WD-400W Track Dynamic Stabilizer--- Training Material Foreword In this book, various components that constitute WD-400W track dynamic stabilizer are introduced, including the knowledge about the structure of the power transmission system, working device, machine body structure, electrical system, hydraulic system and pneumatic system, and brake system etc. This book gives a preferable role of guide for trainees in mastering of the functions, working principle, machine structure, and composition and principles of the systems of WD-400W track dynamic stabilizer.  Chapter 1 General After ballast cleaning from bottom of ballast bed and tamping of a railway track, the track bed is not compacted enough and the lateral resistance and stability of the track is still poor. In this case, traffic safety of train cannot be guaranteed. Therefore, the related specification requires that the train should run at limited speed, which inevitably results in loss of railway transport capacity and gives the busy railway transport a greater burden. In order to shorten or avoid slow-running duration caused by construction and make the track stabilized as soon as possible after construction, so as to ensure safe railway traffic at the specified speed, it is necessary to employ track dynamic stabilizer for track maintenance. This is of great significance for increasingly busy, high speed, and heavy haul railway trunk lines with a large transport capacity. WD-400W track dynamic stabilizer is a self-propelled track maintenance machine that is of an advanced structure and integrates the mechanical system, electrical system, hydraulic system and pneumatic system. In addition, advanced technologies such as electro-hydraulic control, automatic detection, and microcomputer control, etc. are applied to the stabilizer. Therefore, it can realize compaction of track bed and is characterized by complex structure, simple operation, excellent performance, and high efficiency. The outline of the track dy
