Analysis and calculation method of internal resistance and power consumption of crawler attachment

Abstract

The invention relates to an analysis and calculation method of internal resistance and power consumption of a crawler attachment. The specific analysis content comprises: (1) external characteristic theory analysis comprising the analysis of unit pressure of ground, sinking depth, ground traction and driving resistance; (2) internal frictional resistance theoretical derivation analysis comprising the analysis of frictional resistance generated by the relative rotation of a track pin and a pin bush, frictional resistance between a truck frame and a caterpillar band, frictional resistance at the position of a driving wheel bearing, frictional resistance at the position of a guide pulley wheel bearing and meshing frictional resistance of a driving bearing and a track shoe; and (3) the determination of driving torque and power comprising the determination of mechanical equilibrium theory and driving torque, and the determination of power balance theory and driving power. On the basis of solid theoretical research, the invention analyzes and calculates the internal resistance and power consumption of the crawler attachment and provides favourable reference for crawler attachment design; and the software of the invention has convenient and quick pretreatment and posttreatment.

Description

technical field The invention relates to an analysis and calculation of internal resistance and power consumption, in particular to the analysis and calculation of internal resistance and power consumption of a crawler belt traveling mechanism. Background technique Tracked vehicles are a kind of "self-paving" road vehicles. Due to their strong traction and adhesion, adaptability to harsh ground environments, and good passing performance, they play a very important role in modern military, agriculture, energy, construction and other fields. effect. The crawler running mechanism is an important part of the tracked vehicle. It is a walking device that is more adaptable to the road surface than the wheeled walking mechanism. The crawler running mechanism can run on roads where the working environment is harsh and the wheeled device cannot travel, such as deep snow, swamp, soft mud and sand and gravel, and the grounding specific pressure of the crawler running mechanism is much...
