摘要
Abstract
Coriolis acceleration is generally recognized as the key and difficult teaching point in theoretical mechanics .How to figuratively display Coriolis acceleration is always the goal that scholars and college teachers are pursuing .For this problem ,a perfect combination of rotation and linear motion for the ball can be achieved skillfully at the globe in line with the shape of the globe .Accordance to the theory of Coriolis acceleration ,a linear motion device with different speed settings can be set up on a platform , which is rotary with adjustable speeds .The ball moves in straight line on the rotary platform ,which is affected by Coriolis force .At the initial state ,the steel ball installed within the movement device is in e-quilibrium .Then at the working stage ,the spring becomes deformed under the compression by the steel ball because of Coriolis force .The transmission mechanism composed of a pulley ,a wire and a displace-ment compensation wire rod transmits the amount of spring deformation to a display device ,which re-veals the presence and the magnitude of Coriolis acceleration .Different from the existing Coriolis accel-eration test devices ,the proposed device has a novel structure ,which can attract students to understand deeply and grasp the concept of Coriolis acceleration .关键词
