Bench of tiredness in rotational bending
Model SFT 400

  • Bench SFT 400 makes it possible to study the various parameters intervening in the process of tiredness mechanical
  • Counting of the number of cycle to the rupture.
  • Variation of alternating loads by application of a variable effort/rotational bending.
  • The various shapes of provided test-tubes.
  • Teaching handbook included.
  • Designed, manufactured to industrial standards.
  • The didactic interest of the SFT 400 is directed towards the IUT, schools of engineers and universities in mechanical sections.

Application
  • Description of the parameters inducing the rupture by tiredness
  • Layout of curve SN of Wöhler
  • Statistical tiredness approaches

Specifications

  • Structure :
    - In shaped anodic aluminium of section 45mm*45mm
    - 4 feet adjustable shock absorbers
    - Transparent cap maintained closed by 2 knurled nuts
  • Electric box :
    - Metal electric box
    - Desk of integrating piloting in frontage: Disconnecting switch, circuit breaker principal, differential, emergency stop, walk general stop with indicator, walk/engine stoppage, indicator driving state and of general power supply
    - Bill-poster LCD of the number of cycle before rupture/reset by button in frontage
  • Revolving part :
    - Three-phase asynchronous motor 2850tr/min - 230/400V - 50/60Hz
    - Tree guided by ball bearings
    - chuck has tightening conical for immobilization of test-tube (key specific provided)
    - 1 inductive detector for counting of the number of cycles of the test.
  • Device of load application :
    - A serrated roller makes it possible to regulate the effort exerted at the end of the test-tube until 30kg
    - A dynamometer makes it possible to measure this effort
    - The effort is applied at the end of the test-tube by a bearing related to the support of load application
    - 1 breaking process detector of test-tube/starts the automatic stop of the counting of the number of cycles
