摘    要:针对采用冲击摆测量微小冲量实验中角编码器输出波形的特点,将冲击摆系统中的摆杆看成是Bernoulli-Euler梁,从而通过对Bernoulli-Euler梁在冲击载荷作用下的横向振动分析,合理解释了角编码器输出信号的失真现象;分析了实验过程中振动的影响因素,提出了减小振动的相应改进措施;通过实验验证了改进措施的可行性.同时,该振动过程分析将为处理冲击摆中角编码器失真信号,提供一定的依据.

关 键 词:冲击摆 冲量测量 振动分析 Bernoulli-Euler梁

Abstract:Based on the characteristics of the output wave shape in the impulsemeasurement experimentation by using pendulum apparatus, the pole of the pendulum apparatus is regarded as the Bernoulli Euler beam. The paper explains the distortion phenomena of the output signal of the angle coder by the way of analyzing the transverse vibration of the Bernoulli Euler beam under impact loading, studies the factors which influence the vibration, and puts forward the improved measurement of reducing vibration. Through the experimentation the paper proves the feasibility of the measurement. Furthermore, the analysis of the vibration provides an basis for dealing with the distortion signal of the angle coder of the pendulum apparatus.
Keywords:impact pendulum   impulse measurement   vibration analyzing   Bernoulli-Euler beam
