Description
所属技术领域
本发明属于机电技术领域,涉及一种拉伸试验装置,特别涉及一种电活性聚合物等双轴拉伸试验装置。
背景技术
电活性聚合物(Electroactive Polymers,简称EAPs)是在电场的激励下,基于麦克斯韦效应,尺寸和形状发生显著改变的一种新型智能材料。EAPs具有能量密度高、应变大、质量轻、柔韧性好等优点,在作为驱动器方面已有很多应用研究,近十几年来,对EAPs的发电特性研究成为另一热点问题。在电活性聚合物双轴拉伸发电实验过程中,很难实现在拉伸过程中材料受力均匀且保持两个方向上拉伸距离一致,EAPs容易在拉伸过程中破裂,不利于实现EAPs材料的大变形。
发明内容
本发明的目的是提供一种适合于电活性聚合物等双轴拉伸的试验装置,利用该装置可以实现电活性聚合物材料等双轴拉伸,而且使材料在拉伸过程中受力均匀,在两个方向上变形一致,可以实现较大的变形量。
为了实现上述任务,本发明采取如下的技术解决方案:该电活性聚合物等双轴拉伸试验装置,由伺服电机、电动伺服缸、支撑后板、底板、支撑板、移动L型导轨、长账本螺钉、菱形条、账本螺钉、固定L型导轨、支撑前板组成,支撑前板、支撑板和支撑后板固定在底板上;伺服电机固定在支撑后板上;电动伺服缸安装在支撑板与支撑后板之间;移动L型导轨固定在电动伺服缸的伸缩杆上,固定L型导轨固定在支撑前板上;菱形条两端用账本螺钉连接,中心用长账本螺钉连接,且长账本螺钉连接到L型导轨的导槽中;电活性聚合物薄膜粘贴在菱形条内侧的顶点上。
特色与优势:该装置可以把电活性聚合物材料进行等双轴拉伸,结构简单、变形均匀,可实现在两个方向上同时、等距拉伸,使电活性聚合物在变形过程中更稳定,受拉伸而不易破裂,提高其使用寿命,大大增强了电活性聚合物的变形能力和发电性能。
附图说明
图1为本发明电活性聚合物等双轴拉伸试验装置的整体结构示意图;
图2为本发明图1中的局部放大图;
以下结合附图对本发明作进一步的详细说明。
具体实施方式
参见图1~2,本发明的电活性聚合物单双轴拉伸试验装置,包括伺服电机(1)、电动伺服缸(2)、支撑后板(3)、底板(4)、支撑板(5)、移动L型导轨(6)、长账本螺钉(7)、菱形条(8)、账本螺钉(9)、固定L型导轨(10)、支撑前板(11)。
支撑前板(11)、支撑板(5)和支撑后板(3)固定在底板(4)上;伺服电机(1)固定在支撑后板(3)上;电动伺服缸(2)安装在支撑板(5)与支撑后板(3)之间;移动L型导轨(6)固定在电动伺服缸(2)的伸缩杆上,固定L型导轨(10)固定在支撑前板(11)上;菱形条(8)两端用账本螺钉(9)连接,中心用长账本螺钉(7)连接,且长账本螺钉(7)连接到L型导轨(6)(10)的导槽中。
工作时,首先将一定尺寸的方形电活性聚合物薄膜粘贴在菱形条(8)内侧的顶点上,之后启动伺服电机(1),利用伺服电机(1)的正反转控制,通过电动伺服缸(2)带动移动L型导轨(6)来回运动,从而使菱形结构变形,实现在一个驱动力的作用下就能进行电活性聚合物薄膜在两个方向上的同步等双轴拉伸。通过对电活性聚合物薄膜的拉伸与收缩,可实现机械能与电能的转换。
