With the rapid iteration of sensor technology, higher requirements are put forward for the structural design of multi-component force sensors, and the spokes, as an important part of multi-component force sensors, directly affect the stress of multi-component force sensors. In order to solve the problem of excessive stress concentration in the non-strain zone and improve the overall force situation, the structure optimization and comparative analysis of the spokes in the spoke multi-component sensor are carried out. Aiming at the theoretical analysis of hub-and-spoke elastic elements, the implementation of the spoke structure of different spoke sensors is proposed, and the stress condition is simulated by the finite element method. In the experiment, the indication error in the static characteristics is selected, and the test results meet the design requirements, and the embodiment of the differences of different forms of hub-and-spoke sensors is further analyzed, reflecting the improvement of the stress status of multi-component sensors by the optimization of the spoke structure, which verifies the correctness of this study. This research result can provide some reference for the design and selection of hub-and-spoke multi-component sensors.
