Analysis of Dynamic Characteristics

Analysis of Strength Characteristics

The force exerted on the left and right brackets is 8 times the suspension preload, and the maximum stresses of the left and right brackets are 104.9MPa and 215.3MPa<280MPa respectively, meeting the strength requirements of the brackets.

Note: The maximum stress of the bracket under 8 times the suspension load shall not exceed the yield strength of ZL201, 280MPa.
