针对恒天重工股份有限公司技术开发中心开发的单字头和双字头针刺机在试验过程中存在的针刺频率和针刺密度低的问题，分析了针刺机的针刺频率、针刺密度与设备偏心主轴振动和强度的关系，认为可以通过运动分析、测量及计算使针刺机的振动、强度量化，从而为提高针刺频率和针刺密度提供依据． For the lower needle frequency and needle density problems of the single word head and dual prefix acupuncture machine developed by Technology Development Center of Hengtian heavy industry, the relations between the needle frequency, needle density and the equipment vibration are analyzed, the results have shown that the acupuncture machine vibration and the intensity data can be quantified by the motion analysis measurement, by which the needle frequency and needle density of the acupuncture machine can be improved .
