Overview INTRODUCTION Planetary gearboxes are useful for their compact design, high torque density, and efficiency. They distribute load across multiple gears, enhancing reliability and durability while reducing maintenance. Modular construction allows flexibility in gear ratios, accommodating specific operational needs.…
Overview INTRODUCTION The excavator is a staple of construction equipment seen on construction sites around the world. The simulation of heavy machinery, like the excavator, is crucial for optimizing design and improving performance. Utilizing multibody dynamics (MBD) software, engineers can analyze the mechanical systems…
Overview INTRODUCTION Designing an airplane for safe, controlled landings is one of the most challenging tasks aerospace engineers face. The landing gear must absorb the impact of landing and limit shock to the airframe. The airplane must remain stable and in pilot control during a landing under various weather conditions.…
Overview INTRODUCTION Landing gear are employed on most aircraft for ground operations and landings. Engineers must design landing gears to handle the impact loads during aircraft touchdown and absorb the shock of the landing to prevent damage to the aircraft. There are three main types of struts used in the aircraft…
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 earlier in the design cycle to understand a vehicle’s dynamics. Multibody dynamics software such as Altair MotionSolve allows users to…
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…
