针对现有技术中用于进行地震参数测试的地震测试仪器体积大不易于运输的问题，本发明实施例提出了一种能够快速运输以进行地震参数测试的地震动力参数现场试验系统。
为了解决上述问题，本发明实施例提出了一种地震动力参数现场试验系统，包括：运输平台、作动器总成、电源伺服加载机构、测量控制机构；其中所述作动器总成、电源伺服加载机构都设置在所述运输平台上，其中所述作动器总成可收放的设置在运输平台上；其中所述作动器总成包括“门”字形的反力架，所述反力架的两侧设有支撑缸，所述支撑缸设有伸缩活塞杆；其中反力架中部设有垂直加载油缸；且该垂直加载油缸设有垂直加力活塞杆，在垂直加力活塞杆底部设有用于对地面施加载荷的加载板；其中在反力架的两侧分别设有可沿竖直方向伸缩的伸缩梁，该伸缩梁固定在垂直加载油缸的垂直加力活塞杆上以相对于所述反力架伸缩；其中所述加载板内设有水平加 载油缸，该水平加载油缸的两侧各自设有水平加力活塞杆，且两个水平加力活塞杆各自固定在一条伸缩梁上；其中所述垂直加载油缸的垂直加力活塞杆上设有垂直力传感器和减震机构，该垂直加载油缸的垂直加力活塞杆通过垂直力传感器和减震机构连接加载板；其中该水平加载油缸的水平加力活塞杆上设有水平力传感器。

其中，还包括配重块，在所述作动器总成工作时所述配重块设置于所述作动器总成顶部。
其中，所述运输平台上还设有吊装机构以吊装所述作动器总成。
本发明的上述技术方案的有益效果如下：上述技术方案提出了一种地震动力参数现场试验系统，作动器总成的垂直加载油缸对加载板施加100KN的垂直力，水平油缸对加载板施加最大80KN的水平震荡力。支撑缸支撑在两侧以起到稳定运输平台的的作用，避免水平加载时车身摇晃。橡胶气弹簧位于垂直加载油缸和加载板中间，避免振动传递到油缸而影响油缸寿命，并且在水平方向产生的阻力很小。其中水平加载油缸内置于加载板内，并伸出两条水平加力活塞杆，这两条水平加力活塞杆各自固定在一侧的伸缩梁上。当施加水平振动力时，活塞杆不动，油缸做往复移动。水平反力通过伸缩梁传递到反力架。伸缩梁的伸缩性能，加大了对试验场地的适应性，可对突出地面或下沉到地面以下的不同工况进行试验。

5、外观美学设计准则：本机在设计时注重外观美学和整机造型设计，尽可能使设备造型美观。
根据系统技术要求，本设计方案采用340马力工程车改装，在工程车尾部增加动静作动器总成系统，可施加垂直100KN静态的和水平80KN的动态载荷，该系统可根据实际情况旋转一定角度并根据施加部位高度的不同具有自动升降功能。控制部分安装在车厢内，系统的动力由工程车发动机提供。车厢上部安装有手动吊车，用于将配重块从车厢内部放置于作动器上方。所有部件在系统不工作时都放置于车厢内部，避免设备暴露在室外，使用寿命更长。
