| 任何东西在使用过程中都有可能出现突发状况，当然环形链条索具也不例外。 Anything in use may occur unexpectedly, of course, the ring chain rigging is no exception. 环形链条索具在正常使用过程中有时突然就不工作了。环形链条索具在使用的时候经常不是单独的使用，往往是很多复杂的结构组合在一起使用，这就要求我们在力学上考虑到受力分析对环形链条索具延展性的影响。 Ring chain rigging sometimes suddenly ceases to work during normal use. Ring chain ropes are often not used alone, but are often combined with many complex structures. This requires us to consider the influence of force analysis on the ductility of ring chain ropes in mechanics. 当然从这一点来说环形链条索具应该具有一定的延展性比较好，因为在起吊的时候如果突然受力而没有拉伸特性的话那么环形链条索具本身就会承载过大的瞬间拉应力，这种拉应力很容易超过其所能承受的极限应力。而如果有一定的弹性拉力的话就会在起吊的时候起到一定的缓冲作用这样能够大大降低断裂的几率，尤其是环形链条索具。 Of course, from this point of view, the circular chain rope should have a certain degree of ductility, because if there is no tension characteristics when lifting, then the circular chain rope itself will bear excessive instantaneous tension stress, which can easily exceed the ultimate stress it can bear. If there is a certain elastic tension, it will play a buffer role when lifting, which can greatly reduce the probability of fracture, especially the ring chain cable. |
