Influence of distribution of streams of capacity between sections on traction possibilities of the jointed transportno-technological system
Engineering Education # 09, September 2010
Article is devoted questions of modelling of movement of the active jointed transportno-technological cars. The objective approach to modelling of the jointed transportno-technological cars is considered. The universal model for research of influence of distribution of power streams between leading elements of the transport car is offered, allowing in a wide range to change the factors influencing efficiency of transport operation. Distribution of streams is offered to be regulated by means of change of parametres of elements distributing power streams (distributing boxes, differentials).
Experimental researches long-base the jointed transportn-technological system
Engineering Education # 09, September 2010
Article is devoted research tests of the active lorry convoy, as special case of the active jointed transport system. The object of research, measurement and control system, the experiment plan are described. Tests have shown high efficiency of application of the active jointed transport systems. The results of research tests showing dependence of force of draught on a hook from a kinematic mismatch in a drive of the second section of the car are resulted. Recommendations about introduction in a drive of the second section of system of the kinematic mismatch providing the maximum value of force of draught on a hook of the car on various types of a soil surface are given
Numerical methods in modeling of the jointed transport systems
Engineering Education # 10, October 2010
Article is devoted questions of modelling of difficult dynamic systems. The jointed transport system, its internal and external relations are presented in a kind three shares the column. The method of object-oriented programming in language of high level Python is applied. At modelling the two-step-by-step method of numerical integration is used. Such approach to modelling allows to reduce dimension of the equations of a solved problem, to increase speed of calculations and to facilitate drawing up of structure of model. Fragments of the program used for the numerical solution of equations of motion of articulated vehicles
Modular principle of modeling of the jointed cars of double appointment
Engineering Education # 08, August 2010
Article is devoted questions of modelling of cars of double appointment. The analysis of system of elastic elements influence on fire power has allowed to formulate the basic requirements to mathematical model. Dynamic processes in real object are replaced by the simplified model in which properties of object essential to given research are kept only, and all other properties are not taken into consideration or replaced with more simple communications. The universal element with which help it is possible to receive any block diagramme wheel or a tracklaying vehicle is offered. In this case the two-mass model with two elastic elements and four degrees of freedom is considered. The model is constructed and the numerical decision of system of the equations is passed, allowing to estimate the response of the jointed car of double appointment to pulse influence from throwing installation.
Interaction of links of the active jointed transport-technological system
Engineering Education # 08, August 2010
Imitating modelling of movement of the active jointed transportno-technological system provides the analysis of all possible conditions of the system considering various road conditions, change of a kinematic mismatch in a drive of wheels of the second section and, as consequence, various variants of power interaction of links. The method based on representation of conditions of system in the form of the focused count, allows to systematise and realise modelling at a design stage and honing tests of the active jointed transport system.
