Apply forces of 100 N by means of loading pads (4.5) and a device that can press the cot in 4 directions horizontally, with 2 of the forces in the longitudinal (AB) direction and 2 in the lateral direction (CD) opposite each other (Figure 29). The durability forces shall be applied for 2 000 cycles on each point in turn in the order A, B, C, D or A-B followed by C-D (which equals one cycle).0 c: l. v" ~8 h* C; L" b9 z% ~6 z

问题:婴儿床栏杆 持久性测试,水平施加100N的推力,要求AB施加力度,然后CD施加力度,做2000次。我想问测试仪器怎么设计?普通的仪器能够做到这种程度吗? |
