CTW Automation

CTW is useful when the test is defined by force, movement, velocity and time. The platform is configurable, which makes it powerful for railway components when the actual test envelope fits.
FULL CBP-RELEVANT OFFERING

One platform family covers characterization, programmable motion and production testing.

CTW should be selected from the physics of the test rather than from a generic 'railway tester' label.

RD dyno family

Crank-type damper dynamometers for repeatable force-versus-velocity characterization across different performance classes.

DAMPERFORCE-VELOCITYCRANK DYNO

LA linear actuators

Programmable electric actuators for arbitrary waveforms, longer stroke and more complex dynamic testing.

PROGRAMMABLETRACK REPLAYLONG STROKE

SR-17 spring rater

Configurable spring testing for springs, coil-overs and elastomers where the required load/travel envelope fits.

SPRINGELASTOMERLOAD-DISPLACEMENT

Automation & retrofit

End-of-line systems, software, calibration and legacy-equipment retrofit for repeatable production and lifecycle support.

CAPABILITY MAP

Four ways CTW creates useful test evidence.

01

Characterization

Measure how a component responds across controlled velocity or displacement.

02

Programmable testing

Reproduce custom waveforms and complex motion.

03

Production QA

Turn a lab method into a repeatable end-of-line station.

04

Retrofit & lifecycle

Upgrade controls, software and calibration instead of discarding the installed frame.

GUIDED SELECTION

What kind of component behavior are you trying to reproduce?

Choose the test physics first. Then verify the CTW machine envelope.

RD dyno family

Use a crank dynamometer where the goal is repeatable force-versus-velocity characterization within the machine's stroke and force envelope.

Railway application fit must be established from force, velocity, stroke, duty cycle, fixture, environment and acceptance method. CTW is not automatically a railway-qualified solution for every test.
WHY THIS PRINCIPAL?

Configurable test physics instead of a one-purpose machine.

CTW's USP is flexibility. That is valuable for development labs, component manufacturers and workshops with varied dynamic-test needs, but it also means CBP must protect the boundary between application fit and railway-specific qualification.

PROJECT & TRUST EVIDENCE

Use CTW as an engineering-fit principal, not borrowed historical proof.

Portfolio evidence

Current CBP principal route

CBP's controlled portfolio lists CTW as active for dynamic component testing. Historical MTS/Roehrig damper-test projects must not be re-labelled as CTW deployments unless a direct technical/company lineage is independently established.

WHAT CBP ADDS

CBP decides whether flexibility or railway-specific specialization is the better answer.
