Design design of technical systems

The improvement of the methods reducing dynamic loads in elements self-propelled transport machines and transported goods is based on results analysis phenomena that occur during their operation, which due to growth load, increase working speeds, combination loading unloading operations with other technological operations, productivity.
 To prevent damage ensure traffic safety, packaging artificial cargoes are secured car bodies, train carriages ship holds wire ties, thrust spacer bars, tying methods.
 But transportation, as a result stretching breaking stretch marks pulling out nails, damaged, moving body, wagon or hold. Therefore, it very important at design stage fastening structure establish possible movement well within given limits order load.
 authors proposed method calculating load fluctuations body truck using example two different weights. A kinematic diagram machine sequential elastic coupling was built study nonlinear horizontal oscillations loosely vehicle carried out.
 According research, graphs dependences dimensionless amplitude weight relative depending gap between fasteners were constructed. Maps regions stable movements constructed region unstable shown. It noted although such an area quite small, but under certain conditions weakly cargo, can cause accident.
