Acceleration analysis procedure by relative acceleration method

ACCELERATION ANALYSIS PROCEDURE BY RELATIVE ACCELERATION METHOD

In this method, the acceleration of links in a mechanism are determined using the following steps.

Step 1: Construction of configuration diagram

Step 2: Calculation of velocity of input link

Step 3: Construction of velocity diagram

Step 4: Determination of velocity of various links

Step 5: Construction of acceleration diagram

Using the velocity of various links that are obtained with the help of velocity diagram, the values of radial and tangential components of acceleration of various links can be calculated as shown in Table 2.1 below.

Table 2.1. Radial and tangential components of acceleration of various links

By using the known values of magnitude and direction of acceleration components, the acceleration diagram can be constructed.

Step 6: Determination of acceleration of various links

By measurement from the acceleration diagram, one can determine the acceleration of various links of the given mechanism.
