Description

一种滑轮组放大加速式可组装型落锤试验系统 技术领域
本发明涉及一种用于结构构件的冲击试验装置，尤其涉及一种滑轮组放大加速式可组装型落锤试验系统。
背景技术
在土木建筑工程领域和运载工具制造领域都经常涉及到冲击碰撞的试验问题。对于土木结构工程，如结构柱、墙等竖向受力构件的受冲击的力学性能和能力关乎到整个结构以及相应的人身财产安全。而对于运载工具制造领域，如汽车之间的碰撞以及汽车与道路桥梁防护机构之间的碰撞目前也是关乎社会人身财产安全的重要问题。因此，结构构件在冲击荷载作用下性能研究以及测试极为重要。
目前，在进行大型结构及构件的碰撞冲击性能试验时，通常使用的装置都是落锤冲击试验系统。其主要的工作原理是：安装锤头在落锤试验架上，试验时释放锤头，锤头沿着安装好的导轨做自由落体运动，从而使锤头获得相应的速度和动能以此冲击结构构件。而用这种试验装置和试验方式来应用于诸如汽车碰撞和竖向受力构件的侧向冲击的问题存在着以下不足之处：
(1)由于传统的落锤冲击实验装置完全依赖锤头自由落体产生的速度来冲击构件，其最终冲击速度与落锤的释放高度有关，但是落锤试验系统装置高度有限，因此无法进行速度较高的冲击试验。而对于汽车碰撞试验和竖向受力构件的侧向冲击试验通常都是速度较大的冲击试验，这是由研究的实际应用情景所决定的。如车辆冲击桥墩或高速护栏通常都是发生在高速公路上，而冲击车辆在冲击时的时速可以超过100km/h。如果按此速度使用传统落锤冲击试验装置，落锤释放高度将达到38米以上，显然难以满足。
(2)使用传统的落锤装置进行结构构件侧向冲击的做法通常是将构件横向固定在锤头正下方，这样才能够实现侧向冲击的试验目的。但是这种方式也存在这一定的问题：首先，这种冲击形式并不是完全模拟实际结构构件受侧向冲击的状态，横置的构件无法在轴向方向施加轴力，也无法对构件的两端模拟与实际贴合的边界约束条件。其次，传统落锤对结构构件冲击时，在冲击方向还存在着重力加速度，这样可能会造成冲击物的二次碰撞，而实际情况下的冲击物的重力加速度是不沿着构件方向的。
因此，在模拟汽车碰撞和结构构件侧向碰撞方面，传统的落锤冲击系统有着难以解决的缺陷和降低试验可信度的情况。此外，模拟汽车或其他交通运载工具的碰撞也采用实车通过斜坡或特殊的加速跑道加速运载工具模型进行碰撞试验。而这些实验设施往往需要较大的实验场地，或专有设备其造价及维护比较昂贵。
发明内容
本发明的目的在于针对现有技术的不足，提供一种滑轮组放大加速式可组装型落锤试验系统。
本发明的目的是通过以下技术方案来实现的：一种滑轮组放大加速式可组装型落锤试验系统，包括轨道，滑动平台，冲击物，缆绳，试验构件，传感器，底部钢梁，四柱框架，滑轮组，转向滑轮，落锤、反力支撑；其中，轨道、试验构件、四柱框架、转向滑轮、反力支撑均安装在底部钢梁上；反力支撑固定连接四柱框架；冲击物固定连接滑动平台，滑动平台滑动连接轨道；试验构件位于冲击物和四柱框架之间；传感器一端连接试验构件，另一端连接四柱框架；滑轮组由定滑轮和动滑轮组成，定滑轮安装在四柱框架顶部横梁上，落锤挂在动滑轮上；缆绳一端连接滑动平台，另一端与脱钩装置配合后，经过转向滑轮，再穿插绕在滑轮组的定滑轮和动滑轮上，最后固定连接滑轮组的最后一个定滑轮；脱钩装置位于滑动平台和试验构件之间。
进一步地，所述脱钩装置在冲击瞬间前使缆绳脱离滑动平台。
进一步地，所述滑轮组的动滑轮个数为n，缆绳脱离滑动平台时落锤下落的高度为h，此时落锤的速度为

