油锯振动对人体影响的研究

The Effects of Chain Saw vibration on the Human Body

本文使用双通道信号分析仪(BK2032)和人体响应仪(2512)对YG-5型油锯系统频响函数,振动幅值,功率密度谱和人体响应振动值进行了测试,.分析了振动峰值所在的频率范围及所占振动总能量的比例,提出了保护油锯手的手臂不受损害的每班持握工作时间和油锯的防振设计如何与人体的各种要求相适应的技术依据。

Chain Saw vibration its effect on the human body with respect to frequeney, magnitude and duration per working day was analysed. The Dual Channel Signal Analyzer (BK 2032) and the Human-response Vibra- tion Meter ( BK 2512) were used to measure vibrating amplitude, power spectrum density, frequency range of vibrating peak value and the percentage in all vibration energy. The purpose of this research is to help determine daily exposure time to chain saw vibration, improving occupational safety standards.
