An Analysis Method of the Electro-Hydraulic Rotational Module

Abstract

The paper presents a dynamic research of a rotational module of structure to industrial robot MA 221, to establish the functional characteristics that recommend it for use in the structure of the robot. Actual research performed by two methods: BODE and STEP response of the established the construction parameters values of electro-hydraulic servo-system for stable operation.

A didactically motivated reexamination of a particle’s quantum mechanics with square-well potentials

“…(79) that generates the eigenvalues. Basically, all eigenvaluegenerating equations encountered in the literature we consulted, textbooks [1][2][3][4][5][6][7][8][9][10][11][12][13][14][15][16] as well as specialized papers [31][32][33][34][35][36][37][38][39][40][41][42][43][44], are particular cases embedded in equation ( 79), all with λ = 0 obviously, most of them with symmetrical potential (v 1 = v 2 ) and just a few [3,4,7] with unsymmetrical potential (v 1 ̸ = v 2 ). Very ingenious analytical as well as graphical ways have been proposed and exploited to extract the roots of those transcendental equations; however, the exploitability of these options, although sometimes still rather elaborated mathematically, is possible only for relatively simplified situations, such as the one involving symmetrical potentials for example.…”
