Application of Multi-vector Iteration to Identification of Load Distribution in Slewing Bearing of Excavator

摘要

Equilibrium aspect of complex assemblies is important problem to deal with, because such systems are statically indeterminate with usage of classic mechanical methods. In this paper method of solving assembly of this type using numerical computation is shown. The aim of article is to present possibility of using optimization methods such as Newton-Raphson method to finding equilibrium of forces and torques as well as presenting description of object in terms of mechanic, which is need to properly define equation systems to solve. Described method is finally applied to slewing bearing of crawling excavator. Load distribution for every rolling element and change in contact angle is presented.
