Wheel loader shovel loading operation tests showed that when the tire slips, it not only causes waste of engine power, but also increases wear. In this paper, regression prediction model is combined with electro-hydraulic proportional control technology. For first time, method adjusting posture working device proposed to realize skid-proof strategy wheel loader. strategy: (1) The technology applied introduced. (2) load spectrum analyzed during operation. Moreover, drive shaft torque, pilot...
The transmission characteristics of physical quantities such as torque, rotational speed and acceleration are important indicators to measure the input output a class gear mechanisms steering gear. Dynamic torque loading testing experiments this index. Sinusoidal signal is often used an excitation source under laboratory test conditions because its convenient generation, arbitrary derivation, flexible adjustment amplitude, frequency, phase other factors. However, in practice, due mechanical...
This paper, a sliding mode based auto disturbances rejection control (ADRC) method is presented for hydraulic active suspension of six-wheel off-road vehicle. First, the low order extended state observer (ESO) used to estimate both external and internal nonlinear uncertain parameters. Next, surface designed make sure robustness system. The experimental results show that ADRC method, together with gives an excellent performance position tracking in presence unknown
A new traction-balanced driving vehicle steering in complicated cross country terrains was developed to improve the synchronous low traction efficiency. The system achieved through hydraulic-resistance control technology applied single-side wheel-side hydraulic motor and securing tyro grounding by active suspension. semi-rail model set up based on methods of estimating wheel-terrain contact angles mobile robots using simple on-board sensors principle pump-control-motor. simulation showed...
In order to realize the functional requirements of hydraulic cylinder installing in leg rehabilitation robots, a new type servo rotary valve was designed with an introduction its structure. The spool may have different locations when actual working conditions are different. To know flow field above case we done thorough numerical analysis. next step basic theory simulation, including modeling, meshing and parameterization, is explained. research treated detail by using fluid dynamics...
In this study, the adaptive adjustment technology, based on an Attitude and Heading Reference System, is applied to loaders, aiming improve rollover protection performance of articulated engineering vehicles. A dynamic stability index for loaders developed, coupling roll angular velocity slope height center gravity. nonlinear predictive model material weight built, in order attain An attitude system proposed, totally electro-hydraulic proportional control adjust working system, so as achieve...

In order to make the active hydraulic suspension system adaptive ground. Taking asymmetric valve controlled cylinder as actuators, a six wheels was designed. It is difficult analysis of system. So this paper established single wheel’s mathematical model instead whole system, designed QFT (Quantitative Feedback Theory) controller which can be solution robustness, researched The results show that it good for tracking performance taking responses timely and meet controlling requirements. This...
This paper presents a parallel hybrid electric bus equipped with an automated manual transmission (AMT) and mathematical model of the powertrain is developed for vibration analysis. The dynamic established by modular modelling approach. A detailed AMT model, considering gear time-varying meshing stiffness, shaft elastic deformation, bearing support, incorporated into model. damping gyroscopic effect gear-rotor in are considered as well. validated experiment data from time frequency domain...
