Abstract
1. Способ повышения проходимости грунтового и торфяного основания под гусеничным движителем, заключающийся в увеличении опорной поверхности (F) каждой гусеницы при заданной их длине (l) путем увеличения ширины (в) на основаниях с низкой несущей способностью, в придании скосов опорной поверхности траков на краях гусеницы, отличающийся тем, что опорной поверхности гусеницы придают в продольном направлении выпор по радиусу , где ∠ - угол сектора продольного упругого полуконтакта опорной поверхности гусеницы с грунтовым основанием, ∠ - с торфяным основанием, для одноразовой проходимости основания ∠ - угол сектора полуконтакта продольной опорной поверхности гусеницы при «первой критической» нагрузке на грунт, ∠ - на торф, где φ - угол внутреннего трения, с - удельное сцепление основания, - давление структурной прочности основания на растяжение, - центральное «критическое» давление под центром радиальной поверхности контакта гусеницы с основанием, по ширине гусеницы тракам придают выпуклую опорную поверхность под радиус R, осадку гусеницы под центром на основании получают равной , где pcp. - среднее давление на основание под гусеницей в упругом и «первом критическом» фазовом состоянии, Ео - модуль общей деформации, µo - коэффициент Пуассона основания, и минимальной по величине при критической ширине - для грунта, - для торфа, где , - компоненты горизонтального напряжения на вертикальную стенку основания, проходящую через нижнюю точку линии сдвига при среднем критическом давлении , γ - объемный вес основания, а опорные катки выдвигают с опорной поверхностью гусениц на дугу окружности R путем поворота их общих кареток н1. A way to increase the terrain of the soil and peat base under the caterpillar mover, which consists in increasing the supporting surface (F) of each track for a given length (l) by increasing the width (c) on the bases with low bearing capacity, in giving the bevels the supporting surface of the tracks on caterpillar edges, characterized in that the caterpillar bearing surface gives a longitudinal radial extension, where ∠ is the angle of the sector of the longitudinal elastic half-contact of the caterpillar supporting surface with a soil base, ∠ - from peat for a single pass of the base, ∠ is the angle of the half-contact sector of the longitudinal support surface of the track at the “first critical” load on the soil, ∠ is on peat, where φ is the angle of internal friction, s is the specific adhesion of the base, is the pressure of the structural tensile strength of the base , - the central "critical" pressure under the center of the radial contact surface of the caterpillar with the base, along the width of the caterpillar tracks give a convex bearing surface under the radius R, the track caterpillar under the center on the base get equal oh where is pcp. is the average pressure on the base under the track in the elastic and “first critical” phase state, Eo is the total deformation modulus, µo is the Poisson's ratio of the base, and the minimum value for the critical width is for soil, for peat, where, are the horizontal stress components on the vertical wall of the base passing through the lower point of the shear line at an average critical pressure, γ is the volumetric weight of the base, and the track rollers extend with the track surface onto the arc of a circle R by turning their common carriages
