Analysis of Stiffness of Truck Door Panel Effective Arrangement of Stiffeners for Improving Stiffness

Since it is more difficult for truck door panels to realize curvature than passenger car door panels, internal stiffeners are mounted between the outer panel and inner panel through the use of an adhesive for ensuring stiffness. For this reason, a problem occurs as to the proper placement of the stiffeners so as to effectively improve stiffness.

By FEM prediction and experimentation, the following have been clarified:

• (1)
  Arrangement of stiffeners for effectively improving stiffness
• (2)
  Stiffness share of stiffeners and outer panel against stiffness
