According to the basic principle of the shearer’s travelling mechanism to build the virtual prototype based on UG and ADAMS, and then carry out kinematics simulation of this virtual prototype .The error of angular velocity of every level transmission between virtual prototype and theoretic values . The results can be taken as the guideline for future structural design and dynamic simulation analysis.

This article use Automation Studio simulation software to make analysis on rib tube welding machine hydraulic system.Briefly introduces the software, theoretically analye welding machine hydraulic system, using software to make a detailed analysis on push (pull) acting hydraulic cylinder to push and pull two movements operation By analyzing the stable running speed, equal in size and opposite in direction which is consistent with reality step process.
