velocity graph meaning in Chinese

速度曲线

Input pulse signal can be directly transformed into micro - step linear motion by use of linear pulse motor , which have found wide applications in the digital linear servo systems with high positional accuracy and high reliability . taking slpmu - 025a , a two - phase hybrid lpm manufacturing by shinko motor company ltd , as an specimen , the study on the drive control system is carried out in this thesis , which contains : ( l ) three kinds of drive circuits are designed and comparison analysis in theory is done ; ( 2 ) introduction to at89c51 microchip as controller and special micro - step constant current driver , a great variety of running modes driver control are developed ; ( 3 ) experimental testing and theoretical analysis of current waveforms and displacement graphs and velocity graphs are carried out in case of different micro - step constant current driver
本文以日本神钢电机株式会社生产的两相混合式直线脉冲电机slpmu - 025a为样机，对直线脉冲电机的驱动控制系统进行了研究，内容包括： ( 1 )设计了几种直线脉冲电机驱动器电路，从理论上进行了对比分析研究； ( 2 )用at89c51单片机作为控制器，采用专用的恒流细分驱动器sh ? 2h057m ，实现了开环控制方式下对slpmu ? 025a样机各种运行方式的驱动控制； ( 3 )对不同细分数下恒流驱动的电流波形以及各种运行方式下的位移图、速度图进行了实验测试和理论分析研究。
