Freshwater scarcity poses a major challenge to sustainable agriculture. To alleviate water stress during critical crop growth stages, this study proposes an integrated wind-photovoltaic (WPV) power generation and air condensation water harvesting device, and investigates the fracture-prone cylindrical support structure under realistic operational loads. A finite element model was developed to assess the effects of three key parameters: remote point mass (RPM), remote point distance (RPD), and wind load (WL). Sensitivity analysis revealed that wind load contributes 72.2% to the maximum stress and 70.1% to the peak deformation, indicating its dominant influence. RPM contributes 18.5% and 19.5%, while RPD has the least impact (9.3% and 10.4%, respectively). Notably, a nonlinear coupling effect was observed between RPM and RPD, which significantly amplifies structural stress and displacement, whereas WL acts independently. This study provides a quantitative framework for enhancing the structural reliability of wind-solar powered atmospheric water harvesting systems and supports their deployment in off-grid agricultural scenarios.
