Abstract
The choice of cam profile is a matter of primary significance in the procedure of valve gear design. It is long since dynamic design methods were first proposed and used, but even so, shortcomings still exist. One is that the conventional method does not take into account the non-linearity and hysteresis characteristics of valve train stiffness.
This paper describes a new dynamic design method of determining cam profile, including the ramp period, in which the above hysteresis characteristics as well as other factors are reasonably taken into consideration.
Experimental investigations have shown that the new method is effective over a wide range of operating conditions.
