Problems solved by technology

[0004] Due to the change of the traditional transmission form, the current bench test system cannot meet the test requirements of the electric drive system in terms of scheme topology, test function, power level and test method. speed, the existing benches are single-input-single-output or dual-input-single-output, that is, only one output end is connected to the dynamometer for loading test, which cannot meet the steering performance bench test of electric transmission

Abstract

The invention discloses a multi-functional electric transmission test system with a variable topological structure and a test method. The method comprises the steps of: S1, judging whether a drive motor needs to be simulated or not; S2, judging whether a hybrid power mode is carried out for energy supply or not, if not, entering the step S3, and if yes, entering the step S4; S3, judging whether apower supply system needs to be simulated or not; and S4, judging whether the engine needs to be simulated or not, if yes, entering the step a, and if not, entering the step b; a, judging whether a generator needs to be simulated or not; and b, judging whether a generator needs to be simulated. The multi-functional electric transmission test system with a variable topological structure is adopted,electric transmission schemes of different schemes can be tested by simulating an engine, a generator and a driving motor, double inputs and double outputs are integrated in the test system, and thesteering performance effect can be effectively tested.

Description

technical field [0001] The invention belongs to the technical field of electric transmission bench test and testing, and in particular relates to a multifunctional electric transmission test system with a variable topology and a test method. Background technique [0002] Due to the military demand traction, the potential advantages of electric transmission and the advancement of electric technology, electric transmission has become the development trend of tracked vehicle transmission technology.
