Study on Vibration Characteristics and Human Riding Comfort of a Special Equipment Cab

Abstract EN

Special equipment drivers often suffered from vibration which threatened their physical and mental health.

In order to study the riding comfort of a special equipment cab, a hammering experiment has been carried out on it by acceleration sensors.

According to the test results, the natural frequency has been calculated which was compared with the result analysis by the finite element method.

Next, the equipment operating condition test on a flat road was done.

The vibration characteristics of the whole vehicle were obtained later.

The results show that the cab vibration and the finite element results agree well, but the natural frequency of the cab is close to the vibration frequency of the human body.

And this is not conducive to long-term operation of the drivers.

In order to improve the human operational comfort, it is necessary to reduce its natural frequency during the cab structure design process.

The research in this paper can provide help for the similar human-machine operation comfort study and product design.
