中文摘要:
      设计并制作一种提供正弦位移振荡且频率可调、振幅无级可调的新型振荡发生装置,阐述其结构设计及原理. 运用数学分析方法计算振荡发生装置振幅位移随时间的变化,发现振幅随时间的变化并非严格的正弦,其上半周期与标准正弦图形重合度较好,下半周期位移与标准正弦有偏差. 同时,采用实验方法验证振荡发生装置在运行过程中实际振幅随时间的变化,发现与理论计算值有一定偏差,但仍呈正弦位移运动趋势,且振幅值精度较高.
英文摘要:
      A novel type of oscillation generator was designed to create the sine displacement with continuously controllable frequency and amplitude. The structure and the principles of the device were described in detail. A theoretical mathematical model based on the geometric analysis was built to describe the variation of the amplitude over time. The analysis result shows that the variation of amplitude with time was not in strict accordance with a standard sinusoidal curve. Good agreement with the sine curve was observed at the first half period while a slightly deviation was found at the second half. Experimental measurements were carried out to validate the model and we found that there was a small deviation between the mathematical model and the actual movement. Overall,the new oscillation generator could provide the desired sinusoidal motion with precise amplitude.
