Abstract

The invention relates to an automatic modeling method of a hybrid drive system of a series-parallel caterpillar vehicle with a horizontal shaft. The automatic modeling method comprises the steps of determining a D matrix and a Ds matrix, screening structural types, generating unified model matrixes and optimizing a structural type, wherein a final model matrix equation is shown in the description, the Dm represents the composited D matrix, elements on diagonal lines of all lines of the Jm matrix are equal to the sum of rotational inertias of the portions connected with nodes corresponding to the lines, equivalent to the node positions, the portions connected with the nodes are determined through the Dm matrix, the equation represents a composited accelerated speed column vector, and Tm represents a composited external torque column vector. The automatic modeling method can be used for conducting automatic modeling and optimization on the hybrid drive system of the series-parallel caterpillar vehicle and is simple in modeling process, high in modeling efficiency and high in usability.

Description

technical field [0001] The invention relates to the modeling field of a hybrid drive system of a tracked vehicle, in particular to an automatic modeling method for a hybrid drive system of a hybrid tracked vehicle with a transverse axis. Background technique [0002] The tracked vehicle hybrid drive system is essentially an electromechanical compound transmission system, which generally includes two energy sources (gasoline / diesel and battery pack), multiple power components (one or more internal combustion engines and multiple electric / generators) , a complete transmission system. According to the energy transfer mode of the hybrid drive system, the system can be divided into three types: series, parallel and hybrid. The series and parallel systems are simple in structure and relatively easy to model, while the hybrid system generally contains a power coupling device and a confluence mechanism. The power coupling device can couple the power from the internal combustion eng...
