In order to improve the structural performance of the out-of-pipe pipe-climbing robot, the out-of-pipe pipe-climbing robot is optimized. The structure and size of the robot was optimized. Static and modal analyses were then performed on key robot components and ANSYS was used for topology optimization. It was found the weight of the optimized frame and clamping arm were respectively reduced by 24 % and 20 %, and the maximum stress was respectively reduced by 46 % and 20 %.

Compared with the hydrostatic CVT used in the current cotton picker, the hydrostatic power split CVT has lower energy and fuel consumption. However, this kind of transmission usually has multiple speed regulation ranges, and the adjacent two ranges will produce impact and affect the driving comfort when shifting. In this study, the shift process of a hydrostatic power split CVT was analysed, and the results prove the feasibility of the application of this kind of CVT in the cotton picker.

This paper proposes a new positional control method for soft pneumatic actuators. The pressure parameter feedback model (PPFM) of the airbag is obtained by adjusting the pressure input through a proportional valve, collecting the air pressure inside the airbag and obtaining the airbag expansion height. The pressure input signal is changed according to the PPFM of the airbag to control the position of the soft pneumatic actuator.

The paper provides a numerical study of a semi-active control strategy for structural vibrations caused by earthquake or wind excitations. A sliding-mode non-linear controller was designed and reinforced by an adaptive switching gain to overcome the chattering problem and perform the stability proven by the Lyapunov stability criterion. The compared and discussed numerical simulation results have shown the performance of the proposed semi-active control.

A terminal sliding mode controller is used to design the controller, and a radial basis function neural network method is used for adaptive approximation of system parameters. In order to eliminate chattering, a fuzzy algorithm is designed for fuzzy control of control gain.

To investigate the effect of the gear transmission system on the dynamic responses of the metro vehicle driving system, a vertical–longitudinal dynamics, model which considers the frame-hung traction motor and gearbox, is established and is validated to be reliable by comparing the simulation results and field test results in both time domain and time–frequency domain in this paper. Compared to wheelset, the gear mesh force has a greater effect on the force state of traction motor and gearbox.

The dynamic load-sharing characteristics of a face gear dual-power split transmission system (FGDPSTS) of an aircraft helicopter are studied. The effects of error, backlash, support clearance, spline clearance, torsional stiffness and support stiffness on dynamic load-sharing performance are analyzed. The load-sharing coefficient increases with the increase of the error, which provides a theoretical basis for the dynamic stability optimization design of the system.

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.

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.

A simple bicycle model considers only geometric and mass properties. Bicycle models considering compliance, tires, and rider posture are available. For the designer, it is important to know if the effect of geometric and mass properties on stability is correctly predicted by a simple bicycle model. Stability indices are calculated by means of bicycle models of increasing complexity. Results show that the simple model correctly predicts only the stability of the single modes.

First, we compare the advantages and disadvantages of existing navigation devices in agriculture and select the magnetic navigation with low cost and high reliability. We then establish the motion model of the table. The fuzzy proportion integration differentiation (PID) control strategy is determined through the model's analysis, and the fuzzy PID controller is designed and simulated in MATLAB. Finally, the test is verified under two different conditions of straight road and curved road.
