“…Frequency fB indicates the resonant frequency. It is clear from the figure that at a lower frequency fA, but also at a higher frequency fC, the amplitude is significantly lower than at the resonant frequency fB, where the amplitude we do not even see [5][6][7].…”

This paper deals with modal analysis through 3 different approaches, namely: analytically, numerically and experimentally. The investigated mechanical structure in this case will be a beam, which is characterized by three parameters, one of which is significantly larger than the other two. The beam is a structural element designed to transmit forces, mostly external ones. Modal analysis of the beam will be performed in 2 versions of its fixation, as a free structure and a one-sided embedded fixation. Modal parameters obtained by 3 different approaches will be compared with each other, which will determine whether the method of calculation was chosen correctly or whether the experiment was performed correctly.

“…Angle sensors are widely used in various applications where precise angle measurements are required, including automobiles [ 1 ], aviation servo systems [ 2 ], and industrial robots [ 3 ]. Depending on the underlying angle measurement method, angle sensors can be divided into contact angle sensors [ 4 ] and non-contact angle sensors [ 5 , 6 , 7 ]. Contact angle sensors are mainly the potentiometer-type angle sensors [ 8 ], where the presence of friction during measurements makes these sensors more prone to wear, electrical noise, short life, etc.…”

This paper presents the design and the non-linearity optimization of a new vertical non-contact angle sensor based on the electromagnetic induction principle. The proposed sensor consists of a stator part (with one solenoidal excitation coil and three sinusoidal receiver coils) and a rotor part (with six rectangular metal sheets). The receiver coil was designed based on the differential principle, which eliminates the effect of the excitation coil on the induced voltage of the receiver coil, and essentially decouples the excitation field from the eddy current field. Moreover, the induced voltages in the three receiver coils are three-phase sinusoidal signals with a phase difference of 10°, which are linearized by CLARK transformation. To minimize the sensor non-linearity, the Plackett–Burman technique was used, which identified the stator radius and the rotor blade thickness as the key factors affecting the sensor linearity. Then, the particle swarm algorithm with decreasing inertia weights was utilized to optimize the sensor linearity. A sensor prototype was made and tested in the laboratory, where the experimental results showed that the sensor non-linearity was only 0.648% and 0.645% in the clockwise and counterclockwise directions, respectively. Notably, the non-linearity of the sensor was less than −0.696% at different speeds.

The inclination angle is an important factor for slope deformation monitoring. This paper introduces a self-powered pendulum inclination sensor (PI-TENG) based on triboelectric nanogenerator, which can effectively monitor slope deformation. PI-TENG adopts raster-sliding mode as the main structure. The fabricated PI-TENG, based on a raster-sliding working mode, using the linear relationship between the rotation angle of the monitoring object and the number of output pulses to establish an intuitive rotation signal mapping, which can realize self-powered monitoring of the rotation direction and angle not being affected by the environment (such as temperature and humidity). The corresponding minimum resolution of PI-TENG is 3° and can be further improved by increasing the number of Nylon grids on the stator. Importantly, the sensor has a simple structure and low price, and can realize self-powered monitoring without additional power supply. This work provides new ideas for monitoring slope deformation and early warning of landslides.
