Summary
Mechanical vibration significantly degrades solar photovoltaic (PV) wing performance on spacecraft. This study shows vibration reduces maximum output power by 5.53% and lowers the fill factor, impacting energy conversion efficiency.
Area of Science:
- Spacecraft engineering

Background:
- Photovoltaic (PV) power generation is crucial for spacecraft energy.
- Mechanical vibrations from uncertain factors and unbalanced forces degrade PV wing performance during on-orbit operations.
Purpose of the Study:
- To investigate the impact of mechanical vibration on the output characteristics of solar PV array systems.
- To analyze the dynamic response and electrical output of a three-segment solar panel under vibration.
Main Methods:
- Numerical simulation software was employed to model a three-segment solar panel.
- Dynamic response and electrical output characteristics under mechanical vibration were analyzed.
- Simulation model correctness was validated through partial experimental confirmation.
Main Results:
- A maximum output power reduction of 5.53% was observed.
- The fill factor declined from 0.8031 to 0.7587 under specific vibration conditions (10 N/m², 0.3754 Hz, 74.9871° deflection).
Conclusions:
- Mechanical vibration significantly decreases the maximum output power and fill factor of solar panels.
- Overall energy conversion efficiency of solar panels is notably reduced when operating under vibration conditions.

01:09Radiation Pressure: Problem Solving
339
The radiation pressure applied by an electromagnetic wave on a perfectly absorbing surface equals the energy density of the wave. The wave's momentum also gets transferred to the surface when an electromagnetic wave is entirely absorbed by it. The rate at which momentum is transmitted to an absorbing surface perpendicular to the propagation direction equals the force on the surface.
The average value of the rate of momentum transfer divided by the absorbing area represents the average force...

01:17Characteristics of Simple Harmonic Motion
12.8K
The key characteristic of the simple harmonic motion is that the acceleration of the system and, therefore, the net force are proportional to the displacement and act in the opposite direction to the displacement. Additionally, the period and frequency of a simple harmonic oscillator are independent of its amplitude. For example, diving boards move faster or slower based on their thickness. A stiff, thick diving board has a large force constant, which causes it to have a smaller period, while a...

01:19Shearing Stress
533
Shearing stress, denoted by the Greek letter tau (τ), is stress caused by forces acting transversely on an object. These forces create internal ones within the entity in the plane where the external forces are applied. The resultant of these internal forces is the shear in the section.
The average shearing stress can be calculated by dividing the shear by the area of the cross-section.

2.6K
In animal cells, the extracellular matrix allows cells within tissues to withstand external stresses and transmits signals from the outside of the cell to the inside. The extracellular matrix is extensive, and its composition varies between different types of tissues. For example, the reticular fibers and ground substance make up the ECM in loose connective tissue, while collagen and bone minerals make up the ECM of bone tissue.

01:08IR Spectrum Peak Splitting: Symmetric vs Asymmetric Vibrations
944
Identical bonds within a polyatomic group can stretch symmetrically (in-phase) or asymmetrically (out-of-phase). Similar to hydrogen bonding, these vibrations also influence the shape of the IR peak. Generally, asymmetric stretching frequencies are higher than symmetric stretching frequencies. For example, primary amines exhibit two distinct IR peaks between 3300–3500 cm−1 corresponding to the symmetric and asymmetric N-H stretching, while secondary amines exhibit a single...

01:10Residual Stresses in Circular Shafts
165
In materials that exhibit elastic and plastic behavior, known as elastoplastic materials, residual stresses can accumulate when these materials experience plastic deformation. This deformation arises from either high levels of shearing stress or significant strains. Residual stresses are internal stresses that persist within a material after removing the external force causing deformation. This phenomenon is demonstrated when observing the behavior of a shaft under torque; notably, the...
