The design method of the gap between the straight section of the end and the auxiliary spring of the oblique line type few-leaf main spring
A straight section, slanted line technology, which is applied to the gap between the straight section at the end and the auxiliary spring of the slanted few-leaf main spring, can solve the complex calculation of deformation, cannot provide analytical design formula, and cannot meet the requirements of small-leaf slanted springs. Design requirements for linear variable cross-section leaf springs, etc.
