Optimization of Process Parameters for Stretch Blow Molding of Beverage Bottles Based on Compressive Strength
The joint simulation method of bottle molding and compressive performance analysis in ANSYS is studied to improve the development speed of beverage bottles.The orthogonal experiment and the multi cycle experiment are carried out.and the parameter fitting with key process parameters as variables and compressive strength as dependent variables is carried out.The fitting parameters are as follows:a is 925.136,b1 is-3300.279,b2 is-7.717,c1 is 5738.422,and c2 is-1.437.The single objective optimization calculation with the maximum compressive strength as the objective is carried out.The results of single objective optimization are as follows:when the inflation delay time is 0.5s and the high inflation pressure is 3.2MPa.The experimental results show that under the conditions of the process parameters,the obtained results are very close to the optimization results.
