Краткое описание

A study of thermodynamics of multicomponent strain-gauge balance was carried out and measures were proposed to reduce its temperature errors due to the nonstationary spatial gradients of temperature. The balance thermal dynamic model based on the method of electric thermal analogy was developed and experimentally tested. A method was proposed for taking into account the variations of the zero reading of strain-gauge balance during the experiment.

Ключевые слова: multicomponent strain-gauge balance, wind tunnel
