Damping-Free Flexible Horizontal Single-Axis Tracking Bracket: Structural Innovation & Industry Breakthrough (Issue 11)

Damping-Free Flexible Horizontal Single-Axis Tracking Bracket Technical Analysis

Tianjin AQINI New Energy Technology Co., Ltd. has been deeply engaged in the PV bracket field for 15 years, with core R&D led by the founder. We break away from the traditional design approach used throughout the industry, adopting a completely new structural route different from mainstream products, launching the damping-free flexible horizontal single-axis tracking bracket, fundamentally overcoming the inherent structural defects, durability shortcomings and various industry common problems of current PV tracking brackets.

Structural Dilemma of Traditional Tracking Brackets

Current mainstream horizontal single-axis tracking brackets generally use the damper + torque tube structural scheme, which exposes many unavoidable problems in actual operation:

• Damper Aging Failure — As a wearing part, dampers degrade year by year under outdoor extreme temperatures, sand and UV. After 3-5 years damping effect drops significantly, causing severe resonance under high wind conditions
• Torque Tube Fatigue Fracture — Torque tubes endure alternating torsional stress long-term, fatigue cracks easily form at welds, and in extreme cases fracture, causing entire string module damage
• High Slewing Drive Maintenance Cost — Traditional slewing drives require regular lubrication and seal replacement, with O&M costs growing linearly with plant scale
• Poor Snow Load Adaptability — Under heavy snow, traditional bracket tilt adjustment is limited, snow cannot slide off naturally, causing module micro-cracks or even bracket deformation

Core Innovation of Damping-Free Flexible Structure

The damping-free flexible horizontal single-axis tracking bracket completely abandons the traditional damper solution, adopting a new structural route of flexible cable network + single slewing drive. Core innovations include:

1. Flexible Cable Network Load-Bearing System

Drawing on mature structural mechanics principles of suspension and cable-stayed bridges, high-strength low-relaxation prestressed steel strands serve as main load-bearing components,combined with patented anchor system to form a flexible cable network load-bearing system. This system has natural self-balancing characteristics, with wind loads evenly distributed to each anchor point through the cable network, fundamentally eliminating resonance risk.

2. Single Slewing Drive Solution

Using large-array single slewing drive, one drive unit can drive bracket arrays hundreds of meters long, significantly reducing the number of drive units. The slewing drive uses dual-seal structure, internal cleanliness is effectively guaranteed, combined with self-lubricating bearings, key components require no regular lubrication, achieving truly maintenance-free operation.

3. Damping-Free Design Philosophy

Damping-free design is not simply removing the damper, but through structural mechanics optimization, enabling the system to remain in stable equilibrium under all working conditions. The prestressed tensioning of the flexible cable network provides sufficient system stiffness while retaining moderate flexible deformation capacity, able to absorb wind load impact energy, achieving "overcoming hardness with flexibility".

Core Comparison with Traditional Products

Extreme Environment Adaptability

The damping-free flexible horizontal single-axis tracking bracket has been verified by century-equivalent weathering test standards, capable of stable operation in various extreme environments:

• High Wind Environment — Intelligent high wind stow strategy, automatically adjusts to protective angle when wind speed exceeds threshold, flexible cable network can withstand winds above level 12
• Snow Environment — After heavy snow alert, adjusts to maximum tilt angle, snow slides off naturally, avoiding module micro-cracks
• Desert Environment — Dual-seal drive structure effectively blocks sand intrusion, self-lubricating bearings require no regular maintenance
• Coastal High-Humidity Environment — High-quality materials and coating technology, meeting international standards and corrosion resistance requirements, 100% salt spray test pass rate

Production Capacity & Delivery Assurance

Tianjin AQINI New Energy relies on the top-tier industrial cluster in Daqiuzhuang, Tianjin for mass production outsourcing. The flexible bracket production base can meet approximately 5GW of flexible bracket supply capacity. We do not blindly pursue heavy asset expansion and large-scale personnel structure, always adhering to core technology self-research, with the globally unique century-equivalent weathering test standard, 20-year automotive-grade overall warranty, and ultra-large-scale production capacity as core foundations.
