Stress analysis on suspension bridge trainer kit is a bench top kit which is designed to illustrate the behavior of suspension bridge in various load cases such as point load and distributed load in terms of tension and compression forces applied on the suspension bridge.

                                     
  • The educational unit represents a suspension bridge; The Bridge consists of two parallel supporting cables with a roadway suspended between them.
  • The unit includes U-shaped hangers that are used as vertical cables; they are attached to the main supporting cables at regular intervals, and hold the roadway.
  • The Deflection rollers act as pylons and the roadway acts upon the supporting cables as a distributed load, and can be loaded by additional weights.
  • The educational unit is provided with two roadways with different stiffness: one stiff and one elastic roadway.
  • The stiff roadway has a hinge in the middle, this hinge permits internal moments in the roadway occurring in response to uneven loading to be visualized.
  • The educational unit allows the study of Cables with different dead-weigh when the setup is without the roadway, this happens by attaching additional point loads directly to the supporting cables.
  • The tensile forces in the supporting cables are determined with the aid of weights.
  • The maximum sag is measured using a scaled rule. The scaled rule is fixed to a cross-arm.
  • All the component elements of the experiment are clearly laid-out and housed securely in a storage system.
  • The complete experimental can be setup on the mounting frame.
