Vibration Characteristic Prediction of a Heavy Machinery Suspension Seat Using Multi-Body Dynamic Analysis Method

This article proposes a novel simulation technique to predict the reasonable dynamic characteristics of a suspension seat for heavy machinery using a commercial multibody dynamic analysis code, ADAMS. The dynamic model is simulated with the specific condition such as sinusoidal and sweep input. The experiment test for actual suspension seat is conducted for reviewing the dynamic simulation model with same input condition. As the simulation results shows good agreements with experimental test results, the dynamic analysis model is reasonable and will be very helpful for predicting the dynamic characteristic for the suspension seat for heavy machinery and for designing the other type seats with the other suspension mechanism types.
