Abstract: To solve the problem of large error in traditional testing methods for automotive aluminium alloy materials, a testing method for mechanical properties of automotive aluminium alloy materials based on elastohydrodynamic model was proposed. Firstly, the elastohydrodynamic model of automobile aluminium alloy material is constructed to obtain the bearing capacity and strength of automobile aluminium alloy material. Secondly, based on the elastohydrodynamic model of automobile aluminium alloy material, the load and yield strength of automobile aluminium alloy material mechanical components are analysed, and the vehicle use is estimated. Parameters of mechanical components of aluminium alloy materials. Finally, the mechanical properties of automotive aluminium alloys were further optimised by the evaluation method of under-actuated two-degree-of-freedom mechanism and the calculation of the coupling eigenfunction of mechanical properties of aluminium alloys and the energy equation of the relationship between friction force and friction coefficient.

Keywords: elastohydrodynamic model; aluminium alloy materials; mechanical properties; thermoelasticity; testing method; mechanical components.
