Abstract

The invention discloses an analysis and calculation method for the internal resistance and the power consumption of a crawler travelling mechanism, wherein the specific analysis contents are as follows: (1) theoretical analysis for external characteristics, comprising analysis for a grounding specific pressure, analysis for a subsidence depth, analysis for a ground traction force, and analysis for a running resistance; (2) theoretical deduction analysis for internal frictional resistances, comprising analysis for the frictional resistance generated by the relative rotation of a crawler pin and a pin sleeve, analysis for a frictional resistance between a crawler frame and a crawler, analysis for a frictional resistance at a drive wheel bearing, analysis for a frictional resistance at a guide wheel bearing, and analysis for the engaged frictional resistance of drive wheel teeth and a crawler plate; and (3) determination for a drive torque and a power, comprising determination for a mechanical equilibrium theory and the drive torque, and determination for a power equilibrium theory and the drive power. According to the invention, the internal resistance and the power consumption of the crawler travelling mechanism are systematically analysed and calculated based on strong theoretical research, thus providing a good reference for design for the crawler travelling mechanism; and the calculation pre-processing and post-processing of the method disclosed by the invention are convenient and fast.

Description

technical field [0001] The invention belongs to the technical field of crawler running mechanism, in particular to a method for analyzing and calculating the internal resistance and power consumption of the crawler running mechanism. Background technique [0002] 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 l...
