ambulance not only plays the role of transporting patients, but also provides a comfortable environment for patients. However, bumpy roads increase human vibration and reduce the comfort of patients. Therefore, it is necessary to analyze the vibration of human body and put forward the measures to reduce the vibration. Firstly, the vibration test of human body is carried out, the acceleration and comfort of human body are analyzed, and the corresponding relationship between subjective data and objective data is established, so as to determine the control target of acceleration of different parts of human body. The test results show that the vibration of different parts of the human body is different, and the back and shoulder are the most sensitive to vibration, and most of the symptoms are dizziness and palpitation. In order to reduce the vibration of the back and shoulder, the saddle-shaped back pillow (SBP) and C-shaped auxiliary head pillow (CSH) with variable stiffness are designed. The ideal damping effect of SBP and CSH is verified by the coupling dynamic simulation model of human–vehicle–road. The comparative test results show that SBP and CSH can reduce human vibration by up to 20%, which can help enhance patients’ comfort.
