Ensuring Structural Rigidity and Wind Resistance Stability in the Ultra-Long Single-Row Layout of Mukunping's Ruimo Single-Axis Tracking Mount
Publish Time: 2026-02-12
In the construction of large-scale ground-mounted photovoltaic power plants, improving power generation efficiency per unit area and reducing system costs are core objectives. Mukunping's Ruimo single-axis tracking mount, with its flexible compatibility with ultra-long single-row photovoltaic modules ranging from 1×10 to 1×78, significantly reduces the number of support columns and land occupation, optimizing array layout density. However, with the increase in single-row length, problems such as increased structural flexibility, increased risk of wind-induced vibration, and exacerbated torsional instability also arise.
1. High-Strength Main Beam and Torsional Section Design
The core of the Ruimo mount lies in its customized high-strength main beam system. For extreme length configurations such as 1×78, the main beam adopts a closed-type or stiffened C-shaped aluminum alloy/galvanized steel section, possessing high moment of inertia and torsional stiffness. Transverse baffles and longitudinal stiffening ribs are added inside the section to effectively suppress local buckling and overall torsion under long-distance stress. Meanwhile, the main beam adopts a continuous, full-length design or high-precision flange connection, avoiding the stiffness reduction caused by traditional multi-segment splicing. This integrated force path ensures that even under strong winds, the entire row of components can maintain synchronous movement, avoiding component microcracks or connection failures due to local deformation.
2. Modular Support and Distributed Column Layout
To balance the ultra-long span with structural stability, Ruimo adopts a "distributed column + elastic support" strategy. The column spacing is dynamically optimized according to local wind pressure, snow load, and soil conditions, typically controlled between 6 and 9 meters, and adapts to different terrains through adjustable bases. Each column integrates a universal hinge bearing or flexible rotating shaft mechanism at its top, allowing the support to rotate smoothly with the solar azimuth angle and dissipate energy through slight swaying during strong winds, reducing the risk of resonance. In addition, diagonal tie rods or X-shaped cross supports are set at key nodes to form a spatial truss effect, significantly improving the overall resistance to lateral wind loads.
3. Wind Tunnel Verification and Aerodynamic Optimization
The Ruimo support system has been verified through both CFD simulation and wind tunnel testing. To address the "wake interference" and "vortex-induced vibration" easily caused by ultra-long single-row components, engineers aerodynamically optimized the component arrangement tilt angle, the shape of the windward side of the main beam, and the gap ratio. For example, in high-wind-speed areas, a low initial tilt angle of 0°–15° is recommended to reduce the windward area; simultaneously, guide holes are opened on the back of the main beam to disrupt the formation conditions of the Karman vortex street. These measures effectively reduce the wind load factor by 15%–25%, significantly improving operational safety under extreme weather conditions.
4. High-Precision Manufacturing and Rapid On-Site Assembly
Achieving structural performance relies heavily on manufacturing and installation precision. All Ruimo main beams and connectors are manufactured using CNC stamping and laser cutting processes, with tolerances controlled within ±0.5mm, ensuring no cumulative error after installation of the ultra-long component array. On-site installation employs a "pre-assembly + plug-in" method, significantly shortening the construction cycle while ensuring uniform stress distribution at each connection node, avoiding stress concentration caused by assembly deviations. With the aid of specialized torque tools, the pre-tightening force of all bolts is precisely controllable, further enhancing overall rigidity.
In summary, the Ruimo single-axis tracking bracket from Mukunping utilizes four pillars—high-strength main beams, intelligent support layout, aerodynamic optimization, and precision manufacturing—to support the installation of ultra-long single-row modules ranging from 1×10 to 1×78, while constructing a highly efficient, reliable, and wind-resistant structural system. This design not only meets the demands of high-irradiance regions for high-density, high-power generation but also provides a solid guarantee for the long-term safe operation of photovoltaic power plants in complex climatic environments.
