| 摘 要： | 目的对某型特种车辆行车状态下驾乘人员座椅部位振动进行测试,分析座椅部位的振动特点,提出相应的振动防护措施。方法选用某型特种车辆A、B进行陆地行驶试验,对驾乘人员座椅部位振动加速度进行测试,分析相应的"疲劳-降低工效界限"的允许暴露时间Tfd的变化规律。结果/结论被测座椅部位振动对应的Tfd呈现明显的方向性差异,驾驶员座椅部位振动环境最为恶劣,需重点提高对驾驶员座椅部位前后方向振动的防护水平。

| Abstract: | Objective:to test drivers and passengers’ seat surface vibration in the process of driving,analyze the vibration characteristics and propose vibration protection measures.Methods: to measure vibration acceleration of seat position by having road test for special vehicle A and B,test and analyze the vibration acceleration of drivers and passengers ’seat surface,and analyze the change law for corresponding exposure time of fatigue-ergonomics lower limits(Tfd).Results/Conclusions: the Tfd of corresponding seat surface presented obvious directional differences,vibration environment of the driver seat was worse,so the key should be improving vibration protection level of the driver seat. |
