Abstract:
In order to study the effects of mass center on working performance of tyre roller, this paper analyzed the effects of mass center on dynamic distribution of axle-load, compaction operating quality, straight-line running and rolling resistance, and the analysis was also verified by the testing of 26 t tyre roller. The results show that: the height of mass center influences the dynamic distribution of axle-load, and a lower height of mass center is better, otherwise it will not only affect the adhesion ability of front and rear axle but also affect the start accelerating and climbing performance of whole machine; the mass center should be in the machine's geometric centerline to make sure the symmetry of the overlapping front and rear wheels, which is conducive to the straight-line running and less rolling resistance; the horizontal position of mass center in the machine's geometric centerline between front and rear wheel axis should be sure to make the average unit pressure of ground of front and rear wheels alike, which can ensure the compaction efficiency and uniformity. 5 tabs, 3 figs, 8 refs.
