Development and application of a calculation method for the equivalent conicity in high-speed turnout Zones

Vehicle System Dynamics, 2020
Equivalent conicity is an equivalent mean parameter for reflecting the effects of lateral wheel-rail forces on passenger comfort on trains. Based on the asymmetry of the variable cross-section rails in the turnout zone, this paper views the equivalent ...

Equivalent linkage representation of a railway wheelset for dynamic simulation with kinematic non-linearities

Vehicle System Dynamics, 2022
In this work, a four-link serial-chain mechanism which is an equivalent representation of railway wheelset is proposed. Through this representation, it has been shown that the concepts like instantaneous roll centre, dynamically varying link lengths, and

Equivalent circuits for conical waveguides

The Journal of the Acoustical Society of America, 1988
The acoustical properties of a cone of length L and small-end radius a0 are shown to be representable via an equivalent circuit involving a pair of inertances, a transformer, and a nontapered duct that has the same length and small-end radius as the cone to be represented.

Equivalency of Berkovich and conical load-indentation curves

Modelling and Simulation in Materials Science and Engineering, 2006
The Berkovich indenter, which is one of the most commonly used indenter tips in instrumented indentation experiments, requires a tedious 3D finite element simulation. The indenter is widely idealized as a conical indenter of 70.3° half-angle to enable a substantially less demanding 2D axisymmetric modelling.

Conic systems and sublinear mappings: equivalent approaches

Operations Research Letters, 2004
It was previously recognized that linear conic systems \(Ax=b, x\in C\) where \(A\) is a linear mapping of real Banach spaces, \(C\) is a closed convex cone, are special cases of sublinear mappings: set-valued mappings such that \(\lambda F(x)+\mu F(y) \subset F(\lambda x +\mu y)\). The author observes the converse is also true, giving a correspondence

Conically Equivalent Pairs Of Convex Sets

1997
Classes of equivalent and conically equivalent (K-equivalent) pairs of convex compact sets in ℝn are defined. The problems of minimality (conical minimality) of equivalent (K-equivalent) pairs are stated. In the two-dimensional case a complete solution of the above problems is given.

Research on Equivalent Bending Stiffness of Conical Inflated Beam

Applied Mechanics and Materials, 2012
The conical inflated beams have steady bending stiffness before wrinkles appear according to experimental load-deflection curve, then the deflection distribute function is derived based on the differential function of deflection with variable bending stiffness.

Conical inductor modeling using equivalent circuit technique

2015 IEEE 16th Annual Wireless and Microwave Technology Conference (WAMICON), 2015
This paper describes innovative high accuracy models that have been developed for broadband conical inductors, in particular to predict Piconics' SMT conical series (0.22 to 8 uH). Several models are available from Modelithics which include substrate-scalable versions that have been validated against series-connected inductors on a range of substrates ...
