Abstract

The invention relates to a six-dimensional acceleration transducer, comprising an inertial mass ball platform, a lower platform, a paster and six branched chains which are divided into three groups. The connecting points of the three groups of branched chains and the inertial mass ball platform are all located on the horizontal circumference with the largest diameter of the inertial mass ball platform and are distributed evenly; the connecting points of the three groups of branched chains and the lower platform are located on the same circumference and are distributed evenly; each branched chain consists of an elastic connecting rod and cylindric hinges arranged at the two ends of the elastic connecting rod; the cylindric hinges and the elastic connecting rod are at the same axial lead; and the inertial mass ball platform, the lower platform, the six branched chains and a boss are processed in an integral manner, which is characterized in that a through hole is arranged at each elastic connecting rod, the axial lead of the hole is vertical to the lateral surface of a circular truncated cone on which the six elastic connecting rods are located, two symmetric pasters are arranged corresponding to each hole, and each paster is adhered on the inner wall of the hole along the axial lead direction of the elastic connecting rod. The invention has the advantages of small design error, good dynamic properties, rapid response and high precision.

Description

technical field

[0001] The invention relates to a six-dimensional acceleration sensor, specifically a six-dimensional acceleration sensor based on a novel parallel structure and introducing a stress concentration factor method, which belongs to the field of testing technology and control. Background technique

[0002] The six-dimensional acceleration sensor is a difficult point in the field of sensor research. There are few domestic and foreign literature reports and patent applications because it is difficult to construct an elastic element that can simultaneously measure three-dimensional linear acceleration and three-dimensional angular acceleration. At present, it mainly focuses on the development of acceleration sensors below three-dimensional , and the technology is mature and has been commercialized.

[0003] The research on the six-dimensional acceleration sensor is still in the exploratory research stage at home and abroad. The typical elastic element structure is t...
