Overview INTRODUCTION As drones become increasingly prevalent, collision avoidance is emerging as a critical feature of drone technology. Drones are used for many purposes, ranging from surveillance to delivery, increasing the risk of mid-air collisions. To mitigate this risk, simulation tools like Altair’s MotionSolve and…
Overview INTRODUCTION The landing gear on any aircraft is a critical feature paramount to passenger safety which requires careful and comprehensive design and analysis. The landing gear must survive takeoffs, taxiing, and most importantly landings, with a large margin for safety. It should fold into the aircraft to occupy…
Overview INTRODUCTION Multibody dynamics (MBD) simulation is the study of the dynamics of interconnected rigid or flexible bodies. Using MBD simulation, designers and engineers can analyze the motion, forces, and stresses in a wide range of mechanisms. By implementing simulation early in the design phase, engineers can…
Overview INTRODUCTION This study presents a CAE multibody dynamics simulation of a car door slam event, focusing on detailed kinematic models of hinges, latches, and sliders. The simulation evaluates dynamic constraints, structural integrity under impact, and stress distribution considering material properties. This…
Overview This extension adds a new "Flightstream Tools" ribbon. It provides an easy way to export a meshed model to Altair Flightstream in the OBJ format. The export tool allows the user to select the components to export and select the file to export to. The organisation of the mesh will be respected in the OBJ file…
Overview A simple tcl HyperMesh script to segregate surfaces in a single component to multiple components based on attached surfaces. Usage/Installation Instructions 1) Run the tcl script in the HyperMesh session. 2) Select components with multiple surfaces in a single component. The script will find surfaces attached…
Overview The presentation focuses on a ballistic impact quarter model. The bullet considered is a 5.56 x 45 SS109. The target is a 6.5mm 500T Armox steel plate. This article includes: * A ready to use Altair Radioss model of the bullet impacting the steel plate * Altair Radioss version is 2023.0.1 and later * The unit…
Overview Brake in Turn Maneuver Red – Passive System | Blue – Active Rear Wheel Steer PREFACE Physical vehicle testing, especially involving automated driver assist systems (ADAS), is expensive and resource intensive. Vehicle modeling and simulation provide an efficient augmentation which can be implemented earlier in the…
Overview EDEMpy is a Python library for post-processing and analysis of EDEM simulation data and takes advantage of EDEM's hdf5 file structure. Using the library, it is easy to extract specific data from a simulation deck and process that data in a customizable and reusable way. In this example a custom property has been…
Overview Enhancement to existing script ID 709. Utility to create MPCs for modelling cyclic symmetry on a solid mesh wedge model. Usage/Installation Instructions 1. Create faces on the solid elements and a cylindrical coordinate system at the centre with the z axis in the models axial direction 2. Run the utility…
