摘　　要：静重式力标准机是力仪测试中应用最普遍、准确度等级最高的力标准机,它是以砝码串的重力作为标准力值。针对力标准机工作过程中砝码串的摆动现象,分析了现象产生的原因,提出了摆动角的测量和计算方法,并对砝码串的摆动过程进行分析和计算,得出了砝码串摆动对标准力值影响量的大小。将得出的摆动影响量与标准力值的允许误差进行对比分析,给出了较为合适的判断依据。The static weight type force standard machine is the most widely used in the force meter test, the highest accuracy of the force standard machine, it is the weight of the string as the standard force value. Farmer oscillation phenomenon of the working process of force standard machine series, this paper analyzes the causes of the phenomenon, put forward the measurement and calculation method of swing angle, and the weights on the swing process analysis and calculation, the weight on the size of the swing value affect the amount of standard force. The comparative analysis of the allowable error between the swing effect and the standard force value is given.
