Hey, I've spent ages trying to solve what seems to be a pretty simple geometrical problem and I was wondering if anyone could help me solve it/give me some tips. I am trying to model how the suspension of a car behaves as a result of a displacement of the wheels. What the attachment shows is a double wishbone suspension connected to a fixed chassis - similar to these sorts of mechanics: http://rezachu.blog.com/files/2012/12/KugelPushrod.jpghttp://rezachu.blog.com/files/2012/12/KugelPushrod.jpghttp://poisson.me.dal.ca/~dp_10_14/oldarchitecture/images/bc.bmp The suspension arms rotate about the fixed pivots on the chassis (at points A and E) and the push rod goes on the compress a spring/damper. So my question is: for an anti clockwise change in angle (delta) in the horizontal member, AC, how will this deflection affect the position of D, G and H - all in terms of the given geometry and angle, delta. Apologies if I have not phrased my question clearly. Any advice would be appreciated.
