 +==== Crawler vibration Measurement ==== 
 +Moreover, please check the  following factors. 
 + 
 +  
 + 
 +1.       relation between lug or (core bar) pitch of rubber crawler and arrangement of track rollers.  
 + 
 +2.       The dominant frequency of mechanical vibration of rubber crawler vehicle can estimate by driving speed / lug or (core bar) pitch of rubber crawler.  
 + 
 +In case lug or (core bar) pitch of rubber crawler is 0.084m and driving speed is 0.200m/s, dominant frequency of mechanical vibration of rubber crawler vehicle can estimate by 0.2/0.084=2.831Hz

 +Muneshi Mitsuoka fra Kyushu Universitet har skrevet PhD om vibrationer i baeltekoeretoejer. Han har ogsaa lavet noget software der kan simulere et design af baeltemodulerne. Jeg har uploadet praesentationen jeg har faaet af han [[http://www.google.com/url?q=https%3A%2F%2Fdocs.google.com%2Fopen%3Fid%3D0B1ilODNTH9nzanZBbk1RRmhXX0k|her]]. Jeg tror det er en god ide at tage med i overvejelsene af et nyt design. 
 +Her er link til deres artikler:  [[http://www.google.com/url?q=https%3A%2F%2Fdocs.google.com%2Fopen%3Fid%3D0B1ilODNTH9nzb3J2N1lwZW9yQms|artikel 1]] [[http://www.google.com/url?q=https%3A%2F%2Fdocs.google.com%2Fopen%3Fid%3D0B1ilODNTH9nzbUlNdHVuTVg1Tms|artikel 2]] 
 +=== Observations so far === 
 +  *Kraftoverfoersel fra drivhjul til baelte: Hvis drivhjulet placeres nede i bageste hjoerne af baeltet, vil drivhjulet traekke i baeltet der ligger paa jorden mens det  er belastet af hele robottens vaegt. Det burde goere baeltemodulet mere effektivt ved fremadkoersel., fordi der bliver trukket i stedet for skubbet. 
 +  *Baelte med stort drivhjul - Se ogsaa Armadillo 3 arbejdsdokument.\\ Det giver min 3 taender i baeltet hele tiden 
 +  *De 3 skiver/hjul i hvert modul der baere vaegten bevaeger sig op og ned hver gang de koerer hen over en af metal delene i baeltet og hullerne i mellem dem. Jo hurtigere man koere jo mindre er problemet, men ikke desto mindre er det med til at lave vibretioner i rammen. 
 +  *Vi har snakket med Prof. Meier fra TU Berlin. Han mete at vibrationerne kunne opstaa af flere grunde. 
 +    *Polygon effekt; jo stoerre drivhjulet er jo bedre. Det skal have et ulige antal taender, og det skal vaere 17 eller derover for at mindske effekten. 
 +    *Hvis huset er monteret paa daempere kan det skabe vibrationerne, pga. af den store masse der flytter sig frem og tilbage. 
 +    *Vibrationerne kan stamme fra alle tandhjul, og det kan vaere meget svaert at fidne ud af praecis hvor de opstaar henne. 
 +  *Observationer efter feltforsoeg: Hvis kaeden ikke er stram, bliver vibrationerne mindsket vaesentligt.
