1.支撑于下;支撑;支持
1.to prop something up from underneath
1.Method On an impact tower, the impact tests were carried out based an rivet or buffer underprop supporting system.
方法采用两种支撑方式，分别对两种假人在水刹车冲击塔上进行冲击测试比较。
2.The machine is canceled the underprop, wheel and axle are directly fixed on the reducer, so the machine is lightened its weight;
本机型的设计取消了支撑架，轮轴直接固定在减速器上，减轻了重量；
3.Optimized Design of Dongfeng11 Locomotive Salvation Vehicle Underprop Base on FEM Simulation
基于有限元仿真的东风11型救援小车支撑块结构优化
