This paper proposes a quasi-zero stiffness (QZS) isolator based on an inclined trapezoidal beam to explore its advantages in low-frequency passive vibration isolation. The nonlinear of the due buckling effect is investigated through finite element simulation, and linear positive spring connected parallel form QZS with high-static low-dynamic performance. natural frequency region simulated analy...
Fault diagnosis is an ongoing significant research field, due to the constant increasing need for maintainability, reliability and safety of industrial plants. The pneumatic actuators are installed mainly in harsh environment: high temperature, pressure, aggressive media, vibration, etc. This influenced on the Pneumatic actuator predicted lifetime. The failures in pneumatic actuator cause force...
Perceived comfort level and ride stability are the two most important factors in the evaluation of suspension system in a mobile vehicle. It is extremely difficult to simultaneously maintain a high standard of vehicle ride, handling and body control in the vehicle by using conventional passive suspension system. However, the use of active suspensions would result in better comforts than the pas...
Abstract To study the damage of shock vibration generated by ship hull to internal equipment under secondary explosion impact, a three-dimensional simulation model BE rubber isolator was established. The signal impact load loaded AUTODYN software. And relationship between primary and frequency, amplitude, attenuation loading found. It is revealed that law curve conforms rational function. Based...
Abstract Quasi-zero-stiffness (QZS) vibration isolators have been widely studied, because they show excellent high static and low dynamic stiffnesses can effectively solve low-frequency ultralow-frequency vibration. However, traditional QZS (T-QZS) usually adopt linear damping, owing to which achieving good isolation performance at both frequencies is difficult. T-QZS exhibit hardening stiffnes...
A mechatronic vibration isolation system has been developed on the basis of system theory. This equipment integrates mechanics, pneumatics and electronics in synergistic co-operation. The electronic control is responsible for the dynamic behaviour and the special computing transfer block for the real time interaction and compensation of floor vibration disturbances. INTRODUCTION The method for ...
