Fatigue Lab


Fatigue lab houses the equipment for evaluating the structural dynamics of vehicles, subsystems and components. These facilities have a
centralized hydraulic power unit capable of supplying 2000 LPM of hydraulic fluid at pressure of 210 Bar, also it is equipped with Strong
Floor, Load Frames, Portal Frames, Bed Plates etc.

Four Poster – 2W/3W & Passenger Cars/LCV up to 3.5 Ton

  • Actuator Rated f/corner : 51 kN
    Max.
  • Acceleration : 39 g
  • Max. Displacement : ±125 mm

Multi Axle Simulation Table (Mast) with Chamber

Providing a full six degrees of freedom (6 DOF), the MAST Simulation Table is used to simulate acceleration, Strain and displacement outputs and reproduce key data collected on proving grounds. The systems incorporate fatigue-rated hydrostatic servo actuators that can deliver more than 14 g of vertical acceleration to payloads beyond 680 kg.

Vibration Shaker

This lab houses the equipment for evaluating structural dynamics of components/aggregates simulating real time loading conditions and
customised vibration tests. There are two Electrodynamic (ED) shakers associated with respective climatic chambers. The ED shakers
perform durability tests for components under dynamic loading at high frequencies.
