Effect Of Input Angle, Dimenssion Ratio-Mechanism Link To The Output, Transmission Angle And Motion Characteristic
Abstract: In the previous
study, the design of a four bar linkage mechanism had been analyzed by using a
constant length dimension
of link. The
relationship between degree
inputs to degree output was generated by using
mathematic model of generator function. In this study, variation of length
dimension of link was investigated to find the characteristic the output motion
of four bar linkage mechanism. The input degree, ratio of link number 2 (R2),
ratio of link number 3 (R3) and ratio of link number 4 (R4) is chosen as
independent variable. It can be described by using output degree, transmission
degree, coupler degree and possibility of the motion path.
The result shows that the increasing rate of output degree number 4 on
the R2 variation is larger than increasing rate of output degree number 4 on
the variation of R3 and R4. Variation of R2 generated one working domain on the
input degree number 2 to output degree number 4. The coupler degree
on R2 variation produced
a larger domain
than it’s produced
by R3 and R4 variation. In addition, the transmission
degree for all control variables of R2, R3 and R4obtain apolynomial curve tends
to resemble as parabolic curve. For increasing of R3 and R4, the curve istransformed from
two domains into one
domain. Moreover, for
increasing of R2,
the curve is transformed in the opposite way.
