Transmission_vibro

The program is designed to calculate the crankshaft of an internal combustion engine and the drive transmission of an electric generator to torsional oscillations and can be used in design and engineering work, as well as in teaching students "Design and calculation of internal combustion engines”. The program provides: calculation of frequencies and determination of vibration patterns of the eight mass dynamic system, analysis of vibration frequencies and search for resonant relationships, determination of the torque on the crank and amplitudes of its harmonic components with different motor indices, calculation of the angles of twisting angles and torque at different parts of the crankshaft based on the construction of amplitude-frequency characteristics, refinement of resonance frequencies with allowance for dissipation of vibration energy.

Artillery shell

The invention pertains to artillery shells fired from the barrel of a gun and stabilized in flight by rotation. The invention is directed to the creation of a self-lubricating artillery shell, which makes it possible to reduce the coefficient of friction from the introduction of the girdle into the rifling of the barrel, to reduce the temperature and the scoring. of the barrel

Device for forming products

The invention pertains to devices for forming large-sized composite products from composite materials or ceramics, for example, from aqueous slurries. The device for forming products comprises a matrix, a core and assemblies for their mutual coaxial installation and make-up. The device is provided with a disk diaphragm fixed to the matrix by means of a unit of a coaxial installation and an arch type beam that is fastened on its upper sides to the upper plane of the disk membrane and a vibrator with a working tip mounted coaxially with a core rigidly fixed to the beam, The tip abuts against the membrane at its central point. The end of the core is rigidly fixed in the centre of the lower plane of the disk membrane, and its outer surface is formed with longitudinal grooves, with the height h and the pitch s of the grooves being equal to 1/200 D, where D is the diameter of the core. The use of the device makes it possible to improve the quality of the products obtained by reducing the friction coefficient of the mixture (slip) used on the matrix and core walls.

Targeted flowmeter

The utility model pertains to measuring the volume of liquids by passing them through the measuring devices by a continuous flow, and pertains to a device for measuring the flow of liquid. The target flowmeter contains a target in the form of an axisymmetric cone-shaped body oriented by the base of the cone against the liquid flow, a rod, an elastic thin-walled tube and strain gauges, while an elastic thin-walled tube is placed in a power cap, the tube base is attached to the pipeline wall with the aid of a bellows moving along the hood, and the space between the tube and the hood is filled with an auxiliary liquid. The proposed solution makes it possible to increase the sensitivity of the target flowmeter when measuring the flow of viscous liquid in high-pressure pipelines.
