acceleration

Реалізована процедура використання алгоритму класичного фільтра Калмана для оцінки параметрів руху об’єкта, що маневрує. Застосування фільтра Калмана мотивовано необхідністю мінімізувати дисперсію оцінки вектора випадкового процесу. Результати оцінки параметрів руху обробляють згладжуючим алгоритмом Рауч–Тюнга– Штрібеля також з метою мінімізації дисперсії. Алгоритми Калмана та Рауча–Тюнга– Штрібеля можна застосовувати для використання в оцінці параметрів руху автомобіля, повітряного судна, бойового снаряду.

The existing acceleration measuring methods are analyzed in the article. An overview of modern research on this topic is also provided. A new method of measuring acceleration in the form of an electrical circuit using a stable frequency generator is developed. Among the already known methods, the following three groups are highlighted in the analysis: methods based on compensatory accelerometers with discrete output; methods based on accelerometers with the analog-to-digital converter; measurement techniques, which use mounted elements.

This work concerns problems connected with race car's behavior permitted to traffic motion on dry asphalt surface during braking and rapid acceleration . The characteristics of the vehicle is presented with particular reference to type of tires. Environmental characteristics and road surface were made. The result of the research and analysis are kinematic characteristics of the particular features of the vehicle enabling assessment the probable risk both for diver and other road users.

In the paper, VHDL-AMS model of microaccelerometer with sigma-delta control for computer-aided design has been developed. The created model has made possible the simulation of dynamic characteristics of the integrated capacitive microaccelerometer, signal processing and digitizing, simulation of force feedback control using sigma-delta technique on the applied force of acceleration and also to perform the analysis of the device at the behavioral level of computer-aided design.

The article presents the results of experimental studies of the process of intense acceleration, passing through the barrier and the vehicle brakes adapted for the transport of persons using two speed ranges passing through the barrier. Tests were conducted on dry roads made of cobblestones. Performed experimental studies, which aim was to determine the acceleration in each axis while passing through the obstacle.

Simulation model of the mechanical component of the fully differential capacitive MEMS accelerometer has been developed using MATLAB/Simulink environment. The model allows to simulate movement of the proof mass, capacitance changes of the sense capacitors of the sensitive element, sensitivity of the sensor depending on the applied force of acceleration, and to perform the transient analysis of the integrated device at the system level of computeraided design.

The essence of levers of regulation and increased efficiency of investment activities in the region  is  determinated  in  terms  of  regional  economy,  management,  theory  and  practice  of investment.  Classification  of  levers  of  regional  investment  activities  regulation  is  proposed.
