Wind Load Simulation Test for the Vehicle Mounted Extensible Mast System

Abstract:

Based on the Structure and wind load force characteristics of the vehicle mounted extensible mast system, a test method for the wind load simulation of the system was designed. According to the thin wall part structural feature, a method that adding lateral tension at the flanges of the mast was used to simulate wind load. Calculation method of the theoretical wind load force was given, and the transformation formulas between loading force needed and theoretical wind force was put forward, as well the control method of the test based on PID control algorithm was described. Simulation of the force condition under trapezoidal load was given by ANSYS. The results showed that using the load scheme designed, the distribution of stress and strain was almost the same as continuous load, as well as the value and position of the maximum stress and strain.
