Abstract: L'invention concerne un procédé de résolution et de dynamique de robot articulé non idéal basé sur un invariant d'axe. Pour un système de contraintes non idéal, une équation dynamique de Ju-Kane d'un système de contraintes non idéal pour un corps rigide en chaîne fermée est établie. Une dynamique de Ju-Kane de corps rigide en chaîne fermée basée sur une chaîne d'axes naturels dans un espace joint surmonte les limitations d'un espace de chaîne d'axes en coordonnées cartésiennes: dans une dynamique de Newton-Euler basée sur une chaîne d'axes en coordonnées cartésiennes, des contraintes par paires cinématiques non arborescentes ne peuvent pas exprimer des contraintes de type crémaillère/pignon et roue/vis sans fin. Dans le procédé, l'équation algébrique de contraintes de la paire de contraintes non arborescentes peut exprimer n'importe quel type de contrainte, et la connotation physique est claire; la complexité de résolution du système d'équations est réduite; la précision de l'équation de contraintes est assurée.

Abstract: A corrosion-resistant conductive film, and a pulsed bias voltage alternate magnetron sputtering deposition method and an application thereof. By adopting a high and low pulsed bias voltage alternating method, a corrosion-resistant protective layer (2), a stress transition layer (3), and a conductive layer (4) are successively deposited on the surface of a substrate (1) to obtain the corrosion-resistant conductive film. By regulating the values of a high bias voltage and a low bias voltage, a deposition time proportion, and the number of times of alternating, a nano-scale multi-layer corrosion-resistant conductive thin film is controlled to grow towards the tendency of high conductivity. The advantages of the bias voltage alternate deposition strategy are that: on the one hand, according to a prepared nano-scale multi-layer alternate coating layer structure, the growth of a columnar structure is inhibited, the formation of a corrosion channel is avoided, and the corrosion resistance is improved; and on the other hand, by using bias voltage modulation, the micro-structure of a coating layer is changed, the conductivity is improved, and the galvanic corrosion phenomenon is avoided, so that the conductive film has better comprehensive performances in the corrosion resistance, the conductivity, and the like, and thus the conductive film has huge application prospects in the fields of fuel cell metal polar plates and transmission line grounding power grid equipment.
