“…Hence, many novel types of low-pass filter using defected ground structures (DGSs) and compact microstrip resonating cell (CMRC) have been proposed by many researchers [1][2][3][4][5][6][7][8][9] in recent years. The variation of output intensity of LPFG is analyzed and the model of calculating acceleration is built.…”

“…The circuit, which occupies only 0.008 mm 2 core area, exhibited a maximum locking range of 7.5 GHz or 30.5% with a fixed varactor tuning. Electro-accelerometer based on MEMS has been demonstrated to have a small size and high sensitivity, but it is also sensitive to electromagnetic interference [4]. ABSTRACT: An accelerometer based on the strain and bend characteristics of long period fiber grating (LPFG), which fabricated in Accelerometer is one of the most important transducer applied in mechanism, vehicle, bridge, aeronautics, and astronautics and military [1,2].…”

time delay of individual stages according to the tuning voltage variation. Finally, a source follower buffer stage is used for matching purpose in the measurement. MEASUREMENT RESULTSThe RO ILFD was fabricated in a commercial 0.13 lm Si RFCMOS technology. Figure 3 shows the layout and chip photo of the fabricated circuit. The total chip size including DC and RF pads is 0.52 mm Â 0.46 mm, whereas the core area occupies only 0.1 mm Â 0.08 mm. On-wafer probing was carried out with all the losses from the probes, cables, connectors, and bias-T carefully calibrated and accounted for.At the absence of the input signal, the free-running frequency of the ILFD was varied from 8.85 to 9.67 GHz with the varactor bias tuning of 0-1.5 V. The circuit consumes DC power of 13 mW with 1.5 V supply voltage including the buffer. The locking was achieved with a signal injection from a HP 8565E signal generator. The free-running and locked output spectra are compared in Figure 4, showing a significantly improved phase noise with the signal injection, indicating proper signal locking achieved. The measured input sensitivity curves at two varactor tuning voltages (V tune ¼ 0 V and 1.5 V) are shown in Figure 5. The plot shows a locking range of 7.5 GHz (20.8-28.3 GHz, 30.5%) with V tune ¼ 1.5 V at the input power of 0 dBm. A similar locking range of 6.7 GHz (24.1-30.8 GHz, 24.4%) was achieved with V tune ¼ 0 V, leading to the total operating range of 10 GHz (20.8-30.8 GHz, 38.8%). The performance of the present ILFD is compared with previously published divide-by-3 ILFDs in Table 1. To the authors' best knowledge, the locking range of 30.5% is the largest for any reported divide-by-3 ILFD operating beyond 10 GHz including the LC ILFDs. Further, the chip area of the present design is only a fraction of those with the LC ILFDs when the core area is considered, a critical advantage as the area cost keeps rising. 4.

“…For example, for munition launching, the acceleration can easily exceed 10 kg. Capacitive accelerometers can be used for high-g applications in the 1-20 kg range with better temperature stability (Beliveau et al 1999, Davis et al 2004, Stauffer 2006, Stewart et al 2004. The strong radiation must be considered in all space missions (Brown 2003, Cass 2001.…”

“…Such parts or systems working in the harsh inertial environments must strictly test for design qualification, survivability testing, and calibration. For specimens with variable weights and sizes, now available experimental technologies include pendulum striker, drop machines, Hopkinson pressure bar, free fall drop test devices, air gun, rail gun, explosion near field simulation, and warhead penetration [2][3][4][5][6][7][8][9][10][11][12]. e inspiration of this paper comes from the fact that a compressed air cannon can produce instantaneous and powerful air jets that can be used to drive the tested object to achieve a high initial collision velocity.…”

According to the technical requirements of harsh shock environment test, this paper presents the study on the pneumatic vertical test technology with large load and high-g value. The inspiration of this paper comes from the fact that a compressed air cannon can produce instantaneous and powerful air jets that can be used to drive the tested object to achieve a high initial collision velocity. Then, the principle of shock test technology based on an air cannon and an impact cylinder was put forward, and the idea gas mechanics model was established to theoretically analyze the laws that how the parameters of the air cannon and cylinder influence the initial impact velocities. The test system was built, and the test research was carried out. When the air cannon pressure is 0.5 MPa and 0.65 MPa, respectively, under no-load, the impact acceleration measured is 1990 g (pulse width, 1.26 ms) (1g = 9.8 m/s2) and 4429 g (pulse width, 1.20 ms). It preliminarily validated the effectiveness and feasibility.
