Abstract Analyses and resea rch fo r computatio nal pa rameters essential for va rio us theo retical mo dels of track structure are performed and the calculated formulas and the v alue ra nges cor respo nding to these parameters are giv en in this paper. At the same time, the dynamic respo nse characteristic parameters fo r the main compo nents o f standard t rack st ructure, such as mature frequencies and vibra tio n acceleratio ns, measured in situ and thei r rang es as w el l as allowable maximum v alues in some key posi tio ns are presented, which can be used to check the computa tional resul ts by theoretical model.
