Description
本申请要求于2020年11月23日提交中国专利局、申请号为202011324315.3、发明名称为“一种轨道车辆碰撞用动态测力系统以及测力方法”的中国专利申请的优先权，其全部内容通过引用结合在本申请中。
本发明涉及轨道车辆测试技术领域，特别是涉及一种轨道车辆碰撞用动态测力系统以及测力方法。
列车一旦发生碰撞事故，会造成重大的人员伤亡，因此，会在轨道车辆出厂之前进行碰撞试验。而碰撞试验需要测定车辆碰撞时的撞力分布情况，以便分析撞击部位的结构和受力状况，从而为设计安全列车车身和改进优化车身结构提供实验依据。
发明人发现，目前的轨道车辆碰撞用动态测力系统中，如图1所示，在碰撞墙1上依次均匀设置多个传感器2，通过传感器获取列车碰撞时的撞击力。其系统成本较高，除此，在该动态测力系统中，轨道车辆直接撞击传感器，而传感器无法承受较大的冲击力，进而使得传感器损坏。
基于此，如何提供一种轨道车辆碰撞用动态测力系统以及测力方法，既能降低系统成本又能提高传感器的耐冲击力，是本领域技术人员亟待解决的一大技术难题。
发明内容
针对于上述问题，本发明提供了一种轨道车辆碰撞用动态测力系统以及测力方法，既能降低系统成本又能提高传感器的耐冲击力。

相较于现有技术，本发明提供了一种轨道车辆碰撞用动态测力系统以及测力方法，该轨道车辆碰撞用动态测力系统，包括：第一平板、至少一个传感器组以及匀力板，其中，每个所述传感器组包括至少两个传感器，所述传感器设置在所述第一平板的一侧表面的预设位置。匀力板位于所述传感器远离所述第一平板的一侧。可见，本方案中，通过在传感器组的一侧表面设置匀力板，通过匀力板实现分散撞击应力的作用，使得作用到传感器上的冲击力变小，进而提高了传感器的耐冲击力。除此，本方案提供的轨道车辆碰撞用动态测力系统中，由于匀力板的存在，还可以使得传感器分布在匀力板的部分区域，使得整个动态测力系统中传感器的总数量要小于现有的将传感器依次平铺的方式中传感器的总数量，可见，本方案能够降低系统成本。
结合附图并参考以下具体实施方式，本公开各实施例的上述和其他特征、优点及方面将变得更加明显。贯穿附图中，相同或相似的附图标记标识相同或相似的元素。应当理解附图是示意性的，原件和元素不一定按照比例绘制。

