Stability Analysis of Roadheaders

The stability state equations have been based on the calculation of three moment values of x, y, z directions and the sliding state of a roadheader as given in Fig. 1. The method is explained below: Calculate the moment values with respect to C point on the vertical y-axis taken in the plane of the center of gravity that allows us to control if the roadheader turns around vertical axis ...
