[0033] The static test assembly includes a right support base 10 , a loading handle 11 , a lock 12 , a force sensor 13 , a D-shaped adjustment buckle 14 , a support base 15 and a support

[0051] This embodiment provides a thermal-mechanical coupling strain measurement method for an aluminum housing bearing seat, which uses the thermal-mechanical coupling strain measurement system for an aluminum housing bearing seat described in Embodiment 1, and the method includes:

[0052] S10, pasting the strain gauge and the temperature compensation sheet.

[0053] In this embodiment, the transmission assembly to be measured is disassembled, and the aluminum housing of the transmission assembly is simulated and calculated, and strain gauges are pasted on the maximum stress position of the bearing seat of the transmission assembly or the concerned part.

[0054] Among them, in the high-temperature thermal-mechanical coupling strain test, the resistance strain gauge is pasted at the end face of the bearing seat close to the bearing hole side, and a set of strain gauges is pasted on the theoretically loaded maximum stress of the front bearing seat and rear bearing seat of the tra
