According to the independence, accuracy and controllability of the driving/braking torque of the distributed drive electric vehicle, a control strategy of differential drive assisted steering was designed. Firstly, the assisted curve under different speed and steering wheel torque was developed and the differential torques were distributed to the right and left front wheels. Then the steering r...

Recently, automatic steering systems for emergency obstacle avoidance have been studied extensively. The control input of such active steering control systems can be classified into the steering angle and the steering torque input. The steering torque based control provides some degree of freedom for drivers to control the vehicle motion, thus it has potential for development as steering assist...

increase haemoglobin synthesis and erythro-poiesis. Further clinical and fundamental research is warranted to establish the possible beneficial effects of (oral) iron chelation treatment on RA activity and the anaemia of chronic disease. of hydroxyl radicals in the presence of ferritin and hemosiderin. Is hemosiderin formation a biological protective mechanism? Biochem J 1986; 234: 727-31. Iron...

metal forming processes, compared with machining ones, reduce production steps and increasemanufacturing speed in addition to saving raw material. in this paper, forming process of column ofa steering mechanism is investigated by finite element analyses and experimental tests; andoptimum die design parameters are found. forming process parameters including die opening angle,bearing length, clea...

All member of family referred to our clinic complaining of white nails. Physical examination revealed clinical features of leukonychia totalis and also the presence of sensor ineural hearing loss (SNHL), palmoplantar keratoderma (PPK) and knuckle pads, the four essential criteria for the diagnosis of Bart Pumphrey syndrome. Three generations were affected with variable presentations in ma...

Morphological variation in the hominoid capitate has been linked to differences habitual locomotor activity due its importance movement and load transfer at midcarpal joint proximally carpometacarpal joints distally. Although shape of bones their articulations are mobility, internal structure shown experimentally reflect, least part, loading direction magnitude experienced by bone. To date, it ...

this research presents a guidance-assistance system for agricultural swing machines. the new automatic steering system controls the vehicle based upon the position of the traces of the previous operation carried out on the field. for each image the trace of the tilled soil by seed drill is placed either on the center line, or on either side of the line. for traces coinciding with images' c...

[Abstract] An automated E/H steering controller is essential for autonomous off-road equipment. This paper presents a methodology for designing the E/H steering controller through a combination of testing and simulation. The steering kinematic model provides the steering linkage gain between the hydraulic actuator and the front wheel. The model makes it possible to close the steering control lo...

There are a variety of factors affecting steering performance on off-road vehicles, including vehicle dynamics and soil stiffness. It is essential to understand the steering dynamics for designing a reasonable electrohydraulic (E/H) steering control system for wheel-type tractor. A computer-controlled E/H steering simulator, consisting of a steering actuator and a steering load simulator, is an...
