Machines used in construction environments typically include an operator seat mounted in an operator cabin of the machine. Such machines are subjected to high amount of vibrations in the dynamic construction environments. Thus, it is important to test the operator seats to validate an ability of a suspension system of the operator seat to survive in such construction environments. Accurate validation of a performance of the suspension system allows protection of the operator seat from failures white also eliminating need of an expensive system of testing such operator seals. Typically, Multi-Axis Shake Table (MAST) test is used to validate the ability of the suspension system of the operator seal. For ihc MAST test, an operator is replaced with a ballast. A lorso mass of the operator is simulated by the ballast but the operator's input reacting to seal movements is not replicated by the ballast. Further, arms and legs of (he operator are also not simulated and thus the ballast can Hop unnaturally. More particularly, arms and legs of the operator are complicated to simulate as they are active and are often in different posilions such as sleering wheel or other control devices.
