| Abstract |
Background. The simulation modeling is an integral part of process of development of all sensors working in rigid conditions of operation. Methods of a simulation modeling allow to obtain necessary information on the processes proceeding in sensors at a preliminary expensive stage of prototyping without resorting to field tests. The purpose of the presented simulation modeling is definition of influence of impact of external factors on operability of a high-temperature piezoelectric transducer of pressure which JSC «NIIFI», for confirmation of a regularity of the chosen design decisions develops.
Materials and methods. As a research technique the simulation modeling at which the studied object (sensor) is replaced with its model with which experiments for the purpose of obtaining information on this object are made was used. In an experiment the specialized software of Solidworks allowing to avoid the expensive and long-lived cycles «projection–manufacture–test» was applied.
Results. As a result of model operation of influence of external factors on operability of the sensor the maximal tension arising at impact of static pressures on a sensor membrane is determined; the maximal tension at impact of sinusoidal vibration and mechanical blow; epyura of distribution of temperature profiles at influence of temperature of 3000 °C within 6 seconds are constructed.
Conclusions. The put design solutions of the sensor of fast-live pressure provide resistance of the sensor to destabilizing factors, temperature, static pressure, high levels of vibration and shock loads.
