According C reciprocating solidwoodpanel saw ovenall layout,design theoverallprogram ofthemachine;briefly describe ponents program,and initially settheoverallprogramparameters;narough theanalysis ofthe C panel binedⅥ疽t11 theprocessing characteristics,determine theoverall structure ofthisdesign,and analysis themovement constituteprogram C reciprocating solid wood panel carry out adetailedanalysis and calculation ofmain motion system and feedsystem C reciprocating solidwood panel saw,including theselectionofthegear rack,the selectionofthe servomotor,toensure reliableoperation ofthemachine. Forthestudy ofstaticanddynamic performance ofthemachine,Perform staticanddynamic analysis ponents ofthemachine with ANSYS finiteelement analysis software. Through thestaticstudy found ponents ofthe stressand straincloud cloud safetyfactor toexamine thestrengthand stiffnessof studymainly ismodal analysis,and modal analysis ponents toget theformer naturalfrequencies andmodeshapes,then calculate thecriticalspeed shafting,in order tostudy Machine vibration stabilityanddynamic response thenanalysis thespindle structuralweaknesses. Using Solidworks software C reciprocating saWS wood panels solidmodeling,assembly andmotion motionsimulation analysis found ings existing inthe design,improvement andperfection inadvance to get
