Calculation of reaction force of photovoltaic support column

How do you calculate reaction forces?

To calculate reaction forces, we first need to know whether the structure is statically determinate or indeterminate. For statically determinate structures, the reaction forces can be calculated by the 3 Equilibrium equations. ∑ H = 0: The sum of all horizontal external loads and reaction forces equals 0.

How to evaluate the dynamic response of tracking photovoltaic support system?

To effectively evaluate the dynamic response of tracking photovoltaic support system, it is essential to perform a tracking photovoltaic support systematic modal analysis that enables a comprehensive understanding of the inherent dynamic characteristics of the structures.

How does wind force affect solar panel structure stability?

1.08 . The design of solar panel supporting structure is done and the effects of wind force on its structure stability is analysed. Due to the wind force, a reaction force is experienced on the structure and the structure will retain its stable state, only if this reaction force is compensated by the force due the self-weight of the structure.

How do you find the vertical reaction force at support B?

We need to solve another equation in order to find B y (the vertical reaction force at support B). 2. Sum of Horizontal Forces (ΣFy = 0) Sum the forces in the y (vertical) direction and let the sum equal zero. Remember to include all forces including reactions and normal loads such as point loads.

How stiff is a tracking photovoltaic support system?

Because the support structure of the tracking photovoltaic support system has a long extension length and the components are D-shaped hollow steel pipes, the overall stiffness of the structure was found to be low, and the first three natural frequencies were between 2.934 and 4.921.

How many pillars does a photovoltaic support system have?

The tracking photovoltaic support system consisted of 10 pillars (including 1 drive pillar), one axis bar, 11 shaft rods, 52 photovoltaic panels, 54 photovoltaic support purlins, driving devices and 9 sliding bearings, and also includes the connection between the frame and its axis bar. Total length was 60.49 m, as shown in Fig. 8.
