一、前言从开始出现气动工具以来,至今还没有完全解决气动工具振动公害的难题。在漫长的岁月里,不知有多少工人因使用气动工具而患振动病,他们不仅长期经受振动病的痛苦折磨,而且有的甚至被夺去生命。随着生产机械化的不断发展,由于广泛使用气动工具,从事气动工具作业的人员日益增多,尤其大量使用高转速、高冲击频率、大冲击能和大功率的气动工具,因此,气动工具的生产性振动对人体的危害就显得突出,振动病已成为常见的职业病了。气动工具振动测试技术是振动危害防治和减振技术研究的基础。没有准确的测量,就不可能正确评价气动工具和确定其振动级,更不可能向气动工具设计师提出合理的
I. INTRODUCTION Since the beginning of the emergence of pneumatic tools, the problem of vibration of pneumatic tools has not been completely resolved. During the long years, I do not know how many workers suffered from vibratory diseases due to the use of pneumatic tools. They have not only suffered long-term pain from vibration but have even been taken away. With the continuous development of production mechanization, due to the extensive use of pneumatic tools, the number of personnel engaged in the operation of pneumatic tools is increasing, especially the use of high-speed, high-impact frequency, large impact energy and high-power pneumatic tools, so the productivity of pneumatic tools The harm of vibration to the human body becomes apparent, and the vibration disease has become a common occupational disease. Pneumatic tool vibration test technology is the foundation of research on vibration hazard prevention and vibration reduction technology. Without accurate measurements, it is not possible to properly evaluate the pneumatic tools and determine their vibration levels, and it is even less likely to propose reasonable solutions to the pneumatic tool designers.
