UK-based Ogle Models & Prototypes has purchased a second RPS Neo 800 machine to help improve turnaround times for larger models and prototypes within tighter timescales.

This 3D printer will allow Ogle’s specialist team to introduce a second clear material to the varied and high-end list of materials they already use for their Stereolithography (SLA) work.

The Neo 800 has a bed size of 800 x 800 x 600mm, which means larger parts can be made while retaining accuracy.

Topology optimisation with fatigue analysis cuts sports bike weight by over 80kg

Topology optimisation has been credited with helping reduce the Vins Motors Duecinquanta motorbike’s weight to 95kg, and a mere 85kg for its track sibling.

Vins’ Duecinquanta was designed with the help of fellow Italians Asotech and Ansys’ Mechanical software package, using simulation to iterate the motorcycle’s design, with Ansys Mechanical topology optimisation and fatigue analysis tools key to the project.

Asotech and Vins started with the Duecinquanta’s frontal node, loading the geometry of the part into Mechanical and assigned it a series of loads before defining areas of the part that needed to remain constant — like connections to other parts.

With the latest AMD Radeon Pro Enterprise driver (19.Q3) designers and engineers can experience wireless VR for select professional applications using Radeon ReLive for VR.

To deliver the untethered VR experience, the rendering is done on any ‘VR Ready’ AMD Radeon Pro WX series GPU (WX 7100, WX 8200 and WX 9100) and then streamed over WiFi to the VR headset. AMD supports the HTC Vive Focus Plus and Google Daydream.

Simcenter Madymo improves Active Human model for enhanced safety simulation

Published 16 August 2019

Posted by Stephen Holmes

Article tagged with: simulation, siemens, simcenter

Simcenter Madymo can simulate the impact of a car crash on the human body using Simcenter Active Human software, with the latest version now with solver run times reduced by 28 per cent over previous releases.

A Simcenter Active Human is a digital twin of an average adult male, with the model able to simulate a human body reacting to movements whilst maintaining posture with the use of a unique musculo-skeletal form guided by a control system of sensors and actuators - perfect for crash simulations.

The latest version of model has been extended with new features, including an active shoulder control, strength scaling, and drowsiness, sleep and unconsciousness modelling, helping users to accurately model human-like reactions needed for safer autonomous vehicle design.
