摘要

手动轮椅(MWC)使用者在推进过程中每天都暴露在振动中。这种接触对MWC使用者健康的影响尚未得到证实。到目前为止,还没有达成一致意见,大概是因为需要控制的实验参数种类繁多。一种可能的解决方案依赖于用户/MWC模型的实现,以指出推进条件(MWC负载、推进方法、速度和底层类型)对振动暴露的影响,并最终对MWC用户的健康产生影响。为了建立这样的模型,需要对MWC在推进过程中的振动响应进行评估。在实验室条件下进行必要的MWC实验模态分析后,本研究给出了MWC在不同推进条件下的振动响应。针对每一种工况,给出了识别出的模态参数集,并强调了用户/MWC界面处对MWC振动响应的影响。结果主要强调了对振动的响应高度依赖于推进条件。速度和地面类型对振动响应影响较大:速度加倍和地面粗糙度增加分别意味着振动级别增加3倍和8倍。最后,主要结果是空的MWC或装载假人的MWC产生的振动超出了装载人体的MWC的测量范围,导致频率含量较低,振动水平几乎增加了两倍。这项研究的结果将有助于提高对轮椅使用者因振动而面临的健康风险的理解。

Vibration Response of Manual Wheelchairs According to Loads, Propulsion Methods, Speeds, and Ground Floor Types
Manual wheelchair (MWC) users are daily exposed to vibration during propulsion. The impact of such exposure on the MWC user’s health has yet to be proven. To date, no agreement has been reached, presumably on the account of the wide variety of experimental parameters that need to be controlled. A possible solution relies on the implementation of a User/MWC model to point out the effect of propelling conditions (MWC loads, propulsion methods, speeds, and ground floor types) on the vibration exposure and eventually on the MWC user’s health. To feed such a model, the evaluation of the MWC vibration response during propulsion is required. Following a necessary MWC experimental modal analysis under laboratory conditions, this study presents the vibration response of an MWC under various propelling conditions. For each investigated condition, the identified set of modal parameters was provided and the effect on the MWC response to vibration at the User/MWC interfaces was highlighted. Results mostly underline that the response to vibration is highly dependent on the propelling conditions. The speed and the ground floor type greatly affect the vibration response: doubling speed and increasing ground surface roughness imply threefold and eightfold vibration levels, respectively. Finally, the main outcome is that an empty MWC or an MWC loaded with a dummy generates vibration outside the range measured for an MWC loaded with a human body, resulting in a lower frequency content and an almost two-fold vibration level increase. The findings of this study will help enhance the understanding of the health risks that wheelchair users encounter as a result of vibrations.
