Shi, L., Yi, P., and Zhang, Z., "A Method for Body Joint Stiffness Evaluation and Target Setting," SAE Technical Paper 2016-01-1330, 2016, doi:10.4271/2016-01-1330.
The body joint stiffness plays an important role in achieving vehicle attribute targets. One of the major drawbacks of joint stiffness evaluation is the lack of a rigorous criterion to assess whether the stiffness is proper for a body structure. This paper presents a general joint stiffness metric based on Hooke's law to better evaluate the stiffness of a body joint. A strategy for target setting of body joint stiffness was developed for vehicle body design. Finally, a vehicle body example was presented to demonstrate the proposed methodology.
