In the sample of electronic universal testing machine, continuous jaw jaw, in parallel orgauge, there will be some special types of materials, and the properties of the material itselfand the applicable environmental requirements. As of now, the solution is not much. Ji'nan Huaheng Test Equipment Co., summed up the following four kinds of seven cases:
*、钢丝、钢绞线由于试样硬度高，内部结构相对松懈，在拉伸实验过程中受力不均匀，夹持试样的钳口易磨损等缘由，夹具一向未得到好的解决。以前是夹铝箔来做，一次实验就需要四片铝箔，浪费较大。现在采用了喷涂金刚砂的电子试验机夹具，打滑问题已经解决，但是断口方位始终未能理想，10根试样的成功率也就一半。
First, steel wire, steel strand due to high hardness, the internal structure is relatively lax,during the tensile test of uneven force, clamping jaw is easy to wear specimens and other reasons, fixture has never solved. Before is the foil to do an experiment, you need fourpieces of foil, large waste. Now the fixture universal testing machine electronic sprayingemery, slipping problem has been resolved, but the fracture azimuth has not been ideal, 10root samples is half the success rate.
第二、有关变形量大的材料因为变形过大，电子电子试验机所以夹持困难，夹具的设计就是一个难点，对设计人员的要求就较高了。
Second, the large amount of deformation of materials because of large deformation, the electronic universal testing machine and clamping difficult, is a difficult fixture design, the design personnel requirements higher.
第三、对需要在高温环境下做的实验，夹具的要求较严格，要耐高温不变形和体积小，所以普通的实验机厂家来说，是比较难解决的，但是耗费的资源较大。
Third, to be in the high temperature environment to do experiment, fixture requirements more stringent, must not high temperature deformation and small volume, so the machine manufacturers in general, is more difficult, but to spend resources greatly.
第四、对批量大，高频率的实验来说，国外遍及采用全自动夹持，对与国内实验机厂家来说，这个问题有待解决，需要结合国外的技术来处理。
Fourth, large quantity, high frequency experiment, foreign throughout using automaticclamping, on domestic experimental machine manufacturer, the problems to be solved,requires a combination of foreign technology to deal with.
