某型急救车舱内噪声分析与优化OACSTPCD
Analysis and optimization of cabin noise for one ambulance
目的:分析某型急救车舱内的噪声并进行优化,以降低车舱内噪声,提高作业的舒适性.方法:在典型工况下,选取车舱内医护人员、卧姿伤员和坐姿伤员耳畔作为测试点,对某型急救车舱内的噪声进行测试,通过对噪声分布和频谱进行分析,进一步确定噪声源的位置、频率和传递方式,并针对性地通过优化排气管结构布局降低排气噪声、增加前后轮罩气密性降低轮胎噪声、优化和加强悬置设计降低机械传动噪声,降低整车的振源激励和振动传递.结果:通过性能优化,急救车舱内全部测试点的噪声均符合…查看全部>>
Objective To analyze and optimize the noise in the cabin of some type of ambulance to enhance comfort during operation.Methods The cabin noise of some ambulance was tested under typical working conditions with the test points near the ears of the medical personnel and litter and ambulatory casualties so as to analyze noise distribution and spectrum,and the location,frequency and transmission mode of the noise source were determined,then some measures were ta…查看全部>>
