Automatic lane-change maneuvers and obstacle-avoidance systems can effectively reduce the incidence of vehicle collision accidents. However, the trajectory-tracking accuracy and response speed will be affected by both external and internal factors. To solve the above problems, a control strategy is proposed. The strategy proposed in this work can not only effectively improve the trajectory tracking performance under road excitation but also significantly improve the ride comfort.

A multi-body dynamic model of a wind turbine power generation system (WTPGS), with a turbine blade model and hydro-mechanical hybrid power transmission (HMHPT), is developed and simulated. In HMHPT, the hydrostatic power transmission (HPT) improves the system controllability and the gear train obtains higher speeds in the electric generator. The HMHPT's benefits are improved system controllability and higher generator speed. Pump and motor leakages are analyzed based on system performance.

Industrial robots are required to perform a given task repetitively with high tracking precision. Iterative learning control (ILC) calculates the tracking error of each iteration and corrects the output control signals in accordance with a predefined learning operator. This research considers the changes of the dynamics characteristics when the robot has different types of payload. It provides an approach for adaptation of the ILC to the specific payload to achieve faster convergence.

We show how the operational modal analysis of a nonuniform wind turbine tower can be performed and used to acquire effective and reliable test results and dynamic behavior. Results show that a tailor-made genetic algorithm (using auto-MAC as the fitness function) is a practical approach to finding the optimal position of the sensors to obtain the best results for objective modes. We also accessed the updated finite element model with less than 1 % error compared to the frequencies from the test.

This paper introduces several types of multi-engine multi-gearbox marine gearing. A total of two dynamic modeling methods are proposed to predict the coupled vibration of these systems. The dynamic models of four engines with two shafts under different working conditions are established, and the effects of coupling, speed, configuration and power loss on the system vibration are studied.

A nonlinear dynamic model of the noncircular face gear (NFG) was established. A semi-analytical approach, based on HBM and discrete Fourier transformation, is utilized to obtain the periodic responses. The results show that an increase in the eccentric ratio, input velocity and error amplitude will cause the non-rattle, unilateral rattle and bilateral rattle state in succession, and a jump phenomenon will appear when the state of the gears is transformed from unilateral to bilateral rattle.

We discuss a systematic electric vehicle design process. The steering geometry of the vehicle is analyzed, and the turning angle and radius are designed. The displacement of the vehicle under a load is calculated by rigidity analysis. The experimental modal analysis of the real frame and the finite element method are verified for the body-in-white manufacturing process. No-fuse switches and fuses are used to provide overcurrent protection. A solid-state relay is used for current protection.

This paper describes a dynamic mathematical model of a new type of two-stage nutation drive system with double circular-arc bevel gears. The dynamic displacement-vibration coupling model takes into account the gyro torque and side clearance of the nutating gear. A numerical analysis geometric model of the nutation drive system is developed. The geometric model considers the time-varying and contact deformation of nutation gear meshing.

This study carries out the complex eigenvalue analysis of influence factors of rail corrugation by using the three-dimensional finite-element model of a wheel–rail system based on the theory of friction self-excited vibration. The results show that improving the vertical and lateral stiffnesses of fasteners, controlling the wheel–rail friction coefficient below 0.4, and maintaining balanced superelevation can effectively reduce the occurrence possibility of rail corrugation.

In this paper, an effective UKF-based estimation method is proposed to accurately estimate the driving states of vehicles. First, a three degrees of freedom (3-DOFs) vehicle dynamics model is established, and then a vehicle driving state estimation method is designed based on the UKF algorithm. Finally, by using CarSim and MATLAB/Simulink software, the co-simulation and validation are carried out to validate the accuracy of the proposed method under the sinusoidal and fishhook conditions.

A novel bench-scale suspension plant, using magnetorheological elastomer (MRE)-based absorbers accompanied with an adaptive and global neural-network-based tracking controller, is introduced. The global adaptive neural network is used to estimate the uncertain dynamics of the quarter-car model. An auxiliary design system was added to the controller to deal with input constraint effects, and the state was analyzed for its tracking stabilization. All the signals are global, uniform, and ultimate.

The approach in this research includes data visualization and multilinear regression analysis. Multiple linear regression is a standard selection model in the world of data science. The approach turned out to be promising. However, the results reveal that the implemented technique holds a high degree of predictions, and the number of data sets is adequate. It is also observed that errors are in less concentration as the sum of squared errors is zero for every parameter.
