The mathematical model of the process of giving and soil emission with the working tools of a combined soil-thrower is developed for optimization of various parameters of the developed assembly
Due to strict economical factors, determining a
service life of the structural components of a tracked
timber-harvesting machine (TTHM), including the
support rollers becomes a key issue for the
manufacturers and customers. With that, optimum
relationship between the original cost of the support
rollers and their life cycle cost for maintenance and
repair during the entire service life shall be observed.
The timber harvesting machines are operated under
severe environmental and production conditions. In
the course of operation, they meet variable obstacle,
including stubs, stones, fallen trees, etc., which in
their turn affect negatively the service life of the
support rollers. This article offers a research of the
service life of the tracked timber harvesting machine
support rollers. It describes main defects of the
support rollers, including operational, mechanical
and thermal ones, as well as embedded flaws and
dynamic defects. It also presents the factors affecting
the support rollers' wear. The article presents a
service life-determining model where the following
principle can be generally applied. Service life of a
support roller is determined by its admissible
operational wear-out divided by actual factor for this
support roller and operational conditions
