介绍一种校准加速度计的新装置

A new apparatus for calibrating the accelerometer

混合摆是由单摆与复摆构成的新型摆。它克服了单摆与复摆的缺点,兼有二者的优点。介绍了这种摆的结构原理、性能特点和没计依据,阐明了其冲击加速度的计算与测试方法。这种装置避免了地球重力加速度的影响,适合于中低档g值加速度计的校准工作,其准确度优于5％。

The mixed pendulum is a new one which consists of a simple pendulum and a compound pendulum. It overcomes the shortcomings of simple and compound pendulums themselves, and has the merits of them respectively. its construction, principle, performance and design basis are described and the calculation and measurement methods of shock acceleration for the mixed pendulum are explained. This apparatus can avoid the influence of gravitational acceleration, and it is suited for calibrating accelerometers in the range from lower to middle acceleration values. It's accuracy is better than 5％.
