Vehicle Performance Engineering

Vehicle performance is the study of the motion of a vehicle. The motion of any vehicle depends upon all the forces and moments that act upon it. These forces and moments, for the most part are caused by interaction of the vehicle with the surrounding medium(s) such as air or water (e.g. fluid static and dynamic forces), gravitational attraction (gravity forces), Earth’s surface (support, ground, or landing gear forces), and on-board energy consuming devices such as rocket, turbojet, piston engine and propellers (propulsion forces). Consequently, in order to fully understand the performance problem, it is necessary to study and, in some way, characterize these interacting forces.

How To Build An Electric Vehicle?

Disruption in the Automotive and Transportation industry is well under way. How we get from Point A to Point B is being reinvented due to increasing urbanization. This is driving the convergence of autonomous, electrification, connectivity and shared transportation systems rapidly. Auto OEMs and suppliers have to develop and execute new business models to prevent becoming obsolete as these mega trends unfold and technology innovation increases exponentially. The race is on for Auto OEM’s and suppliers to transform their business and provide multimodal mobility services for the future of mobility.

Simcenter Simulation: The Key to Make Safe Autonomous Vehicles

Simcenter Simulation: The Key to Make Safe Autonomous Vehicles

As vehicles become more automated with advanced driver assistance systems (ADAS), development and validation testing conditions need to be defined. Which scenarios should be considered for ADAS and future autonomous vehicles (AVs)? How can a large number of potential driving situations be considered and how can the most critical ones be identified? Can verification and validation (V&V) be managed in a realistic timeframe and at an acceptable cost? This blog post highlights a process applied during vehicle development, and discusses the support Siemens Digital Industries Software and ETS Solutions Asia engineering services team can provide.

What is Industry 4.0 in terms of Manufacturing, the innovations and trends

What is Industry 4.0 in terms of Manufacturing, the innovations and trends

By its nature, an Industry 4.0 implementation will be incremental, not big bang. Manufacturing will still need people and centralized information applications in addition to the new IIoT data for the next several decades. That’s where the systems that manage all that data, and the people, processes, products and machines that generate it – manufacturing operations management (MOM), or the next evolution of manufacturing execution systems (MES) – will play a critical role.

Noise and Vibration Monitoring Guidelines

Noise and Vibration Monitoring Guidelines

Noise and vibration are both dynamic processes and have a close physical relationship. Vibrating systems make noise, and noise makes structural systems vibrate. Both noise and vibration are adversely affecting people and if sufficiently intense, both noise and vibration can permanently hurt people. At the same time, also structural systems, if excited by excessive noise and vibration over sufficient periods of time, can fatigue and fail.
