章节一开头就提到对带有回旋接头的电源线在做摇摆测试时所需要承受的力的要求, - | S& Z9 x* a' _; z: i0 A% d& Y! O但最后的NOTE2那里却说带有回旋接头的器具不需要进行电源线摇摆测试,这不是相互矛盾吗?还是说我的理解有误,求大神解答。谢谢! |% k/ m) S1 z: w& r: b& b作者: tzsn 时间: 2016-8-14 20:29

一般欧洲的带360度旋转功能的就做90角度和180角度的摇摆测试,各1000次作者: BillWei 时间: 2016-8-18 11:47
这个是两个测试,前面说到的是90度的1000次测试,后面是4000次180度的测试。带旋转连接的仅需要做10000次的测试,不需要进行4000次的测试。作者: tzsn 时间: 2016-8-18 21:12
