enviClone Photovoltaic PV Module Solar Panel Wind Resistance Dynamic Mechanical Load Test Machine

The PV modules Dynamic Mechanical Load (DML) Test Machine simulates the dynamic load with the pneumatic cylinders and suction cups. Each pneumatic cylinder drives one suction cup, and each cylinder rod is equipped with one tension pressure sensor. Each pneumatic cylinder is a separate control module. Periodic load stress test is performed on the Photovoltaic (PV) Modules’ surface, and PV Modules can be installed according to different requirements. The system also has the ability to monitor the curvature of the PV Module’s center points in real time.

The Dynamic Mechanical Loading Testing Equipment is used to test wind resistance or impact capacity performance of solar energy pv modules as per international test standard IEC TS 62782

FeaturesLoad application method:
the cylinder drives the suction cup to press and suck;
Mechanical load material and structure:Made of aluminum alloy hot extruded profiles, movable aluminum alloy frame, each screw connection needs to have spring washers to prevent loosening;
A new tracking base is added to the traditional base for the installation of the tracking bracket. The tracking base has a short span and multiple supports to ensure stability during the test process;
The test platform is 800mm from the ground by default and can be adjusted to 760 or 780mm through the guide rail;
Each suction cup structure includes a cylinder, suction cup, pull pressure gauge, etc., making control more convenient;
The pressure of each cylinder can be controlled individually to achieve different load values in different areas of the component;
Industrial computer control and recording, large data storage capacity;
Pressure, tension, holding time, number of cycles, cycle frequency, and current size can be preset;
Pressurization time can be set;
