STUDY ON ACTIVE / SEMI-ACTIVE VIBRATION CONTROL FOR HIGH-SPEED RAILWAY VEHICLES USING A FULL-VEHICLE MODEL

Detailed Information

Abstract(E)In this research, active or semi-active suspensions to increase the ride comfort of high-speed railway vehicles are studied. Railway vehicles always have parameter variations, for example, the vehicle body weight is varied by the number of passengers or the amount of baggage. Therefore robust control systems assuming a reduced order model of the actual plant are designed. Computer simulation using a three-dimensional full-vehicle model is carried out to compare the effects of using I-I, control theory to those of using LQ control theory. In addition, the effect of these suspension systems on ride quality and running stability is examined.

How to use the search box

You can enter up to 5 search conditions. The number of search boxes can be increased or decreased with the "+" and "-" buttons on the right.
If you enter multiple words separated by spaces in one search box, the data that "contains all" of the entered words will be searched (AND search).
Example) X (space) Y → "X and Y (including)"

How to use "AND" and "OR" pull-down

If "AND" is specified, the "contains both" data of the phrase entered in the previous and next search boxes will be searched. If you specify "OR", the data that "contains" any of the words entered in the search boxes before and after is searched.
Example) X AND Y → "X and Y (including)"  X OR Z → "X or Z (including)"
If AND and OR searches are mixed, OR search has priority.
Example) X AND Y OR Z → X AND (Y OR Z)
If AND search and multiple OR search are mixed, OR search has priority.
Example) W AND X OR Y OR Z → W AND (X OR Y OR Z)

How to use the search filters

Use the "search filters" when you want to narrow down the search results, such as when there are too many search results. If you check each item, the search results will be narrowed down to only the data that includes that item.
The number in "()" after each item is the number of data that includes that item.
