The mesh of copper tubes and loading ways of the balls are the key problems during three dimensional fe simulation of ball spinning of inner grooved tubes 摘要内螺纹管滚珠旋压三维有限元模拟中，铜管的网格划分和滚珠加载方式是模拟的关键问题。
Because of the difference of loading way and load transfer mechanism , its transferred result has some deflection with traditional load test 但因加载方式与桩身实际受力状态的不同以及荷载传递机理的差异，使得测试结果与传统静载存在一定的误差。
Under reciprocating loading , the interaction relation of pile and earth are influenced by circulating frequency , the way of load addition , stress route and other 而在往复荷载作用下，桩土相互作用关系还受到循环次数、加载方式、应力路径等影响。
The influence of the strength of core concrete , the ratio of steel content , confinement coefficient and loading format on the mechanical properties of rpc filled in steel tube short columns 分析了核心混凝土强度、含钢率、套箍指标、加载方式等参数对极限承载力的影响。
2 . tow different types of power loading condition were applied on chips respectively . the transient thermal analysis was conducted to determine temperatures vary over time 2 .以两种不同功率加载方式进行自然对流换热条件下的封装瞬态热分析,得出封装体温度随时间的变化规律。
In this experiment , some conditions , such as the strength of concrete , the area of angle steel , ends of the steel and modes of loading are considered , and the influence of them are analyzed 本次试验从混凝土强度等级、粘钢面积、锚固情况和加载方式这几方面入手，研究了这些因素对加固效果的影响。
The load adopted in the model are very similar to real working conditions of the short leg walls in the actual structures . works accomplished in this paper can replace some experimental studies 论文采用的加载方式接近构件的工作实际，主要结论具有一定的理论和实践意义，数值分析成果可取代或部分取代构件的试验研究。
This kind of load can not be content with the increasing request of process of test load , when the test is needed to simulate actual working condition of the products 试验人员调整的依据是他们对设备的使用经验和双眼看到的测试设备显示的当前载荷。随着对试验加载过程要求的提高，原有的人工液压加载方式已不能满足这种要求。
Which arouses think in the change of effective stress during uninstalling loads . as the problem is concerned , two - direction load , which differences from the usual load process , is presented 针对这一问题，本文对目前研究较少的卸载后有效应力的变化规律做了思考，提出相对于一般加载方式的双向荷载作用(加载?卸荷)的概念。
Calculation results illustrate that decreasing the blade hub - to - shroud loading level can increase the impeller adiabatic efficiency , and that aft - loaded impeller can obtain higher impeller adiabatic efficiency 计算结果表明，在一定范围内，降低叶片轮缘轮毂方向的负荷可以提高叶轮效率，后加载方式可以改善离心压气机叶轮性能。
