Frequency-based dynamic topology optimization methodology for improved door closing sound quality
(Sage, 2019-12-05)
Door closing sound quality of a vehicle has become one of the most important customer-related quality metrics in the recent years. There has been a vast amount of information on the design parameters contributing to this ...
Modeling and control of flywheel mechanical hybrid powertrain for real world conditions
(Canadian Acoustical Association, 2019)
This paper focuses on dynamical response characteristics of a flywheel mechanical hybrid powertrain (FMHP), comprising a continuously variable transmission (CVT) and a flywheel integrated into a conventional vehicle with ...
Topology optimization of an anti roll bar of a heavy commercial truck for vehicle dynamics and durability
(The American Society of Mechanical Engineers, 2019)
Meeting the stringent requirements on fuel economy and emissions is still a challenge for automotive original equipment manufacturers (OEMs). In this study, we consider the light weighting opportunities of a heavy commercial ...
Critical review of the factors dominating the fracture toughness of CNT reinforced polymer composites
(IOP Publishing, 2019-01)
In this study, the main factors, which have substantial influence on fracture toughness of carbon nanotubes (CNTs)-based composites both at nano and macro scales, are discussed in detail. Based on the findings from the ...
Topology optimization of constrained and unconstrained damping layers
(Canadian Acoustical Association, 2019)
Damping is an effective way of suppressing mechanical vibrations. Passive constrained and unconstrained layer damping patches are often used in the industry as damping solution for vibrations and acoustics problems. In ...
The effect of curvic coupling joints on the roto rdynamic characteristics of gas turbines with tie-shaft
(Canadian Acoustical Association, 2019)
The importance and use of curvic coupling joints are garnering interest in many aero-engine rotordynamics applications thanks to their benefits such as lower stress, higher service life, reliable positioning, precise ...
A new methodology to determine the design sensitivity of critical automotive body joints for basic design cycle
(Sage, 2019-09)
As a result of more stringent requirements for improved fuel economy and emissions, there has been an increasing research activity to make vehicles lighter weight under some predetermined structural performance targets ...
Review of the main factors controlling the fracture toughness and impact strength properties of natural composites
(IOP Publishing, 2019-02)
The main critical factors, which have direct influence on the fracture toughness and imapct strength properties of natural fibers composites, are reviewed in details in this paper. Considering the vast body of literature ...
Simplified transfer function approach for modeling frequency dependency of damping characteristics of rubber bushings
(Sage, 2019-09)
Physical systems that consist of parts and vibration isolators such as rubber bushings are usually modeled in multibody simulations, where parts are represented as rigid bodies with their mass and inertia properties and ...
Design and kinematics of 4- DoF multi-purpose wearable mechanical arm (MUWA) support for enhanced operation stability
(IEEE, 2019)
A low-cost motor-less simple wearable mechanical arm support unit is presented as a viable alternative to todays assistive exoskeleton support units. By limiting the functionality of the device to stabilization rather than ...
