Aiming at the impact process of a fuel tank, which is a transient energy conversion process, the material absorbs energy through deformation to analyze the mechanical properties of the fuel tank during the impact process. The defense node method is adopted to simulate the dynamic response of the fuel tank during impact. The results show that it can accurately evaluate the safety of the container.

Aiming at the main brake force distribution by using the proportional distribution and the braking force of eddy current retarder with shift, it affected the attachment of wheels on the ground. Through the establishment of vehicle dynamics, relationship of sliding rate with braking force and the eddy current retarder braking dynamics model, the controlled method was researched by relative value as control parameters to the sliding rate and the target rate at the front wheel brake sliding. The sliding rate of the front and rear wheels was compared. Its difference value was control parameter to adjust the eddy current retarder braking force, which do compensation for the rear wheel braking force. This control strategy is carried based on the simulation analysis in Matlab/Simulink. The analysis results show that this method can make full use of road adhesion and improve the braking force and the traffic safety.

In view of the eddy current retarder (ECB) power consumption problem, a new type of split self-excited eddy current retarder (S-ECR) is designed in this paper. In order to verify its feasibility and get the best structural parameters, the influence of the structural parameters on the braking torque of the S-ECR is analyzed. To achieve the goal of improving its braking torque, several programs of different structural parameters are proposed and simulation analysis was carried out by using the control variable method. As a result, the optimal structural parameters of the S-ECR are obtained and the feasibility of the new S-ECR are verified.
