Multi-component test platform

The invention relates to the technical field of multi-dimensional force sensors, in particular to a multi-component test platform. A multi-component test platform comprises an upper platform and a lower platform, the upper platform is used for placing and fixing a tested body, the lower platform is provided with a plurality of groups of test pieces, and the plurality of groups of test pieces are respectively used for measuring forces in a plurality of directions. The lower platform is provided with decoupling pieces used for measuring non-axial force applied to the test pieces by a tested body in real time, and the decoupling pieces and the test pieces are in one-to-one correspondence. The multi-component test platform has the following effects that when the tested body applies forces in multiple directions to the multi-component test platform at the same time, the forces in the multiple directions influence each other to generate a coupling error, the decoupling member measures the non-axial force applied to
