There are higher requirements on running stability of the rail vehicle with the incensement of the running speed. The running stability is one of the important indicators of evaluating the dynamic performance of the rail vehicle. In this paper, the whole multi-body dynamic model of the rail vehicle was proposed based on the theory of multi-body dynamics in the software of Simpack. And the lateral and vertical vibrate accelerations of the rail vehicle were simulated when it was inspired by the track irregularities. Then the running stabilities of the rail vehicle were estimated accurately. This will propose basis on the improving design and optimization design of the whole rail vehicle.

In order to meet with the requirements of equipment network integration, flexible customized assembly, lean logistics management and control of assembly process, an intelligent manufacturing model of sophisticated equipment assembly workshop is proposed in this paper. By modeling the requirement of intelligent manufacturing mode in sophisticated equipment assembly workshop, an intelligent manufacturing technology architecture system and its operation mode are built, which include six layers as user layer, core functional layer, system integration layer, intelligent perception layer, resource layer and basic support layer. The key technologies such as the intelligent perception technology of assembly resources by using intelligent information interaction device based on IPv6 and the abnormal early warning method of critical assembly process based on BP neural network are studied. Finally, the analysis is illustrated in the case of a realistic application from a local manufacturing enterprise to highlight the proposal’s feasibility and applicability by applying the proposed intelligent manufacturing model.

In order to improve the efficiency and environment-friendliness of urban rail vehicles, a new hybrid electric locomotive is proposed. The general structure of the proposed hybrid electric locomotive is given and analyzed from a dynamics point of view. The calculation method of power output and its allocation strategy is discussed. A simulation is conducted in HELSP(Hybrid Electric Locomotive Simulation Platform) to verify the performance of the power allocation strategy. The result indicates that the function of allocating power can be properly realized, and the regeneration energy from frequent braking can be absorbed by the power storage of the vehicle.
