Abstract

In work it is offered a technique of analytical definition of a zone of service of working space of the machine with mechanisms of parallel structure in the plane. The working space of the machine decides at execution of technological movements at an angle on condition of a tool inclination in one party on restriction of movements of bars and overall dimensions of the framework. The working space is conditionally divided into zones. The equations by determination of size of each zone are removed and the general equation for definition of a zone of service of working space is worked out. Influence of design data of the mechanism of parallel structure on the size of its zone of service is analysed. It is established that the increase in a tilt angle of a mobile platform leads to increase in a zone of service, and here the increase in the maximum size of a bar of variable length leads to increase in a zone of service гексапода several times. The increase in the minimum size of a bar of variable length leads to reduction of a zone of service of the machine several times
