Background. Simulation modeling is an integral part of the development process for all sensors operating in harsh environments. The methods of simulation modeling make it possible to obtain the necessary information about the processes occurring in the sensors at the stage of modeling, without resorting to costly in-situ tests. The purpose of the presented simulation is to determine the impact of external factors on the performance of the strain gauge pressure sensor, to confirm the correctness of the selected design solutions. Materials and methods. As a method of research, simulation modeling was used, in which the sensor under study is replaced by its model, with which experiments are conducted in order to obtain information about this object. Specialized Solidworks software was used in the experiment to avoid costly and time-consuming «design-build-test» cycles. Results. As a result of modeling the influence of external factors on the performance of the sensor the maximum stresses arising under the influence of sinusoidal vibration are determined, the resonance frequencies are identified. The structural solutions laid down by the pressure sensor provide the sensor resistance to destabilizing factors.
