乘用车室内噪声与乘员心率和舒适性模糊评价关系研究

乘用车室内噪声是影响汽车乘坐舒适性的重要因素之一。从乘用车室内噪声模拟试验入手,通过客观生理指标的变化来评价汽车乘坐舒适性,实现对主观评价的客观化,尝试提出一种乘员烦躁度的客观—主观模糊评价方法。结果表明,心率变异性分析中的LF、HF及LF/HF指标可在一定程度上反应车内乘客的噪声舒适度。随着噪声舒适度等级的降低,相应的HRV生理指标LFnorm均值,LF/HF均值大致递增,HFnorm均值大致递减,并且呈现一定的线性规律。

Research on the Fuzzy Evaluation Relationship of Passenger Car Interior Noise Members'Heart Rate and Ride Comfort

The interior noise of a passenger car is one of the important factors affecting the ride comfort of a car.Starting from the passenger car interior noise simulation test,the ride comfort of the car is evaluated through the changes of objective physiological indicators,and the subjective evaluation is objectified.An objective-subjective fuzzy evaluation method of occupant irritability is proposed.The results show that the LF,HF and LF/HF indicators from the heart rate variability analysis can reflect the noise comfort of passengers in the car to a certain extent.As the noise comfort level decreases,the corresponding HRV physiological index LFnorm average,LF/HF average increases roughly,and the HFnorm average decreases roughly,showing a certain linear law.
