The transportation industry, including motor vehicles, aircraft, rail, marine, commercial, off-road and defense vehicles, as well as infrastructures, energy sectors, raw materials, manufacturing, health and food industries all experience significant issues with corrosion which results in billions of dollars of loss each year. Corrosion education and prevention is essential to improve and increase the service life of parts and components which may have a significant impact on the economy of various industries and nations.

A sudden pressure loss can lead to an instability of the car. This instability can lead - without aid of systems such as e.g. Electronic Stability Control (ESC) - to an emergency situation, possibly resulting in an accident. But also with an ESC system such a situation is an unusual application case, because the vehicle system (car+tires) properties change very rapidly, resulting in a highly dynamic response of the system and moreover to a fuzzy and unclear description of the vehicle system. From this point of view, a proper validation and verification of an ESC system for such an application seems to have a big safety relevance. The authors have set up a simulation case to simulate a sudden tire inflation pressure loss and its consequences to the car stability. Using this simulation setup enables a CAE engineer to pre-develop ESC systems and/or to validate and test these systems for a realistic and relevant use case.

A three-dimensional finite element model of radial tire 205/55R16,established by ABAQUS software,is used to simulate tire force and moment properties. Drum tests are designed to validate the simulation model’s reliability. To investigate the impacts of PCR contour design theory on tire force and moment, a modified string balance contour theory is presented, based on string balance contour theory, which simplifies the belts pressure share ratio as trapezium. And a program for calculating tire’s contour is compiled. Different tire contours are designed according to different belt pressure share ratios. One of the contours is selected according to the positive affect to cornering stiffness. Compare the selected newly designed tire with the original one, it is found that the newly designed tire’s contact area, longitudinal stiffness,lateral stiffness,camber stiffness and cornering stiffness increase while its radial stiffness decreases.

Distinguished from the conventional internal combustion engine vehicles, most of the pure electric vehicles are equipped with only a fixed-ratio reduction gear, because of the wide speed range of the electric motor. For most of the vehicle’s speed and acceleration requirements, they can be satisfied through application of only a fixed-ratio reduction gear. However, within some speed range, the operation efficiency of the electric motor is relatively low, which affects the overall energy efficiency of the electric vehicle. Thus, application of a two-speed gearbox is able to remain the electric motor working within high-efficiency range during the whole operation conditions, which has a good potential to further improve the electric vehicle’s energy economy. Based on the above analysis, in this paper, gear ratios of a two-speed transmission system are optimized for an electric passenger car.

Large rear-dump mining trucks often suffer from rock impacts which cause adverse vibration during loading operation, resulting in structural damage and deteriorated fatigue life of the body. To decrease the body vibration under heavy rocks’ impact loading, an innovative active suspension system concept was put forward for the rear-dump mining trucks in this work. The new system was developed using simulation methods in three steps. Firstly, a simplified multi-body system dynamic model of a 360t load capacity rear-dump mining truck under rock impact was built in ADAMS as a base model. Secondly, by using the joint simulation method, the base model was translated into a system function module in MATLAB, and an active PID control system to adjust the suspension force was designed base on the modules in SIMULINK. Finally, parameter optimization was conducted to guarantee the proposed control system a better damping performance during the loading process.

Speed bumps are a common traffic calming device that uses vertical deflection to slow motor-vehicle traffic in order to improve traffic safety conditions. Such vertical raising of road pavement had been studied and commonly used as a passive method to reduce the speed of vehicle. Speed bumps generally slow vehicle speed to 5–10 mph (8.0–16.1 km/h), and some to 10–20 mph (16–32 km/h). On one side, speed bumps/humps effectively calm traffic speed to protect pedestrians. On the other side, it may cause vehicle damage and passenger discomfort. In Sweden, an evaluation of spinal stress in bus drivers against ISO 2631-5 required that a driver shall encounter less than 150 bumps in a day at the maximum acceptable speed 10 km/h. When a vehicle touches a speed bump, the speed bump receives the energy transferred by the weight and velocity of the vehicle. Harvesting the vibration energy from speed bump becomes a valid solution in areas where grid electricity is economically available.
