Research on Wind Load of the Shell Structure of a Lifting Box-type Thickness Measuring Device

To ensure structural safety in polar environments, this study analyzes the mechanical behavior of a liftable box type thickness gauge. Finite element simulations were conducted across wind speeds ranging from Beaufort scale 3 to 10. Results show that the device’s stress and deformation remain within safe material limits under extreme wind loads. The design of the lower tapered support effectively enhances wind resistant stiffness, ensuring the structure meets requirements for long term polar deployment and accurate sea ice measurement.
