     View Summary

    <p>For agricultural tractor, these two performances have been very important; high efficiency and maneuverability because the operator has increasingly required the fewer fuel consumption and easier and more precise control of the tractor. Generally speaking, hydro-mechanical transmission (HMT) is well known for the high efficiency level and the step-less variable speed. However, HMT is hydraulic powered system then hydraulic noise may more often occur than the pure mechanical transmission.</p><p>Therefore, this paper shows how to predict the sound pressure level with only using the design parameters of HMT and transmission assembly parts. 1-D hydraulic circuit simulation model and 3-D FEM model of HMT have been developed, and the simulated results of the sound pressure level has been calculated. Moreover, the calculated sound pressure level has been validated by the actual measured data and the cause of prediction error has been found. These all results suggest the possibility that the hydraulic noise can be reduced in an optimal way at the design process, without any prototype testing.</p>

  • Development of Variable Damping Force Damper using Pressure-resistant Thin-wall Metal Bellows Actuator

    SATO Yasukazu, SHIMBORI Takeyoshi

    The Proceedings of Mechanical Engineering Congress, Japan ( The Japan Society of Mechanical Engineers )  2018 ( 0 )   2018

    Joint Work

     View Summary

    <p>An active air suspension for posture control of a compact vehicle in motor-sports use has been developed. The active air suspension consists of a pressure-resistant thin-wall metal bellows air spring and a variable damping force damper. Both the stiffness of air spring and the damping force generated by the damper are controlled by the air pressure supplied to the suspension system. This paper presents the mechanism of damping force control, and the unique structure of the damper. Furthermore it shows the damper performance with 1-D simulation results and the damping force measurement.</p>