按照滑轮组工作运动原理，得到试验速度为

进一步地，所述传感器为力传感器或位移传感器。
进一步地，所述转向滑轮有三个。
本发明的有益效果是：本发明一种滑轮组放大加速式可组装型落锤试验系统利用基本力学原理，在不需要过多的增加实验空间及利用其他推进设备的条件下，有效提高冲击物冲击速度来模拟实际碰撞冲击速度，使得模拟诸如汽车和构筑物碰撞等实验更为方便和可靠。
附图说明
图1为本发明结构示意图。
图中，轨道1，滑动平台2，冲击物3，缆绳5，试验构件4，传感器6，底部钢梁7，四柱框架8，滑轮组9，转向滑轮10，脱钩装置11，落锤12，反力支撑13。
具体实施方式
以下结合附图及实施例对本发明作进一步说明。
参照图1，本发明滑轮组放大加速式落锤冲击系统包括轨道1，滑动平台2，冲击物3，缆绳5，试验构件4，传感器6，底部钢梁7，四柱框架8，滑轮组9，转向滑轮10，落锤12，反力支撑13和底部定滑轮。
其中，反力支撑13通过焊接或螺栓连接固定在四柱框架8不受冲击的一侧，与四柱框架8组成自平衡反力系统，该系统通过螺栓安装在底部钢梁7上。所述冲击物3通过焊接或螺栓连接的形式固定于滑动平台2前部，两者共同组成冲击源；滑动平台2放置在轨道1上；轨道1通过型钢固定在底部钢梁7上，可通过改变型钢的高度调节冲击碰撞高度。试验构件4为被冲击物，底部通过型钢固定于底部钢梁7上，位于冲击物3和四柱框架8之间；传感器6为力传感器或位移传感器，一端连接试验构件4顶部，另一端连接四柱框架8，用于测定冲击碰撞时试验构件4顶部受到的冲击力或产生的位移。
滑轮组9通过螺栓安装在四柱框架8顶部横梁上；滑轮组9由多个定滑轮和动滑轮组成，滑轮组9的定滑轮固定在四柱框架8的顶部横梁上，滑轮组9的动滑轮个数为n，脱钩装置11使得缆绳5与滑动平台2脱离时落锤12下落的距离为h，此时落锤12的速度为
Figure PCTCN2020135936-appb-000003
按照滑轮组工作运动原理，滑轮组9中每增加一个动滑轮，通过缆绳5带动滑动平台2运动速度相应增加两倍，则理想的试验速度为
Figure PCTCN2020135936-appb-000004
根据试验需求的试验速度决定动滑轮的个数，并根据动滑轮的个数设置定滑轮，定滑轮的个数不少于n+1个。通过调整缆绳5与滑动平台2脱离时落锤12下落的距离为h，实现不同速度的冲击加载试验。此处需注意的是，根据滑轮组9的力学平衡原理，落锤12的重力需要大于滑动平台2与轨道1间摩擦力的2n倍，这样才能由落锤的自由落体带动滑动平台2和冲击物3运动。
缆绳5一端连接滑动平台2，另一端与脱钩装置11配合后，依次绕过固定在底部钢梁7上的三个转向滑轮10和一个用于导向的底部定滑轮，再与滑轮组9配合，配合部分穿插绕在定滑轮和动滑轮上，并与滑轮组9的最后一个定滑轮固定连接；落锤12同时挂在滑轮组9的动滑轮上。脱钩装置11安装在底部钢梁7上，位于滑动平台2和试验构件4之间；脱钩装置11与试验构件4受冲击面的距离不小于滑动平台与缆绳5连接处与冲击物3冲击面的距离。
本发明滑轮组放大加速式落锤冲击系统的工作过程为：释放落锤12使其向下落体，通过滑轮组9通过转向滑轮10带动缆绳5运动，继而拉动滑动平台2和冲击物3沿轨道1向着试验构件4冲击碰撞；冲击瞬间前脱钩装置11将缆绳5与滑动平台2脱离，以免造成缆绳系统的损坏；冲击物3在碰撞到试验构件4之后，传感器5直接测得试 验构件4顶部受到的冲击力或位移；同时，四柱框架8和反力支撑13组成的自平衡反力系统为冲击碰撞提供反力支撑，实现撞击和冲击实验模拟。
此外，本发明冲击物3可根据试验需求改变形状，如车-柱碰撞时可以设置为模拟汽车框架，或实际汽车模型，或其它运载工具以及碰撞物体模型。在试验构件4处可在底部钢梁7上另外安装门式框架，这样能够为试验构件施加轴向力或其他约束，使得试验能够更加贴近实际，以获取更为可靠的试验结果。本发明各部件之间需固定连接时采用螺栓，可拆卸的设计便于在不同场地组装进行试验。
