The environmental factor influence model is also set up and the environmental influence model is calculated based on the environmental information. The model for the influence of microstructure deformation includes: ， in, For time The durability of the high-durability rubber bearing under stress is measured. It is the first adjustment factor for the stress index. For the number of chains, For time Time The length of the chain, Let be the initial length of the chain. It is the second adjustment factor for the stress index. For the first The chain rotates at an angle. It is the third adjustment factor for the stress index. For time The strain of the high-durability rubber bearing described above. This refers to the chain relaxation time. For time The strain of the high-durability rubber bearing includes: ， in, For the location of the high-durability rubber bearing Place Stress in the axial direction, For the location of the high-durability rubber bearing Temperature at the location The elastic modulus below, As the first adjustment factor for temperature, For the location of the high-durability rubber bearing Place Stress in the axial direction, The second adjustment factor for temperature. For the location of the high-durability rubber bearing Place Stress in the axial direction, It is the third adjustment factor for temperature. It is the fourth adjustment factor for temperature. For the location of the high-durability rubber bearing Temperature gradient at that location, It is the fifth adjustment factor for temperature. for Adjustment factor for axial stress. for Adjustment factor for axial stress. for Adjustment factor for axial stress; The environmental factor impact model includes: ， in, For time The durability of the high-durability rubber bearing under environmental influences. For initial durability, The primary adjustment factor for humidity. For the location of the high-durability rubber bearing Humidity at the location The second adjustment factor for humidity. It is the third humidity adjustment factor. It is the fourth humidity adjustment factor. For the location of the high-durability rubber bearing Humidity gradient at the location, It is the fifth adjustment factor for humidity. It is the sixth adjustment factor for humidity. It is the seventh adjustment factor for humidity; The analysis module is used to perform a weighted average of the durability affected by stress and the durability affected by the environment to obtain the final durability, thereby completing the durability analysis.
