Problems solved by technology

[0002] The stability of the excavator has a great influence on the work of the whole machine. An excavator with good stability can not only ensure safe work, but also enable it to fully exert its excavation capacity within the operating range, and at the same time, the force acting on the slewing bearing device is uniform , to prolong its life, however, the existing excavator stability calculation method is calculated after weighing the whole machine, but it is an evaluation method of excavator stability, not suitable for excavator design

Abstract

The invention discloses a method for optimizing overall stability of an excavator. The stability of the excavator in the front-back direction is optimized, the position of the gravity center of the excavator in the most dangerous full bucket state and the empty bucket withdrawing state is calculated according to the moment balance principle, the gravity center line of the excavator in the two states should be located in a slewing bearing ring in the front-back direction and is close to a slewing center line, the ratio K of the gravity of all parts, materials, fuel oil, hydraulic oil and operators of the excavator to the stabilizing moment to the tipping moment of the tipping line is greater than 1, the overall stability of the excavator during flat ground operation is facilitated, and the function of improving the overall stability of the hydraulic excavator during flat ground operation is achieved.

Description

technical field [0001] The invention relates to the technical field of excavators, in particular to a method for optimizing the overall stability of an excavator. Background technique [0002] The stability of the excavator has a great influence on the work of the whole machine. An excavator with good stability can not only ensure safe work, but also enable it to fully exert its excavation capacity within the operating range, and at the same time, the force acting on the slewing bearing device is uniform , to prolong its life. However, the existing excavator stability calculation method is calculated after weighing the whole machine, but it is an evaluation method of excavator stability, which is not suitable for excavator design. [0003] Therefore design a kind of method that improves the complete machine stability of hydraulic excavator when level ground operation, just the problem that the inventor will solve. Contents of the invention [0004] In view of the deficien...
