Problems solved by technology

However, the measurement of the gravitational acceleration in the prior art is only fixed on the motor for experimentation. Whether the motion state of the pendulum ball or the position of the frame is under ideal conditions is not limited, and there is still a large error in the entire measurement result.

Abstract

The invention discloses an intelligent gravitational acceleration measuring instrument based on a conical pendulum, which comprises a shell, a conical pendulum body which is mounted on the shell and can perform conical pendulum motion for measuring gravitational acceleration, a levelness adjusting device which is arranged on the shell and is used for adjusting the levelness of the shell, a monitoring device which is installed in the shell and used for monitoring the specification of the shell and the position change state of a pendulum ball in the conical pendulum body, and a measuring devicewhich is arranged on the shell and is used for measuring the height and the rotation period of the pendulum ball and calculating the gravitational acceleration. The motion state of the pendulum ball and the position of the rack can be measured and monitored, and what is ensured is that the experimental environment of the rack and the pendulum ball is in the most ideal state.

Description

technical field [0001] The invention relates to the technical field of precise measurement, in particular to an intelligent gravitational acceleration measuring instrument based on a conical pendulum. Background technique [0002] There are many methods for measuring the acceleration of gravity. For example, the experiment of a single pendulum meets the experimental principle when the small swing angle is small (the swing amplitude is less than 5 degrees). Small, it is easy to be interfered by other factors (such as wind speed, friction, etc.); the error of the falling ball method mainly comes from the width of the light shield, timing system and human operation, etc., and it is difficult to avoid; The line is difficult to meet the requirement of equal length, it is difficult to release the pendulum ball manually to ensure the stability of the pendulum ball swing trajectory, and the air damping has a great influence on the shape of the system and the rate of torsional vibrat...
