In the paper , on the basic of a mature analysis theory of slope reliability , study on the combination of security coefficient implicit function and transient surface method is carried through 本文以現(xiàn)已成熟的邊坡穩(wěn)定性分析理論為基礎(chǔ),對穩(wěn)定性系數(shù)隱式方程和響應(yīng)面法結(jié)合進(jìn)行了研究。
Second part , using approximation method and implicit function theorem , we obtain the existence of large amplitude 2 - periodic bouncing for damped linear impact osillator with mutiple impacts in one period 在第二部分里,我們運(yùn)用逼近框架與隱函數(shù)定理,對于帶小阻尼的線性碰撞振子,證明了在一周期內(nèi)發(fā)生多次碰撞的大振幅2 -周期解的存在性。
According to the problem that performance functions for structures are difficult to be explicit expressed , a method based on neural network was utilized to transform the implicit function into an explicit expression 摘要針對結(jié)構(gòu)可靠度分析中極限狀態(tài)方程不能明確表達(dá)的情況,結(jié)合神經(jīng)網(wǎng)絡(luò)技術(shù),提出了隱式極限狀態(tài)方程轉(zhuǎn)換為顯式表達(dá)式的方法。
Then with implicit function theorem the flexible workspace is dealt with . by using the jacobian matrix of the hybrid input mechanism , the sensitivity of output is obtained . then the condition number of jacobian matrix is derived 進(jìn)而研究平面閉鏈機(jī)構(gòu)的柔性工作空間,并利用隱函數(shù)定理快速地推導(dǎo)出平面閉鏈5r和4rp機(jī)構(gòu)的工作空間的邊界條件。
In this paper , this framework is applied with a new supershape implicit function that is based on the notion of radial distance and results are presented on realistic models composed of hundreds of hierarchically globally deformed supershapes 這就是實(shí)體建模的概念,更專業(yè)地說,就是實(shí)體構(gòu)建幾何csg 。 csg通過布爾運(yùn)算能對圖元進(jìn)行自然簡便和快速的組合操作。
