Technical Field

the invention relates to the technical field of angular accelerometers, in particular to a sintering device and a sintering method for an electrokinetic converter of a molecular electronic angular accelerometer.

Background

The molecular electronic type angular accelerometer is used for measuring angular acceleration signals of a carrier relative to a corresponding axis, the working principle of the molecular electronic type angular accelerometer is that charges at an interface between an electrokinetic transducer and liquid are transferred to form potential difference by utilizing the flowing of working liquid in a sensitive assembly of the molecular electronic type angular accelerometer, and the potential difference at two ends of the electrokinetic transducer is measured through electrodes, so that electric signals corresponding to external angular acceleration signals are directly obtained.

The electrokinetic transducer of a molecular electronic type angular accelerometer is one of the key parts of a molecular electronic type angular accelerometer. A plurality of minute pores are distributed in the electrokinetic conversion device, and as the liquid flows through the pores, the walls of the pores have an affinity for certain cations, which are adsorbed within the pore wall structure. Therefore, the surfaces of the pores are charged due to the adsorption of ions, ions with the electric property opposite to that of the surfaces of the pores and the same electric charge are distributed in the working liquid around the pores, so that the working liquid is charged, and when the charged working liquid flows due to the angular acceleration information outside, an electric signal is formed. Therefore, the stability of the structural state of the electrokinetic transducer is one of the key factors for the normal operation of the molecular electronic type angular accelerometer. However, the angular accelerometer electrokinetic transducer manufactured by the existing process method has poor strength due to nonuniform sintering, and micro-bead particles fall off on the surface during use, so that the working precision of the accelerometer is affected.
