Parameter influence law analysis and optimal design of a dual mass flywheel

International Journal of Mechanical System Dynamics, Volume 2, Issue 2, Page 165-177, June 2022., 2022
Abstract The influence of the dynamic parameters of a dual mass flywheel (DMF) on its vibration reduction performance is analyzed, and several optimization algorithms are used to carry out multiobjective DMF optimization design. First, the vehicle powertrain system is modeled according to the parameter configuration of the test vehicle. The accuracy of

Robot joint friction compensation learning enhanced by 6D virtual sensor

International Journal of Robust and Nonlinear Control, Volume 32, Issue 9, Page 5741-5763, June 2022., 2022
Abstract High‐performance robot control is one of the most investigated topics in both research and industry. Being able to compensate for robot dynamics is indeed one major challenge. Joint friction is commonly the main issue, especially in sensorless (i.e., no availability of torque/force sensors) compliance‐controlled robots for interaction ...

Dynamic friction modelling without drift and its application in the simulation of a valve controlled hydraulic cylinder system

Journal of Advanced Mechanical Design, Systems, and Manufacturing, 2014
The frictional modelling literature is reviewed, and it is demonstrated that unrealistic drift results when the shape coefficient is 1.0 for the LuGre and the integral friction models.

Modelling and Identification of the Hysteretic Dynamics of Inerters

Designs, 2020
This paper deals with an experimental study on the modeling and identification of the hysterical behavior of inerters. Unlike existing methods that can only consider a constant inertance to capture a static model of the device, we develop three different
