“…The simulation analysis of different stern structure forming charges by AUTODYN software was used to obtain the forming parameters and morphology of 2 types of destructive elements. The optimum stern radius is 22.5 mm and the optimum stern inclination is 45° [ 4] . Xuan Shifeng and Shang Wei et al used numerical simulation to compare the jet formation characteristics of the combat section without a truncated top and with a truncated top charge, and the results showed that the jet length increases and then decreases as the diameter of the truncated top increases [5] .…”

To study the effect of multi-mode combat part destruction, in this paper, we use AUTODYN simulation software to simulate the effects of dual-mode combatants on the shaping of the destruction element under different structures of the charge cover, charge height, and detonation method, and determine the optimization scheme of dual-mode combatants through orthogonal optimization. This study has a certain reference value for the structural design of multi-mode warheads and the study of damage effects.

“…It improves the underdamped problem of the valve-controlled cylinder system and prolongs the service life of the components. This research has great development space and practical value in hydraulic quadruped robot [6], hydraulic steering system [7], material presses [8], excavators [9] and other occasions with large impact force. However, the high power density leads to the complexity of the internal flow channel of the damper, and the hysteresis characteristics are more obvious, which seriously affect the output accuracy of the damping force.…”

Magnetorheological dampers (MRDs) are applied to hydraulic systems, which not only improve the underdamped characteristics of valve-controlled cylinder systems, but also help hydraulic actuators to resist high load impact. However, the high power density leads to the complexity of the internal flow channel of the damper, which seriously affects the output accuracy of the damping force. It can lead to the fact that existing dynamics models cannot accurately describe the hysteresis characteristics of the MRD. Therefore, this study proposes a simple and general dynamic model of MRD, which solves the problem that existing models are complex and difficult to invert. Firstly, the hydraulic damping actuator (HDA) with the series MRD is taken as the research object. Based on the stress-strain hysteresis characteristics under the cyclic constitutive model, the hyperbolic tangent curve is reorganized and normalized. It can accurately describe the yield formation and yield dissipation stages of the hysteresis loop. Secondly, the relationship between the parameters of the dynamic model and the current is obtained according to the mechanical experimental data. Then the inverse model of the MRD is established by using the method of section-backstepping. Finally, in the static experiment, the Mean Absolute Percentage Error(MAPE) of the force at different velocity is less than 7.5%; In the dynamic experimental test, the MAPE of the force is 9.7%. The inverse dynamics model is verified to have high tracking performance under both static and dynamic forces. And it also indirectly confirms the effectiveness of the forward model.

“…A pump-controlled steering is proposed by Daher et al [4] where the volumetric displacement of the hydraulic pump is controlled in order to control the steering, the study does not consider the redundancy. Similarly, Wang et al [5] proposed a steering with dual-mode which has two steering control elements, hence not according to the ISO standards [6] which does not allow to have separate steering control elements for redundant steering. A Steer-by-Wire (SbW) for HEMM has been proposed by authors that has potential to fulfil the required safety standards in a previous article [1].…”

The articulated Heavy Earth Moving Machinery predominantly use hydrostatic steering, because of its reliability and redundancy. In earlier studies an energy efficient Electro-Hydrostatic Steering System was proposed, which works on Steer-by-Wire principle and comply with the safety standards. This paper presents co-simulation of a wheel loader model with hazard-free Steer-by-Wire. A cosimulation model using three software platforms; Mevea for multibody dynamics and mechanics, Simcenter AMESim for hydraulics, and MATLAB/Simulink for hydraulics, control, and data analysis, is created to analyse the hazard-free functionality of the steering. The simulation model of primary steering, which is an electric motor controlled Electro-Hydrostatic Actuator, is validated experimentally. In these heavy machines, as required by the standards there shall always be a secondary steering system for redundancy. The secondary steering, which is through a proportional control valve is modelled using the characteristics of the commercial product. There are five possible hazard scenarios in steering application of such machinery, which have been identified by the authors in earlier publication. These five hazard scenarios are realised in co-simulation model by modelling the respective faults in the primary steering, and the effectiveness of the hazard-free functionality in the steering is analysed. The study demonstrates that the novel Steer-by-Wire for articulated steering can effectively mitigate the potential hazards associated with steering in Heavy Earth Moving Machinery, moreover, co-simulation model provides an effectual mean to analyse the novel solutions.
