Structural optimization method for parallel load distribution type six-component force sensor

Abstract

The invention discloses a structural optimization method for a parallel load distribution type six-component force sensor. The parallel load distribution type six-component force sensor takes a central bearing beam as a load auxiliary support and the bearing capacity of the sensor can be greatly improved. Based on the condition that the parallel branched-chain force is fixed in the parallel six-component force sensor, the mutual influence rule of the range and structural parameters of the sensor is researched. According to the structural optimization method for the parallel load distribution type six-component force sensor provided by the invention, the maximum branched-chain bearing capacity of each branched chain in a safe working state is taken as a condition, the range of the six-component force sensor is used as a basic value at the moment, the central bearing beam and branched chain parameters are changed to obtain a new range of the sensor, and the structural parameters of the sensor are optimized by establishing a comprehensive incremental range model of the sensor. Compared with a traditional sensor structural optimization method, on the one hand, the parameter design of the central bearing beam is facilitated, so that the bearing requirement of the sensor is met; and on the other hand, the branched chain parameters of the sensor can be properly adjusted for optimization for the bearing requirement.

Description

technical field [0001] The invention relates to a structure optimization method of a parallel load-sharing type six-dimensional force sensor, which belongs to the technical field of measurement. Background technique [0002] Among the many sensors, the six-dimensional force sensor is particularly important because it can measure the force and moment in any three directions of the carrier, and has a broad application market in aerospace, industrial automobiles and other fields. With the continuous upgrading of the traditional manufacturing industry with smart factories as the core goal, in the application fields with limited measurement space and relatively large external loads, the structural geometry of the general six-dimensional force sensor needs to be continuously increased to meet the requirements for large external loads. Measurement needs. Therefore, the miniaturization requirements for large-scale six-dimensional force sensors are becoming increasingly stringent, a...
