Costin and Phipps Appendix I question
Costin and Phipps Appendix I question
(OP)
I have a question regarding the methods used to analyse a frame in the appendix. You are suppose to take a safety factor of 1.5 and then multiply it by 3 to simulate a 3g bump at the wheel. I thought 3g's was very low for the given example of hitting a curb. No damper or spring rates were given to make sense of the effects of the forces at the wheel on the frame. I must be understanding this incorrectly because this is just not right. I was hoping someone had a copy of this classic and could provide some guidance.

In your thinking you need to separate out the instantaneous shock acceleration on the spindle, from that distributed into the body. The latter is a lot smaller than the former.

Do you know how the 3-2-1 method compares to modern or even 80's/90's methods? What about road cars?
