The stressdistributionsof the original (Figure23a)andoptimizedconnectingplates (Figure23c)werecompared. Themaximum stressof thesolidconnectingplate is23.464MPainFigure23a. Themaximumstressof theredesigned one is34.66MPa,asseen inFigure23c.At thesametime, themaximumdeformationof theoriginal connecting plate appeared to be 0.0087mm in Figure 23b comparedwith the redesigned one of 0.0064mm,showninFigure23d. Themassof theoriginal connectingplate is3733.6g. Theweight decreasedto2150.9gwithaweight reductionofabout42.4%.Thestrengthcanmeet therequirements andthedistributionofstressbecamemoreuniform.
