It is effective to analyze the camshaft strength through FEA
method during the design phase. The dynamic loads on camshaft
could be got by using one-dimensional dynamic simulation on valve
train. Then the three-dimensional transient dynamic FEA could be
carried out, when the one-dimensional simulation result was as input
loads. The strength evaluation of camshaft could be crarried out after
the stress course was calculated. With practical experiments, this
method is proved effective to check design scheme and provide
reference for choosing camshaft material.
