摘　　要：动态力测量的场景越来越广泛,对测量准确度的要求也越来越高。为解决国内始终没有基于绝对法加速度测量的脉冲式动态力标准装置的问题,研究建立了覆盖1~200 kN范围的脉冲力激励装置。经试验证明,该装置具有较好的横向运动比和台面幅值不均匀度,具有重要技术推广价值,为促进动态力传感器在工程实践中的应用以及动态力测量技术的发展提供了有力支撑。The scene of dynamic force measurement is more and more extensive,and the requirement for measurement accuracy is higher and higher.In order to solve the problem that there is no pulse type dynamic force standard device based on absolute acceleration measurement in China,a pulse force excitation device covering the range of 1~200 kN is established.The experimental results show that the device has good lateral motion ratio and unevenness of table amplitude,and has important technical promotion value.It provides strong support for promoting the application of dynamic force sensor in engineering practice and the development of dynamic force measurement technology.
