Electrical Actuator Fatigue/Static Test System

Multi-function

Capable of testing various bicycle parts in one machine:

  • Frame (horizontal/vertical force by single actuator, pedaling force by dual actuators)
  • Handlebar and stem (out-phase or in-phase force by dual actuators)
  • Crankset (pedaling force by dual actuators)
  • Seat post (vertical force by single actuator)
  • Fork (vertical force by single actuator)
  • Fork and stem assembly (single force or out-phase force by dual actuators)

 

Test modes

  • Fatigue test conforming to ISO 4210: 2023
  • Static pressure holding test
  • Auto multi-stage test (continuing handlebar out-phase/in-phase test)
  • Crack detect mode: part crack check by slow motion control

 

Advantage

  • Plug and play, just need 220Vac power
  • Capability of installing vertically, inclinedly, or horizontally
  • Compact actuator size, easy disassembly and movement
  • Quick release design for easy moving actuator left/right and up/down
  • Energy saving and less carbon emissions: power consumption less than 4 kW
  • Low noise/pollution: noise less than 75dBA
  • Simple maintenance: 3 years guarantee for actuator, easy replacement by users
  • High efficient real-time control in 4kHz/actuator control loop, without disturbing by Windows operation
  • Small machine size
  • Large testing space

 

Rich software functions

  • Simple, intuitive and clear information user interface
  • Chinese/English interface
  • Auto actuator zero-force tracking, convenient for installing testing parts
  • Smart PID control for different part stiffness
  • Setting of auto multi-stage test
  • Test resume: test can resume from interrupt or temporarily stop
  • Provide force and displacement real-time graph
  • Provide force and displacement trend graph
  • Record testing waveform and trend PDF format test report
