An online-adaptive hyperreduced reduced basis element method for parameterized component-based nonlinear systems using hierarchical error estimation
Mehran Ebrahimi, Masayuki Yano
We present an online-adaptive hyperreduced reduced basis element method for model order reduction of parameterized, component-based nonlinear systems. The method, in the offline ph…
Configuration Design of Mechanical Assemblies using an Estimation of Distribution Algorithm and Constraint Programming
Hyunmin Cheong, Mehran Ebrahimi, Adrian Butscher +1
A configuration design problem in mechanical engineering involves finding an optimal assembly of components and joints that realizes some desired performance criteria. Such a probl…
Optimal Design of Continuum Robots with Reachability Constraints
Hyunmin Cheong, Mehran Ebrahimi, Timothy Duggan
While multi-joint continuum robots are highly dexterous and flexible, designing an optimal robot can be challenging due to its kinematics involving curvatures. Hence, the current w…
A hyperreduced reduced basis element method for reduced-order modeling of component-based nonlinear systems
Mehran Ebrahimi, Masayuki Yano
We introduce a hyperreduced reduced basis element method for model reduction of parameterized, component-based systems in continuum mechanics governed by nonlinear partial differen…
Design optimization of dynamic flexible multibody systems using the discrete adjoint variable method
Mehran Ebrahimi, Adrian Butscher, Hyunmin Cheong +1
The design space of dynamic multibody systems (MBSs), particularly those with flexible components, is considerably large. Consequently, having a means to efficiently explore this s…
A low order, torsion deformable spatial beam element based on the absolute nodal coordinate formulation and Bishop frame
Mehran Ebrahimi, Adrian Butscher, Hyunmin Cheong
Heretofore, the Serret-Frenet frame has been the ubiquitous choice for analyzing the elastic deformations of beam elements. It is well known that this frame is undefined at the inf…
Optimal design of frame structures with mixed categorical and continuous design variables using the Gumbel-Softmax method
Mehran Ebrahimi, Hyunmin Cheong, Pradeep Kumar Jayaraman +1
In optimizing real-world structures, due to fabrication or budgetary restraints, the design variables may be restricted to a set of standard engineering choices. Such variables, co…
Optimal Design of Vehicle Dynamics Using Gradient-Based, Mixed-Fidelity Multidisciplinary Optimization
Hyunmin Cheong, Mehran Ebrahimi, Hesam Salehipour +2
In automotive engineering, designing for optimal vehicle dynamics is challenging due to the complexities involved in analysing the behaviour of a multibody system. Typically, a sim…
