ADHESION OF LOCOMOTIVES FROM THE POINT OF VIEW OF THEIR CONSTRUCTION AND OPERATION, ADHESION TESTS IN 1971

In Report No. 9 the results of the first series of tests carried out between Wadgassen (DB) and Hargarten (SNCF) with Test Machine 18000 were described. The present report contains details of further tests made during 1971 on the Gresy-sur-Aix--Annecy--La Roche-sur-Foron line, in France, and on the Wadgassen--Hargarten line. The relationships investigated were: (1) the effect on adhesion of axle-load, running speed, pinion stiffness, track curvature, sanding, as well as the method of control; (2) the effect on slip of sanding and method of control; and (3) the effect of transmission elasticity on the appearance of stick-slip oscillations. Theoretical analyses of the stick-slip oscillation phenomenon, and adhesion in curves are appended.
