In this study, the vibration pad system used in the study of vibrations of the vehicle has been designed and built. The system uses the principle of the crankshaft-rods to create stimulating vibration function form of harmonic vibration frequency vertical can infinitely change (0-10Hz) thanks to changes the rotation speed of the electric motor and inverter machines use vibration amplitude can change (0-30 mm) by adjusting the length of the crankshaft to laboratory research with the mass suspension hanging small (< 300 KG) as suspension seats, the car cabin suspension. Test results showed that the system work stability, ease of use, the response is basically the parameters create vibration research of oscillation in the laboratory.file motion function

In this study, the system used in the study vibration pad oscillation of the car has been designed and manufactured. The system uses the principle of the crankshaft - connecting rod vibration excitation function to create functional form vertical harmonic vibration frequency can be changed stepless (0-10Hz) by changing the rotational speed of electric motors used inverters and amplitude can be changed (0-30mm) by adjusting the length of the crankshaft to research experiments suspension hanging small volume (<300 KG) as suspension seats, cabin suspension. Test results showed that the system worked stable, easy to use, meet the basic parameters for the research generated oscillating vibration of the car in the lab.

In the study, you use the system in the vibration of the vehicle vibration system has been designed and fabricated using the Qu Zhou principle of acoustic vibration stimulation, the transfer function and the vertical harmonic vibration frequency can be changed into the class (0 - 10Hz) required to change the rotation speed of the motor with inverter and Mechanical vibration amplitude can be changed (0 - 30mm) hanging through research and small quality of crankshaft system experiment to adjust the length (< 300 kg) such as seat suspension system, suspension system of vehicle cabin. Experimental results show that the system works stably and is easy to use, consistent with the basic parameters that produce oscillations in the vibration of the vehicle in the laboratory.Conditioned activation function
