The Effect of Hydraulic Dynamic Damping

February 7, 2017 · Posted in Uncategorised · Comment 

Dynamic damping, as the name suggests, is to improve the dynamic performance and set the damping, usually only in the dynamic (transient) when it plays a role, at least there are three roles: 1, shock absorption; 2, delay actuators time; Controlled interstage dynamic pressure feedback.

Steel structure drilling machine

1, such as the pilot relief valve main valve spool cavity set dynamic damping, can reduce the dynamic process of vibration, the greater the vibration, the stronger the damping effect, but in a small range of vibration, the damping effect is almost no. Set the damping on the spool off time greater  steel straightening machine impact should be taken into account shock absorption and response time.
2, such as the pilot reversing valve of the main commutation stage, set the damping can make the commutation gentle, but does not affect the steady-state performance, the damping and spring cavity constitute a first-order inertia, the turning frequency is generally higher than the spool second- Of the natural frequency, determines the frequency response of the valve. In fact, is the import and export of throttle valve speed control model.
3, the direct pressure comparison pilot relief valve pilot level, set the dynamic steel beam fabrication pressure damping, one is to improve the dynamic process, increase the speed of damping coefficient, the second is to constitute the level of dynamic pressure feedback, feedback to achieve a form.

The future mission of the Earth Science Lidar

January 20, 2017 · Posted in Uncategorised · Comment 

1 Ice Sheet, Cloud and Land Altitude Monitoring Satellite-2 Mission (ICESat-2) ICESat-2 is the ICESat follow-up mission. ICESat was launched in January 2003 and ended in February 2010. ICESat-2 will provide high-quality terrain measurement data to assess the changes in ice volume, decisive ice melting to sea-level rise. ICESat-2 on the load name for the Advanced Terrain Measurement Laser Altitude System (AdvancedTopographicLaserAltimeterSystem best cnc machines, ATLAS). The original ATLAS vision is an egg-beam laser height system that follows the GLAS concept with low repetition (50 Hz), high energy (pulse energy 50 mJ), and short pulse width (about 6 ns). In mid-2009, ATLAS was re-envisioned. At the moment the idea of ​​using non-scanning 6 beam system, the beam arrangement is 3 × 2, using micro-pulse photon counting system, as shown in Figure 1. Figure 1 (a) NASES second-generation Earth orbit multi-beam laser altimeter ICESat-2 shows the attempt; (b) The laser uses high repetition frequency (10kHz) welding gantry, medium energy (single pulse energy about 900μJ), short pulse width (<1.5ns). Hamamatsu Model 7600-16M photomultiplier was used as the detector. Laser wavelength 1064nm frequency multiplier of 532nm, the reason is the lack of space for the use of long-lived near-infrared single photon detector. Figure 2 (left) space measurement point of view; (on the right) using the two HITRAN2004 calculated near the 1570nm wavelength near CO2 transmittance results; (left) at the moment the choice of 1572 metal sheet punching machine.33nmCO2 receive line and wavelength sampling strategy; Weighted function of calculation 3.2 Automatic Monitoring of CO2 Emissions at Night, Day and Season (ASCENDS) ASCENDS intends to be the first space-based laser spectroscopy instrument that can be thought of as weather and hydrography to monitor changes in aerosols and clouds, and to monitor changes in sea-color for open-ocean biogeochemistry.

 

ASCENDS using laser absorption spectroscopy to measure the global atmosphere of carbon dioxide spatial distribution of precision to 1 ~ 2ppm, measuring global land and sea carbon dioxide source and sink spatial resolution of 1 degree, the data update rate once a month, can supply On the continuous measurement of the sea without clouds, in the low sun angle and night can do. GSC (GoddardSpaceFlightCenter) uses a pulsed lidar as a candidate for ASCENDS, as shown in Figure 3. The scheme uses a parametric erbium-doped fiber amplifier to amplify the 1.57μm spectral range of the near-far wavelength, which is used to measure the atmospheric carbon dioxide. The accuracy of the initial path measurement is less than 1%. Using a dual-band laser pulse laser absorption spectrometer and differential path to receive laser radar technology. Figure 3 space laser radar performance and 500km orbital altitude radar mold mounted map 3.3 LIDAR Profiles Description of the Measurement Mission (LIST) LIST intends to complete the measurement requirements of jade into the cage cover, life of 3 years cnc punch, 400km orbital height, 5km imaging banner width, the basic rationale shown in Figure 4. 3.4 Earth Gravity Field Measurements and Weather Attempts (GRACE-FO and GRACE-2) GRACE-2 system is estimated to launch in 2025, the system uses a laser ranging system to get a higher accuracy. The GRACE-FO system was estimated to be launched in 2016 to verify the feasibility of the laser ranging system used in the GRACE-2 system. The performance objectives of single-frequency lasers in GRACE-FO are shown in Table 2.

Clutch in the precision punch in what role Punching clutch is an important part of precision punching machine

Clutch in the precision punch in what role Punching clutch is an important part of precision punching machine Busbar Processing Machine. It is installed between the flywheel and the crankshaft of the punch press. The clutch and the brake are synchronized during the operation pipe welding machine. That is, the clutch is actuated, the brake is released, the clutch is divided. Action, brake lock. The clutch shaft comprises a clutch main body, a clutch oblique key, a clutch lever and a gland, wherein the rotary shaft of the clutch oblique key and the clutch lever are respectively installed in the shaft hole of the clutch main body and the gland angle shearing machine, The clutch hook oblique key of the hook-shaped lever and the clutch lever on the short arm position in the clutch body of the bending column wall spring hole is equipped with compression spring, the clutch is running principle: When the clutch oblique keys under the action of the spring Into the corresponding wedge keyway of the drive flywheel to effect drive engagement. In actual operation, the clutch control brake by opening and closing to determine the stroke of the slider, the brake release, the punch of the cam mechanism will work, the slider down, when any point brake tightened, the cam-controlled The axis will get an empty trip, the slider picks up.
