【Abstract】 The applied the optimum design method for PC stand is designed. It set up mathematics model that regarded the least plus power’s sum of stand bounce value and frame weight as aim function, which included 7 design variables and 22 bind conditions and it used SUM method to calculate and got the best theme. If the theme compared to the old, the stand weight was reduced 23.566%, and stand bounce values were decreased 6.348%.更多还原
