Thirdly , the method to calculate the 3 - d dynamic responding of layered transversely isotropic saturated soils to an arbitrary buried source in cylindrical coordinate as well as to an arbitrary harmonious source in rectangular coordinate is presented respectively . based on biot ' s wave theory , the 3 - d wave equations in cylindrical coordinate for transversely isotropic saturated poroelastic media are transformed into a group of governing different equations with 1 - order by the fourier expanding with respect to azimuth and hankel integral transform method or by the double fourier transform method with respect to horizontal coordinates in rectangular coordinate . then , transfer matrixes within layered media are derived under the continuous conditions , drainage conditions and the boundary conditions 基于飽和土的biot波動(dòng)理論,通過fouricr變換,將橫觀各向同性飽和土三維非軸對(duì)稱波動(dòng)方程轉(zhuǎn)化為一組一階常微分方程組,再經(jīng)har止el變換,建立問題的狀態(tài)方程,求解狀態(tài)方程得到傳遞矩陣;利用傳遞矩陣,結(jié)合飽和層狀地基的邊界條件、排水條件及層間接觸和連續(xù)條件,首次給出層狀橫觀各向同性飽和地基在任意地展力作用下的三維非軸對(duì)稱動(dòng)力響應(yīng)的解析解。
This paper provides the general equations of the theoretical contour line and the actual contour line of roller translation follower and roller oscillating follower disc cam in the polar coordinates system and the rectangular coordinates system , respectively . the equations are not only fit for the different layouts of the relative position of follower and cam , but also fit for the different types of cam contour 分別給出了滾子直動(dòng)從動(dòng)件和滾子擺動(dòng)從動(dòng)件盤形凸輪的理論廓線及實(shí)際廓線在極坐標(biāo)系與直角坐標(biāo)系下的通用方程,它們對(duì)于從動(dòng)件與凸輪相對(duì)位置的不同布局方式及凸輪輪廓的不同類型均適用
