Justification of the parameters and compiling of the forest machine chassis can not be performed without determining the weight of the load. The weight of the load depends on the wood density. The wood density within the growing tree is heterogeneous. The aim of this study is to develop mathematical models to calculate the average density of the tree trunk area depending on its location in the trunk. The research is based on the construction of approximating dependences of changes in the average wood density in the longitudinal direction of the trunk by minimum deviation method. The obtained mathematical models establish the relationship of density changes in the longitudinal direction of the trunk for four forest-forming species of the Republic of Karelia: pine, spruce, birch and aspen.
