Parabolic base resonance type curved surface bulldozing plate and setting method of soil touching curved surface

Abstract

The invention relates to a parabola base resonance type curved surface bulldozing plate and a setting method of a soil touching curved surface. The bulldozing plate is provided with a soil touching curved surface, an upper end face, a lower end face and a rear end face, the contour line of the soil touching curved surface is a complex curve, and the complex curve is formed by superposing a parabola and a sine function curve; the equation of the complex curve is a parametric equation shown in the description: the value range of t is 0-100, the corresponding point when t is 0 is located at the bottom end of the soil contact curved surface, the corresponding point when t is 100 is located at the top end of the soil contact curved surface, A is the amplitude of the sine function curve, f0 is the first-order inherent frequency of soil, and u is the working speed of the bulldozing plate; the soil touching curved surface is obtained by scanning a contour line along a straight line, and the contour line is obtained by taking a parabola as a base line through rotation and superposing a sine function curve on the basis of the base line. Adhesion and working resistance of the soil touching curved surface can be effectively reduced, the energy consumption loss of a bulldozer is reduced, and the working efficiency is improved.

Description

technical field [0001] The invention belongs to the technical field of engineering machinery, and in particular relates to a method for setting a parabolic base resonant curved surface bulldozer plate and a soil-touching curved surface used on a bulldozer. Background technique [0002] Bulldozers are widely used in various fields such as urban construction and mining. As of the end of 2020, the number of bulldozers in my country is about 100,000 units, and the annual fuel consumption is not less than 3 million tons. Reducing the working resistance of bulldozers is of great significance for energy saving and emission reduction. As the direct working part of the bulldozer, the bulldozer consumes about 40% of the power consumed in the work. The geometry of the contact surface of the bulldozer directly affects the desorption and drag reduction performance of the bulldozer. A reasonable bulldozer The soil contact surface structure can reduce the power consumption of the bulldozer...
