摘要:

履带车辆混合驱动系统是一种复杂机电综合装备,为提高其设计与建模效率,提出一种针对混联式履带车辆混合驱动系统的自动化建模方法。以功率耦合装置与汇流装置的建模为例,说明了自动化建模方法的原理,提出了自动化建模的步骤和构型筛选的条件,并给出了消去中间变量动态模型方程的最终形式。利用自动化建模方法在Simulink中建立混合驱动系统模型,编写程序实现了自动化建模过程。以系统构型的优选为例,实现了自动化建模方法的应用验证。结果表明该方法可以自动建立履带车辆混合驱动系统的模型,并排除不合理的系统构型,从而提高履带车辆混合驱动系统的建模效率。

Abstract: Tracked vehicle hybrid drive system is a kind of electromechanical transmission system and equipment. In order to improve the efficiency of system design and modeling, an automated modeling method was proposed for a series-parallel tracked vehicle hybrid drive systems. Based on the modeling of a power combining device and a power convergent device, the automated modeling principles were illustrated and the automated modeling rules and the screening conditions were further proposed. Then the final model equation eliminated intermediate quantity was derived. With the automated modeling method, some tracked vehicle hybrid drive systems were modeled in Simulink to validate the method. The automated modeling processes were programmed. And as an application demonstration for the automated modeling, optimal configuration seeking was described. The results show the method may build the model and screening the configuration automatically, which is a powerful method for rapid and automated modeling of tracked vehicle hybrid drive systems.

Key words: hybrid drive system, tracked vehicle, automated modeling, simulation and validation, optimal configuration seeking
