Overview PREFACE Leaf springs are crucial to automotive suspension systems for their ability to distribute weight and absorb road shocks. Found commonly in trucks and heavy-duty vehicles, leaf springs consist of multiple layers of tempered steel connected at their ends by clips or bolts, forming an arch. Despite…
Overview PREFACE Physical vehicle testing is expensive and resource intensive. Vehicle modeling and simulation provide an efficient addition to the design process which can be implemented prior to physical testing to understand a vehicle’s dynamics. Multibody dynamics software, like Altair MotionSolve, allows users to set…
Overview PREFACE Driving a vehicle while hauling a trailer can be challenging, more so if the trailer is susceptible to instability. In the design and loading of a trailer it is crucial to be aware of the trailer’s center of gravity. A center of gravity behind the trailer’s axle can cause small disturbances to lead to…
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…
