E . on the basis of drawing up the discrete rod element , the preprocessor procedure forming the element formation of arbitrary orientation rock bolt is worked out . f 在編制離散式桿單元的基礎上,編制了生成任意巖體錨桿單元信息的前處理程序,從而克服了常規的有限元算法中必須將錨桿布置于單元結點的常規做法。
The tasks executed by single robot are limited in some areas . single robot cannot accomplish such tasks as putting operated object in given arbitrary orientation and transporting some heavy and large objects 但是單個機器人并不是萬能的,其所能執行的任務是有限的,如在執行要求把操作的物體放在任意指定的方位、搬運量重體大的物體等任務時,僅僅依靠單個機器人是無法完成的。
For example , if one of the actuator fails , conventional feedback algorithms can no longer position a spacecraft to arbitrary orientation while this algorithm remains viable . preliminary investigations of the mpc approach to attitude control lead to the following conclusions : i 例如:如果飛行器三軸推力器中的某一軸發生故障,那么常規的反饋算法將無法把飛行器定位到給定的方向,但f - mpc算法則可勝任這一任務。
An approach is brought forward to consider arbitrary orientation rock bolt , in this model while forming the calculation mesh , the orientation of the anchor need n ' t consider , only the coordinate formation of starting point and destination of the rock bolt is needed , the formation of rock bolt in combination element can be formed automatically 闡述了任意巖體錨桿的計算模型,該模型在形成計算網格時可不必考慮錨桿的方位,只需賦予錨桿的起點與終點的坐標信息,即可自動形成錨桿在組合單元中的信息。
Based on the method of cell ( moc ) , the effective elastic properties of resined fiber bundle with parallel or arbitrary orientation was studied , and a micro - mechanical model of resined plain - woven carbon fabric was established with the classical laminate theory , then , the method of calculation of the elastic moduli of resined plain - weave carbon fabric was presented , and can be extended to the whole carbon / phenolic composite 基于元胞法( moc )計算了預浸樹脂的平直以及任意取向的纖維束的有效彈性常數。基于經典層板理論用替代層法建立了預浸樹脂平紋機織碳布的細觀力學模型,進而給出了預浸氨酚醛樹脂的平紋機織碳布的彈性模量的計算方法,該方法可推廣到碳酚醛復合材料。
