4. Modeling a bent section
A cranked section is usually encountered when modeling a crankshaft, which is broken down into successive sections. These usually comprise a crankpin, the two connecting arms and the two journal halves (figure 16).
Two types of analysis are possible. The first uses the finite element method and requires volume meshing. This involves a considerable modeling effort. The second uses the British International Combustion Engine Research Association (BICERA) [1] method, which is applicable to all crankshaft shapes. This is the most accurate of the easy-to-implement methods, and takes full account of the actual...
