概要
目的:由于现有的电动液压泵的驱动性能(压力和流量)有限,所以本文期望通过采用数字制造和堆叠的方式来提高电动液压泵的输出压力和流量。 创新点:1. 通过数字制造的方式实现可弯可扭的电动液压泵;2. 采用设计和加工后的电动液压泵来驱动偏心执行器。 方法:1. 采用实验的方式测量堆叠式电动液压泵的输出压力和流量,并与单层式电动液压泵的输出压力和流量进行对比;2. 通过驱动柔性偏心执行器的方式,评估其响应特性,并用弯曲角度大小来衡量泵源的性能。 结论:1. 设计、制造和表征了单层式和堆叠式电动液压泵。2. 通过性能比较可知,堆叠式电动液压泵的输出压力和流速分别为15.8 kPa和37.02 mL/min,而单层式电动液压泵的输出压力和流速分别为3.2 kPa和24.09 mL/min。3. 堆叠式电动液压泵驱动的偏心执行器可在8 s内实现240°的偏转角度,并在3 s内快速返回到原始位置。
