摘要
本文论述稳态正弦扫描激振试验方法及其在确定坦克火炮动力特性上的应用。通过实例表明,采用稳态激振方法测量传递函数,求取坦克火炮的模态参数,测量数据准确,重复性好,对研究坦克火炮行进间射击精度具有一定指导意义。
This paper discusses the stationary sinusoidal sweeping excitation method and its applications for determine the dynamic characteristics in tank gun system. It is shown by examples that using stationary excitation method to measure the transfer function and then to obtain the modal parameters of tank gun system, the measuring data is accurate, the repeatability is good and it has some guiding values for studying the accuracy of fire in moving tank.
