在本发明的描述中,需要说明的是,术语“中心”、“上”、“下”、“内”、“外”等指示的方位或位置关系为基于附图所示的方位或位置关系,仅是为了便于描述本发明和简化描述,而不是指示或暗示所指的装置或元件必须具有特定的方位、以特定的方位构造和操作,因此不能理解为对本发明的限制。术语“第一”、“第二”仅用于描述目的,而不能理解为指示或暗示相对重要性。此外,在本发明的描述中,除非另有说明,“多个”的含义是两个或两个以上。
如图1所示的本发明的结构简图中,本发明主要包括底座1以及夹具,所述底座为L型铝合金网孔板,在底座上安装一组固定式夹具和一组可调式夹具,且固定式夹具;在底座的纵向段表面安装滑轨2,在滑轨上滑动安装滑块,在所述滑块上固定安装电子拉力计3和位移传感器4,电子拉力计一端设有挂钩6,挂钩与固定式夹具上的被测物之间通过拉线连接;在滑轨与夹具之间安装恒定液压推力器5,所述恒定液压推力器的推杆与滑块贴合并推动滑块移动。
所述固定式夹具7由两个固定座和一个夹头A组成,夹头A前部为夹口、尾部为安装杆,安装杆穿过两个固定座与其进行连接,固定座安装在钢板的横向段表面。
所述可调式夹具8由一根立杆和一个夹头组成B,夹头B前端为夹口、尾端为带有穿孔的连接杆,连接杆套接在立杆上并用紧固螺栓进行固定。
本发明的工作过程大致如下:
操作者将兔子的股骨夹持在可调式夹具的夹口处,将胫骨夹持在固定式夹具的夹口处,将电子拉力计的拉力挂钩通过拉线与兔子胫骨相连,然后控制恒定液压推力器工作,利用恒定液压推力器缓慢匀速的推动滑块移动,在滑块移动的过程中,电子拉力计和位移传感器开始工作,记录拉力变化值以及位移变化值,直到胫骨断裂,此时记录下电子拉力计的数值和位移值,便可完成实验测试。
