摘要
目的:构建救护车乘卧振动舒适性试验、分析与评价方法。方法:通过相关国际、国家标准对比分析与具体试验实践相结合,研究影响救护车乘卧振动舒适性试验的主要因素,通过测取臀、头部振动加速度进行等效加速度均方根值计算分析,可对救护车乘卧振动舒适性进行评价。结果:进一步明确了救护车乘卧振动舒适性试验条件、部位-频率二次计权分析与评价方法。结论:有助于在救护车乘卧振动舒适性试验、分析与评价方法等方面提供相关具体依据。
Objective To present the method of theexperiments,analyses and evaluations about ambulance ride comfort.Methods The comparative analyses of the relevant national and international standards were combined with experiments,and the influence factors for ambulance ride comfort experiments were explored.Ambulance ride comfort was evaluated by the weighted root-mean-square acceleration acquisition at the buttock and head.Results It further cleared the experiment conditions,the evaluations methods of position-weighted and frequency-weighted acceleration at the buttock and head.Conclusion The studies help to provide the basis for the experiments,analyses and evaluations about ambulance ride comfort.
