start up/braking

Effect of vertical (parametric) fluctuations trolley bridge crane on its dynamics in cargo rocking in the process of starting / braking

The article deals with the pendular oscillations of the load on the flexible drop (rope) of the bridge crane during its start up/braking. The influence of the vertical (parametric) oscillations of the load wagon on the dynamics of the “loading wagon – rope - load” system is taken into consideration.
