Wheeled Vehicles

The cross-country capability of multi-purpose wheeled vehicles is one of the most important operational properties of these technical objects. In many ways, it is determined by their traction characteristics. There are a number of ways to improve traction and coupling properties of multipurpose wheeled vehicles, the main ones are the use of various kinds of traction control systems, blocking of  interaxle and interwheel differentials, the use of ballast and several others. Recently, one of the ways to improve the traction properties and cross-country ability of vehicles on soils with weak load-bearing capacity is a regulation of air pressure in the tires of the driving wheels of multi-purpose wheeled vehicles. The paper describes the process of interaction of the wheel mover with the ground surface when the air pressure in the tire changes. The influence of air pressure on the traction properties of wheeled vehicles is established. The system of automatic control of air pressure in tires of mobile cars depending on road conditions is offered. The use of the proposed regulation principle will significantly increase the cross-country ability of multi-purpose wheeled vehicles in heavy traffic conditions, eliminating the subjective factor in the person of the vehicle operator.

Different Soils

In the early 1960s, the USSR geotechnicians were given the assignment to develop the non-rock soils strength characteristics determining method in order to enable the operative tracked and wheeled vehicles passage estimation through the cross country. As a result of theoretical justification alongside the approbation in lab and field conditions by the group of professionals, there was developed a new method of soils strength investigation by the way of joint penetration and rotational cut testing. A new method of estimating soils strength undergone the overall investigation in different soils environments of the European part of USSR, particularly in Karelia – on stripped clays, center and the south of Ukraine – on sands and loess loams, Moscow region – on heavy clay soils. The prototype equipment allowed conducting the research in the cross country, shallow water areas, on the river beds and bottoms of the lakes. In 1970 the equipment and methodology of joint penetration and rotational cut testing were used during the Moon surface investigation by Lunokhod-16 apparatus.

Pressure Control System

In recent years, the research and development of 3D bioprinting device for artificial blood vessels has attracted great attention of researchers. In this paper, the research object is the control system of 3D bioprinting device for artificial blood vessel and the four-channel air pressure cooperative control technology for 3D bioprinting device double nozzles printing is mainly studied. Through the scheme design, working principle innovation, hardware selection and air pressure output calibration experiment of four-way air pressure cooperative control system, the hardware platform of 3D bioprinting device air pressure control system is built. Then, by using the embedded TwinCAT NC PTP software platform based on EtherCAT Ethernet bus protocol, the four-channel air pressure cooperative control is programmed and field experiments are carried out, which realizes the printing process of uniform liquid output and good continuity, and meets the requirements of 3D bioprinting for printing continuity and forming quality. The study of four-channel air pressure cooperative control system in this course is a worthy of application and promotion control method.

Adjustment System

The article analyzes the viability of military vehicles from the effects of conventional damage (bullets, splinters), etc. When fired, a car that stops for a short time becomes an easy target and is destroyed. The presence of a tire pressure control system on the vehicles substantially increases the possibility of continued traffic. However, the opportunities of the mobility adjustment system is limited. The required survivability can only be ensured if special wheels are used. RunFlat (flat tire) is the common name for tireless tire technology. The RunFlat car wheel inserts allow you to continue driving after a tire has been punctured or descended, which can, for example, allow the machine to exit the firing zone. The essence of technology is to strengthen the sidewalls of tires. Hutchinson produces wheel inserts of two types - RODGARD and CRF. The RODGARD RunFlat (Rotary RunFlat) system is capable of providing deflated tires thanks to a special patented design. The CRF RunFlat (Static RunFlat) system is a wheel insert that is used as a single unit of the center of the wheel and tubeless tire. Сommon CSR (Conti Support Ring) system includes a metal ring that is fastened to the rim. The disadvantage of this system is that the support ring will only fit in the high profile wheels. The first cars wish RunFlat in the Armed Forces of Ukraine were KrAZ Cougar and Spartan cars. In turn, the main disadvantages of using wheels with RunFlat include, in addition to the much higher cost, the inability to use the tire after long distances. Airless tire (non-pneumatic) is an innovative development that is a one-piece wheel that can replace both the wheel disk and the pneumatic tire.The main advantage of this design is that the wheel does not require pumping, is not afraid of punctures, is resistant to damage and has a long service life. In this case, the weight of the wheel is almost twice as light, the life of such a wheel is two to three times longer, but the cost is more than twice the price of standard wheels. It is proved that the grip of the road surface in such tires is not inferior to traditional tires, and rolling resistance has decreased to hundreds. The Polaris Defense non-pneumatic wheels guarantee significantly better durability than standard tires and can withstand a 12.7mm bullet. The disadvantage of using non-pneumatic (airless) wheels is to create additional load on the suspension of the car due to their rigidity.
