Therefore, the paper introduces two kinds of new type side slope protection methods - side protection of molded sack concrete and protection of hinged hydraulic cushion.

Finite element analysis for an articulated underframe of railway freight car body;

In this paper,an analysis on the reason for causing the instability of articulated military engineering machinery is conducted,also,the principles and practical research solutions for currently used articulated ma- chineries are summarized.

With the object-oriented modeling technique,the nonlinear lateral and vertical models of three articulated vehicles are built and some relevant frequency and time domain simulations are done.
