The Study of a New Manipulator for a Stone Protector of Stony Soil Tillage Implement

This paper studies the motion of novel manipulator that can be used in the structure of stone protectors of soil tillage implements. According to the virtual reality technology-based method the technology of composition of the virtual model of a manipulator and its positions in the working process are described in details. This virtual model is used for composition the video clip, simulating the motion of novel manipulator, which three points are moving along two lines and one curve. The results obtained and the computer program realizing the virtual reality technology-based study of the working process of the virtual manipulators for stone protectors can be used by designers of stone protectors for soil tillage implements.
