Balance with double clamped parts

The invention belongs to the technical field of multi-component aerodynamic load measurement sensors, and discloses a balance with double clamped parts. The double-clamped-part balance is of a steel part combined structure, a left lug and a right lug are located at the left end and the right end of the steel part combined structure, and elements are located in the middle section; the element is composed of a left fixed end, a left measuring section, a left transition section, a free end, a right transition section, a right measuring section and a right fixed end which are sequentially connected from left to right. Aerodynamic force acting on the aircraft model is converted into voltage signals through the resistance strain gauges arranged on the two measuring sections, and the required aerodynamic force and torque are obtained after data processing is conducted on the voltage signals. According to the double-clamped-component balance, on the premise that the balance strength and rigidity and the sensitivity o
