I want to check the stiffness of the 914 chassis two ways: the flexural stiffness (as in measure the shock tower movement as you lift it from the middle), and the torsional stiffness ( measuring the shock tower movement as you lift three wheels).
Then I want to input a 914 chassis into a 3d structural software that I use. I will design a tube chassis and check the flexural and torsional stifness with different tubing and thickness layouts. Then construct the tube chassis and compare the real world results. I want input from others as to how they would go about doing this. Or maybe give me some pointers. Or maybe someone already knows the factory stiffness? What do you think? |
