Stabilization system for sensors on moving platforms

ActiveUS20110175604A1Improve mass balanceSmall biasAcceleration measurementFrequency analysisRotational stabilityAir bearing
A stabilized field sensor apparatus collects field data, in particular magnetic field data, with reduced motion noise. The apparatus includes a tear drop shaped housing, a tow frame in the housing, a plurality of vibration isolating dampers spaced around the frame, a base assembly mounted to the dampers, a support pedestal having a bottom end fixed to the base assembly and an upper free end, a single spherical air bearing connected to the upper free end of the pedestal, an instrument platform with a lower hollow funnel having an upper inside apex supported on the air bearing for a one point support, principal and secondary gyro stabilizers for maintaining pivotal and rotational stability, and at least one field sensor mounted to the instrument platform for collecting the field data while being stabilized against motion noise including vibration, pivoting and rotation from the base assembly, from the tow frame and from the housing. Stabilization of the instrument platform is enhanced by preserving accurate balance through a dynamic balancing system whereby small masses are moved under computer control to maintain the center of mass of the instrument platform at the center of rotation of the spherical air bearing. The dynamic stabilization process is made more precise by actively vibrating the instrument platform by a set of linear vibrators.

Encoder cushioning structure

An encoder cushioning structure is installed between an encoder and a motor support and is characterized in that the encoder cushioning structure comprises a cushioning ring elastic sheet and a cushioning ring outer casing, the cushioning ring elastic sheet is a four-claw elastic sheet with four extension ends which are evenly distributed at the periphery and extend from the center, and tail ends of the four extension ends are fixedly installed on an inner edge of the cushioning ring outer casing through screws. Encoder fixing holes fixed with the encoder are further arranged on the cushioning ring elastic sheet. The encoder cushioning structure improves an elastic sheet structure in the cushioning structure, the four extension ends can averagely disperse vibration ranges, the four extension ends are divided into eight screw fixing positions to further promote cushioning and damping effects, simultaneously the extension ends of the four-claw elastic sheets have hyperbolic-curve wavy fluctuation and have better fluctuation cushioning effects for facing strong vibration than those of straight rib sheets, and the encoder cushioning structure is good in whole cushioning effect and even in vibration dispersion, guarantees good mechanical behavior, and is not easy to bend and deform.

Vacuum operating platform with damping mechanism

The invention discloses a vacuum operating platform with a damping mechanism, wherein the vacuum operating platform is fixedly connected with a sealing flange through a vacuum chamber shell; the sealing flange is fixedly connected with a damping flange; an upper corrugated pipe is fixedly connected between a platform supporting plate and the damping flange; and a lower corrugated pipe is fixedly connected between the sealing flange and the platform supporting plate. When vibration is generated, the vacuum chamber shell transfers the vibration to the sealing flange; the sealing flange directly transfers the vibration to the lower corrugated pipe; meanwhile, the vibration of the sealing flange is transferred to the damping flange through an auxiliary supporting part and then transferred to the upper corrugated pipe; the damping flange can be regulated along the axial direction of the auxiliary supporting part so as to regulate deformation of the upper corrugated pipe and the lower corrugated pipe; and therefore, the vibration force of the upper corrugated pipe transferring to the platform supporting plate is opposite to the vibration force of the lower corrugated pipe transferring to the platform supporting plate. As a result, the vibration of the platform supporting plate is effectively reduced.

Systems and Methods for Enclosing Instrument Encasing Systems

Improved instrument encasing systems may solve a variety of problems associated with existing systems. In one aspect, an improved instrument encasing system may include a suspension bracket and back plate that enable tool-less mounting and/or disassembly and/or security in mobile installations. Optionally, the system suspension bracket also may provide a template for easy alignment and selection of a mounting position and/or installation thereto. In some embodiments, the back plate may be temporarily reduced in diameter to enable quick and easy access to instruments mounted on an inner housing, or for access to the dial face for personalization. In another aspect, an inner housing of the instrument encasing system may provide one or more spring blades that receive instrument mounting sub-assemblies that provide for easy mounting and replacement of instruments. Optionally, stabilization weights also may be provided in the inner housing to absorb vibrations and increase the overall weight and stability of the housing, enabling lighter materials to be used in the manufacture of other components. In some embodiments, a Physical Vapor Deposition coating may be applied to an outer housing to provide various functional and/or aesthetic qualities.

Vibration reduction and impact resistance method for spaceflight sensor

The invention relates to a vibration reduction and impact resistance method for a spaceflight sensor. The vibration reduction and impact resistance method comprises the steps of: analyzing a vibration source; determining the range of the inherent frequency f of a system consisting of vibration reduction and impact resistance materials and a sensor; setting the amplification factor Q for generating resonance of the sensor and the input excitation at the inherent frequency f part of the sensor; determining the damping coefficient Zeta of the vibration reduction and impact resistance materials; estimating the rigidity k of the vibration reduction and impact resistance materials through finite element analysis software, and determining the shape, the number and the arrangement form of the vibration reduction and impact resistance materials; and the like. The vibration reduction and impact resistance method has the advantages that the vibration reduction and impact resistance compatibility of the spaceflight sensor under the mechanical environment is simultaneously considered, firstly, the vibration reduction requirement is met, the proper damping of the vibration reduction and impact resistance materials is selected so that the amplification factor is in a controllable range, next, the inherent frequency of the whole system is reduced to the maximum degree, the transmissibility of the system is reduced for meeting the impact resistance requirement, the vibration reduction and the impact resistance of the spaceflight sensor are effectively realized, and the performance stability of products in spaceflight mechanical environment is ensured.
