Cylindrical helical springs made from round wire and bar - Calculation and design - Part 1: Compression springs
This standard specifies the calculation and design of cylindrical helical compression springs with a linear characteristic, made from round wire and bar of constant diameter with values according to table 1, and in respect of which the principal loading is applied in the direction of the spring axis. NOTE Quality Standards for compression spings will be developed later.
Zylindrische Schraubenfedern aus runden Drähten und Stäben - Berechnung und Konstruktion - Teil 1: Druckfedern
Diese Norm gilt für die Berechnung und Konstruktion von zylindrischen Schraubendruckfedern mit linearer Kennlinie aus runden Drähten und Stäben mit konstantem Durchmesser, mit Werten nach Tabelle 1, bei denen die Hauptbeanspruchung in Richtung der Federachse aufgebracht wird. ANMERKUNG Gütenormen für Druckfedern werden später erarbeitet.
Ressorts hélicoïdaux cylindriques fabriqués à partir de fils ronds et de barres - Calcul et conception - Partie 1: Ressorts de compression
La présente norme spécifie le calcul et la conception des ressorts de compress ion hélicoïdaux cylindriques de caractéristiques linéaires fabriqués à partir de fils ronds et de barres, de diamètre constant ayant les valeurs du tableau 1, pour lesquels la sollicitation majeure est appliquée dans la direction de l'axe du ressort. NOTE Des normes sur la qualité des ressorts de compression seront développées ultérieurement.
