| Abstract: | The impact of intelligent three-dimensional parking spaces falling protection board dropping on falling protection obstacle is a nonlinear structure problem. The reliability of falling protection system has been confirmed through a physical test. Drop impact of falling protection system was simulated by nonlinear finite element method. Mechanical properties and dynamic characteristics of the falling protection system in the drop impact process were analyzed by ANSYS/LS-DYNA. The stress, deformation, velocity, and acceleration were obtained. Security and reliability of the devices were confirmed. It is referred to design the three-dimensional parking spaces falling protection system. |
