drive system is the key device of armored chassis. Its working state and reliability influence the maneuver performance of armored chassis directly. In order to simulate the failure process and evaluate the service reliability of drive system in training or battle missions,a new kind of dynamic simulation model and driving simulation platform of the complete drive system were established based on virtual prototype and finite element technology in this paper. Using the platform, the kinematics and dynamic characteristics of drive system were studied and analyzed in detail,the dynamic load spectrum of key components was obtained,the service life was predicted, and the service reliability evaluation results were provided. A simulation example of transmission gear was shown to illustrate the simulation and evaluation process. The result proves that the simulation method not only can be used to compute and evaluate the service reliability of complex mechanical mechanism, but also has high precision and reasonable computational cost. Therefore,simulation and reliability analysis based on virtual prototype of the armored chassis drive system will provide scientific reference for the formulation of armored chassis reasonable repair cycle.

To investigate the re-adhesion and dynamic characteristics of the locomotive drive system with wheel slip controller,a co-simulation model of the train system was established by SIMPACK and MATLAB/SIMULINK.The uniform running and starting conditions were considered,and the influence of structural stiffness of the drive system and the wheel slip controller on the re-adhesion and acceleration performance of the locomotive was investigated.The simulation results demonstrated that the stick-slip vibration is more likely to occur in locomotives with smaller structural stiffnesses during adhesion reduction and recovery processes.There are many frequency components in the vibration acceleration spectrum of the drive system,because the longitudinal and rotational vibrations of the wheelset are coupled by the wheel‒rail tangential force when stick-slip vibration occurs.In general,increasing the structural stiffness of the drive system and reducing the input energy in time are effective measures to suppress stick-slip vibration.It should also be noted that inappropriate matching of the wheel slip controller and drive system parameters may lead to electro-mechanical coupling vibration of the drive system,resulting in traction force fluctuation and poor acceleration performance.

Based on a two-wheel rear-drive hub motor drive prototype car carried by an automotive enterprise,for the sudden frustration and abnormal impact problem of the driving system in the process of starting and driving,we find the causes of the problem through the methods of modeling,simulation and analysis,monitoring the change curve of motor torque,and put forward the solutions of pedal analysis,parameter optimization and moment filtering from the root of the problem.We solve the problems of setback and abnormal impact noise,improve the riding comfort of the prototype car by implementing the above scheme on the prototype car.It provides a reference for the follow-up research of hub motor drive system.

＜正＞The performance of the large power AC drive system for rolling mills should meet the need of production technology and adapt to the requirement of the electric network.AC-AC converters have been successfully applied in the large power main drives for rolling mills being low speed and large torque.But in the drive systems for cold rolling mills being high speed,AC-DC-AC converter systems should be used.In the paper,the large power three-level AC-DC-AC converter system with IGCTs is introduced.And the switching process of IGCT is considered.Then with a series of experiments,the property of the converter is examined.The experiment result indicates the converter reaches the design requirement and it shows excellent performance.The three-level AC-DC-AC converter system with IGCTs whose rated power is 7.5MVA has been developed and put into use.And it is estimated that the AC-DC-AC converter system will be used in the drive for rolling mills in the near future.
