The Chebyshev's Lambda Mechanism〔http://demonstrations.wolfram.com/ChebyshevsLambdaMechanism/〕 is a four-bar mechanism that converts rotational motion to approximate straight-line motion with approximate constant velocity.〔 〕 The precise design trades off straightness, lack of acceleration, and what proportion of the driving rotation is spent in the linear portion of the full curve. The example to the right spends over half of the cycle in the near straight portion. The Chebyshev's Lambda Mechanism is a cognate linkage of the Chebyshev linkage. The linkage was first shown in Paris on the Exposition Universelle (1878) as "The Plantigrade Machine".〔http://mech.spbstu.ru/Dzenushko_Dainis:_Walking_mechanisms_survey#The_Chebyshev_Walking_Mechanism〕〔http://www.etudes.ru/en/etudes/stopohod/〕 The Chebyshev's Lambda Mechanism looks like the greek letter lambda, therefore the linkage is also known as Lambda Mechanism.〔http://www.etudes.ru/en/etudes/stopohod/〕 ==See also== *Straight line mechanism *Peaucellier–Lipkin linkage (an 8-bar linkage) *Chebyshev linkage *Four-bar linkage *Hoeckens linkage 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Chebyshev's Lambda Mechanism」の詳細全文を読む スポンサード リンク
