介绍一种校准加速度计的新装置

A NEW UNIT FOR THE CALIBRATION OF ACCELEROMETERS

混合摆是由单摆与复摆构成的一种新型摆。它克服了单摆与复摆各自的缺点，兼有二者的优点。本文介绍了这种摆的结构原理、性能特点和设计依据，而且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 overcomed theshortcomings of simple and compound pendulums themselves,and has the merits of them respectively. This paper described its construction,principle, performance and design foundation,and explaind the calculation and measurement methods of shock acceleration for the mixed pendulum. This unit avoided the influence of gravitational acceleration. The unit is suitable for calibrating accelerometers in the range from lower to middle acceleration values. Iiis accuracy is better than 5 %.
