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…
