冲击点 meaning in Chinese
impact point
Examples
- Drop hammer rig was used to perform the impact experiment
冲击点位于中跨的中点，通过落锤装置提供冲击载荷。 - Since the flexural waves in the plate would produce scattered waves when they propagated through the flaw of a plate , the measured signals of a strain gauge contented the direct waves propagated from the impact source and the scattered waves propagated from the flaw
藉由小波转换进行讯号的时频分析，进而求得弯曲波由冲击点至各应变规的波程时间，并计算出弯曲波在各频率中的波群速度。 - Abstract : incompatible element nh11 and hybrid stress element 18 were employed to analyze rock burst occurring in coal face 9108 of sanhejian coal mine . compared with the results from ansys , the two optimized fems can execute more accurate numerical simulation in the research of rock burst as well as other rock problems and lessen the errors from inaedquately meshing in huge calculations due to the limitation of labor and computer time . in addition , the criterion of averaged generalized stress rate was proposed and used to determine the site and moment of rock burst . the given conclusion is in accordance with the face of coal face 9108 very well
文摘:利用优化非协调元和杂交元分析了三河尖矿冲击矿压，并与ansys程序的计算结果进行了比较.认为优化有限元在冲击矿压乃至岩石材料的数值模拟中能给出更为精确的结果，也可减小大型计算中由于人力、机时所限粗分网格产生的误差.分析中，采用了广义平均应力率准则来判断冲击点位置和冲击时刻，所得结论与实际情况吻合 - The current impact experiments have not record the response of force and strain in impact process . elaborate response process of impact for woven composite including impact force of impactor , strain response of different position in the specimen is observed by the special design of impactor and multichannel collection system
目前采用的冲击试验，大多数都没有全面记录冲击过程中的各种响应，本文通过对冲头进行设计，和采用多通道的数据采集系统，得到较为详尽的冲击响应的过程(包括冲击力，试件的正背面响应，离冲击点不同距离的响应) 。