图2为本发明实施例提供了一种轨道车辆碰撞用动态测力系统的结构示意图；
图3为本发明实施例提供了一种轨道车辆碰撞用动态测力系统的又一结构示意图；

图7为本发明实施例提供的一种测力墙的又一受力云图；
图8为本发明实施例提供的一种测力墙的又一受力云图；
图9为本发明实施例提供的一种测力方法的流程示意图。
下面将参照附图更详细地描述本公开的实施例。虽然附图中显示了本公开的某些实施例，然而应当理解的是，本公开可以通过各种形式来实现，而且不应该被解释为限于这里阐述的实施例，相反提供这些实施例是为了更加透彻和完整地理解本公开。应当理解的是，本公开的附图及实施例仅用于示例性作用，并非用于限制本公开的保护范围。
本文使用的术语“包括”及其变形是开放性包括，即“包括但不限于”。术语“基于”是“至少部分地基于”。术语“一个实施例”表示“至少一个实施例”；术语“另一实施例”表示“至少一个另外的实施例”；术语“一些实施例”表示“至少一些实施例”。其他术语的相关定义将在下文描述中给出。
需要注意，本公开中提及的“第一”、“第二”等概念仅用于对不同的装置、模块或单元进行区分，并非用于限定这些装置、模块或单元所执行的功能的顺序或者相互依存关系。本公开中提及的“一个”、“多个”的修饰是示意性而非限制性的，本领域技术人员应当理解，除非在上下文另有明确指出，否则应该理解为“一个或多个”。
正如背景技术所述，现有的轨道车辆碰撞测试系统的碰撞墙通常采用传感器直接进行撞击试验，或者加盖一层防护盖，将传感器均匀分布在测力墙上，作为独立的单元进行测量。而发明人发现，采用传感器依次均匀排布会导致系统成本过高且无法承受大力值冲击等问题。
基于此，如图2所示，本发明实施例提供了一种轨道车辆碰撞用动态测力系统，包括：第一平板11、至少一个传感器组12以及匀力板13。
其中，每个所述传感器组12包括至少两个传感器121，所述传感器121设置在所述第一平板11的一侧表面的预设位置。匀力板13位于传感器121远离所述第一平板11的一侧。
可见，本方案中，通过在传感器组的一侧表面设置匀力板，通过匀力板实现分散撞击应力的作用，使得作用到传感器上的冲击力变小，进而提高了传感器的耐冲击力。除此，本方案提供的轨道车辆碰撞用动态测力系统中，由于匀力板的存在，还可以使得传感器分布在匀力板的部分区域，使得整个动态测力系统中传感器的总数量要小于现有的将传感器依次平铺的方式中传感器的总数量，即本方案能够降低系统成本。
值得一提的是，发明人在研发本方案的过程中发现：若不安装匀力板，碰撞时，会产生应力集中的问题，即仅接触点能够测试数据，未接触到的传感器不会有测试数据，而试验前的理论分析并不能完整预测出传感器的具体碰撞位置，因此会有很多传感器设置冗余。
其次，单体传感器的量程较小，若为了扩大单体传感器的量程，需增大单体传感器的体积和重量，这为碰撞墙的安装和调试带来许多的困难和不便。除减少传感器数量、扩大测试量程外，匀力板可以有效减少测力时传感器产生的物理形变，保证碰撞墙结构的稳定性，提高测试数据的准确性。
进一步的，为了更大程度的增加匀力板的耐冲击力，本方案提供的轨道车辆碰撞用动态测力系统，如图3所示，还包括：第一加强筋结构21。
该第一加强筋结构21设置在所述匀力板13靠近所述传感器的一侧表面。
具体的，在本实施例中，如图3所示，沿所述传感器的延伸方向X，所述第一加强筋可以为网格结构。当然还可以为其他结构，在此不进行限定。
可见，相比于现有技术，本方案提供的轨道车辆碰撞用动态测力系统中，由于设置了匀力板，使得作用到传感器上的撞击力进行分散，进而本方案中，只需在匀力板下安装几个传感器即可，进而减少了轨道车辆碰撞用动态测力系统的总成本。
除此，本发明实施例提供的轨道车辆碰撞用动态测力系统中，还可以在所 述第一平板靠近所述传感器的一侧表面设置第二加强筋结构，进一步加强传感器的耐冲击力。
示意性的，结合图2-图5，以本发明实施例提供的轨道车辆碰撞用动态测力系统中，每个所述传感器组包括四个所述传感器为例对本方案提供的动态测力系统的工作原理进行说明，如下：
其中，所述传感器分别设置在所述第一平板的四个角处。且，所述第一平板以及所述匀力板的预设位置开设有定位孔，所述传感器的一侧通过所述定位孔与所述第一平板固定，所述传感器的另一侧通过所述定位孔与所述匀力板固定。
除此，在上述实施例的基础上，本实施例提供的动态测力系统还可以包括数据采集模块以及控制器，其中，数据采集模块与所述传感器组信号连接，用于采集所述传感器获取的轨道车辆的撞击力。控制器与所述数据采集模块相连，用于基于所述数据采集模块传输的数据，对所述数据进行处理，得到目标分析结果，以使所述目标分析结果进行展示。
其中，在本实施例中，匀力板使用方式包含几种方式，除此，还可以根据实际情况是否需要使用匀力板，可随需要拆除作为每个传感器独立测试状态，或选择更加适合的组合。除此，匀力板下的传感器的布局可随实际冲击试验的需求合理更改安装个数、分布位置以及量程。布局和使用更加灵活，既可组合也可以分离。
可见，本实施例提供的轨道车辆碰撞用动态测力系统通过测力面板匀力板技术和合理布置传感器的安装位置，能在使用较少的测力传感器的情形下，满足吸能元件和吸能组件的测力需求，整个测力系统可以根据需要上下、左右任意调节，传感器安装、拆卸方便、快捷，大大缩短试验准备时间。此外，传感器表面增加了匀力板，单个传感器不容易过载，解决现有技术无法承受大力值冲击的问题的同时，减少了对大吨位测力传感器的数量需求。
具体的，本实施例提供的轨道车辆碰撞用动态测力系统，可根据试验需求，采用匀力板内置传感器布局仿真列车车头结构，仅需在列车主要撞击部位布置 传感器，完成测力传感器组在第一平板上的布局。完成碰撞后，测力单元输出的信号经放大器放大后送入采集模块进行数据采集，控制系统根据采集数据输出单个测力单元的碰撞力图，也可以定义输出多个测力单元的碰撞力之和，碰撞力能够以二维图、三维直方图的直观方式绘制，如图6-8所示，能够读取全部测力单元的数据，输出整个测力墙的受力云图动画，也可以方便捕捉测力墙受力在各个区域的变化和分布情况，最终实现试验数据和仿真结果的对比。
结合附图可知，三分量测力平台在X方向在施加300kN力情况下，理论分析位移变化量约为0.17mm，Y方向在施加300kN力情况下，理论分析位移变化量约为0.25mm，主方向Z在直径为800mm的范围内施加600kN的力的情况下，位移变化量约为0.87mm。
而碰撞墙要求测试传感器的位移变化量1mm(变形过大会导致冲击力过于集中，影响匀力板下面传感器受力的均匀程度)，因此仿真结果说明本实施例提供的轨道车辆碰撞用动态测力系统能够满足系统要求。
在上述实施例的基础上，本发明实施例还提供了一种测力方法，应用于任意一项上述的轨道车辆碰撞用动态测力系统，如图9所示，包括步骤：
S91、通过所述传感器获取待测车辆的撞击力；
S92、基于所述撞击力，生成所述目标分析结果。
该测力方法的工作原理请参见上述轨道车辆碰撞用动态测力系统的工作原理，在此不重复叙述。

根据本公开的一个或多个实施例，提供了一种轨道车辆碰撞用动态测力系统以及测力方法。
一种轨道车辆碰撞用动态测力系统，包括：
第一平板；
至少一个传感器组，每个所述传感器组包括至少两个传感器，所述传感器设置在所述第一平板的一侧表面的预设位置；
匀力板，位于所述传感器远离所述第一平板的一侧。
一种测力方法，应用于任意一项上述的轨道车辆碰撞用动态测力系统，包括：
