Abstract:
This study focuses on the sudden shaking phenomenon of a sliding door passing
through a corner. This phenomenon requires attention because shaking during
movement can lead to a harsh operation feeling and a short service life. An
experiment based on a test setup was conducted, and the sudden change in the
acceleration of a sliding door panel was measured. Based on multi-body dynamics
(MBD) analysis and a rigid-flexible coupled model of the sliding door system,
the cause of the sudden shaking was determined to be the discontinuous curvature
of the middle rail trajectory. A transition curve was proposed as the solution
for the discontinuous curvature, and Euler’s spiral was applied in the redesign
of the middle rail trajectory. Verified by simulations, the results exhibit
considerable improvement in sliding door movement stability, with large
reductions in the maximum center of mass (CM) acceleration and guide roller
impact force.
