The novel diesel engine test-bed vibration-isolation and vibration-reduction system comprises a concrete foundation block, a vibration reducing device, a base plate, a support, a sliding adjusting block, and a vibration isolating block, wherein the support is fixed on the base plate, the sliding adjusting block which can slide up and down along the support is arranged on the support, the vibration isolating block is arranged on the sliding adjusting block, the base plate is fixed on the concrete foundation block, and the bottom face of the concrete foundation block is provided with the vibration reducing device. Vibration energy gained through vibration reduction by a rubber block is re-transmitted to the base plate of the support, transmitted to a big iron casting base plate, transmitted to the concrete foundation block with high mass, and re-transmitted to a steel spring vibration-isolation gasket, after the vibration energy is absorbed by a steel spring in an elastic mode, the frequency that the vibration energy is transmitted to a base is lowered to be below hertz. Therefore, vibration of surrounding testing environments is improved, normal working requirements of various instruments and meters are met, and performances are reliable.
Description
Technical field
Of the present utility modelly be specifically related to a kind of novel diesel-engine tester frame vibration isolation and damping system.
Background technique
Traditional diesel-engine tester frame basis main feature is: adopt the concrete foundation vibration damping of big quality, adopt vibration isolate ditch or vibration isolation bed course to prevent to vibrate and pass to around the basis.It all is the material that is fit to that the vibration isolation bed course can adopt husky carbon slag fiberglass packing of multiple material proper viscosity etc.The tradition foundation cost is low, and the effect of vibration damping and vibration isolation is relatively poor, constructional difficulties, pipe line arrangement difficulty.
The model utility content
For solving the problems of the technologies described above, the utility model provides a kind of novel diesel-engine tester frame vibration isolation and damping system.
The technical solution adopted in the utility model is as follows:
A kind of novel diesel-engine tester frame vibration isolation and damping system, comprise concrete foundation block, damping device, base plate, support, slidable adjustment piece, shock insulation piece, be fixed with support on the described base plate, support is provided with the slidable adjustment piece that can slide up and down along support, described slidable adjustment piece is provided with the shock insulation piece, described base plate is fixed on the concrete foundation block, and described concrete foundation block bottom surface is provided with damping device.
Described shock insulation piece is the rubber vibration isolation piece, and its profile is made of the block rubber that is subjected to section and free surface, is subjected to section mutually bonding with sheet metal.
Described support is fixed on the base plate by the support base plate.
Described rubber vibration isolation piece supports motor.
Described baseboard material is a cast iron.
What described damping device adopted is steel spring vibration isolator group.
The beneficial effects of the utility model are:
Adopt basement to arrange the test-bed basis, the concrete of big quality is adopted on the basis, and vibration damping mainly reduces the amplitude on basis by the big quality of concrete foundation.And damping vibration attenuation is mainly by additional suitable rubber damping on the steel spring vibration damper, to reach the purpose that reduces basal amplitude.This structure adopts basement to arrange the civil engineering structure form of basis seat, basis seat easy construction, and the space is big around the basis, is convenient to arrange various pipelines.By adjusting the quality of concrete foundation block, can control the amplitude of table top, satisfy the high precision measurement requirement.
Mounting bracket slidable adjustment piece on test-bed base plate engine support is provided with suitable rubber vibration isolation piece on support slidable adjustment piece.The profile of rubber vibration isolation piece is made of the block rubber that is subjected to section and free surface, is subjected to section mutually bonding with metal, sees that figure is called the stand under load area, can free expansion.When being subjected to section and metal adhesion, when load by compression, rubber laterally expands, but suffered restraints by the distortion of section.Be subjected to section big more like this, the free surface is more little, and the rigidity of rubber parts is big more.This physical property of block rubber response lag and stress after loading present and return the hysteresis position, can be in loaded cycle the material internal consumed energy, thereby the kinetic energy of the engine luggine that dissipated plays the effect of vibration damping.
Vibrational energy by the block rubber vibration damping passes to the support base plate again, pass to the big base plate of cast iron, the concrete foundation block that passes to big quality passes to the steel spring vibration isolator again, the frequency of passing to the basis seat after the elasticity absorption through steel spring has been reduced to below the hertz, the vibration of test surrounding environment improves, satisfy the proper functioning requirement of various instrument and apparatus, reliable performance.
