             New methods of transonic experiment in the ballistic range are presented in this paper. Two special launching techniques are used on a two-stage light gas gun, namely the filling gas techniques which can be used to obtain a projectile velocity in the subsonic range and the low filling condition technique which can be Used to reach transonic and supersonic ranges. Since initial acceleration of model is lower in the subsonie and transonic cases, models can be launched with stable attitude and undamaged ...
                本文介绍用弹道靶作跨音速试验的新方法,在二级轻气炮上采用了二个特殊的新技术:充气放炮能发射模型达到亚音速,低充填条件能发射模型达到跨、超音速。由于初始加速度较小,发射的模型外形完整,姿态稳定;加上没有支撑干扰和小洞壁效应的优点,使弹道靶设备在跨音速实验方面有特殊的优越性,用上述技术得到了圆球跨音速流场的清晰照片,其中击波脱体距离、分离点位置、颈部宽度、尾迹形状与超音速、高超音速流动比较有明显变化。文中M≈1.010和M≈0.99的二张全流场照片是十分有意义的。最后提出一个想法,用靶场加压、降温的方法可以提高雷诺数直到10~7以上。

                文章给出了玻璃纤维材料隔振系统,在几种厚度和荷重情况下,高频绝对传递率的测量结果。结果表明,这种材料隔振系统在各频率的输入加速度相等条件下,其高频传递率比普通简单系统的相应值要高。发现用弹簧刚度随频率平方增加的线性变刚度系统,能在一定频率范围内,较好地模拟玻璃纤维材料隔振系统的高频传递特性。理论计算曲线与实测值符合得很好。文章还给出了用传递率测量值确定变刚度系统参数的近似方法,估算了该方法的误差,其粗度足以满足工程要求。对于变刚度系统振动方程的求解,根据输入荷载的类型,可以化为不同情况的简单系统的振动方程来求解。
