Objective function and constraint conditions are both nonlinear functions, and the problem is summarized as a nonlinear programming problem with equality constraints and inequality constraints. According to the mathematical model established in the previous, the use nonlinear programming function ‘fmincon’ in the MATLAB optimization toolbox, programming the optimization procedure to run the optimization results.

3.4 Results and Analysis

Results after optimization as follow. The radius of the three section is R1 = 16.2883 mm, R2 = 11.4018 mm, R3 = 5 mm. The arc angles of the three sections arc are α1 = 0.3656 rad, α2 = 0.8018 rad, α3 = 0.5011 rad. The total length of the curve was L = 27.6506mm. According to the obtained results we can draw the return tube curve Figure 8. The impact force before and after optimization are shown in Figure 9 and Figure 10.
