Analysis and research on acceleration measurement methods for indoor large length standard devices

The indoor long length standard device is an important large-size measuring standard device, which has an acceleration and deceleration process during the starting and stopping stages of the slide. Studying the acceleration of the indoor long length standard device is of great physical significance for understanding its operating rules. In the article, a laser tracker was used to study the acceleration of indoor large length standards. Through data analysis using a laser tracker at equal sampling frequencies of 50Hz and 100Hz, some conclusions were drawn as follows: the acceleration value significantly increases when the measurement frequency of the laser tracker is increased. The maximum acceleration at 50Hz is 579.75 mm/s², and the maximum acceleration at 100Hz is 920 mm/s². After the acceleration phase is completed, the sliding table enters a constant speed phase, and the data oscillates in a zigzag pattern with zero values. After the deceleration phase is completed, the acceleration value of the sliding table steadily approaches zero.
