| Summary, etc. | The effects of speed and aspect ratio on the soil reactions under the action of flat vertical tines in clay soil were studied. The experiments were conducted in a laboratory soil bin with the vertical tines of aspect ratio 0.5, 1 and 2; at two depth of operation, 10 cm and 15 cm; at three speeds of 0.11, 0.2 and 0.33 mis and in two moisture contents, 5.83 and 16. 73. It was observed that both horizontal and vertical soil reactions were cyclic and in phase with each other for all the combinations of speed, aspect ratio and moisture content tested. The horizontal and vertical forces (peak value, trough values and average values) were found to increase with an increase of aspect ratio in both moisture contents. The average values of forces in moist soil were hig her than in the dry soil. The soil failure wavelength increased linearly with the increase of aspect ratio at a given depth. The rate of increase showed a similar trends at two operating depths. The specific draft decreased as the aspect ratio increased due to the change of soil failure from three dimensional to two dimensional. The specific draft at 15 cm depth was less than at 10 cm depth. The horizontal and vertical forces increased as the operating speed increased. The rate of increase showed a trend similar to linear or logarithmic. The rate of increase being more in moist soil than in dry soil. The tool forward s peeds used in this study did not show a definite trend of change in soil failure wavelength. The specific draft increased as the tool forward speed increased and the trend of increase was similar to the soil shear strength-deformation relation. The soil moisture content was found to have a significant effect on soil reactions both in terms of forces and soil failure frequency. With an increase of soil moisture content from 5.83 to 16.73, both the forces and ·soil failui:e wavelength increased rapidly. |
