Direct-drive Wheel
A direct-drive simulator steering wheel (sometimes abbreviated "DD") is a Racing wheel, simulator steering wheel with a direct-drive mechanism between the drive and output, i.e. without gear ratio, gearing (as opposed to simulator steering wheels with reduction gearing via gears or belt drive, beltsAsada, H., & Kanade, T.

Racing Wheel
A simulator racing steering wheel is a control device for use in racing video games, racing simulators, and driving simulators. They are usually packaged with a large paddle styled as a steering wheel, along with a set of pedals for accelerator, brake, and clutch, as well as transmission controls. An analog wheel and pedal set such as this allows the user to accurately manipulate steering angle and pedal control that is required to properly manage a simulated car, as opposed to digital control such as a keyboard. The relatively large range of motion further allows the user to more accurately apply the controls. Racing wheels have been developed for use with arcade games, game consoles, personal computers, and also for professional driving simulators for race drivers. One of the earliest racing wheels for the PC mass market was the Thrustmaster Formula T1, released in 1994. It had no force feedback, only some form of spring-based centering resistance proportional to the steering ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Direct-drive Mechanism
A direct-drive mechanism is a mechanism design where the force or torque from a prime mover is transmitted directly to the effector device (such as the drive wheels of a vehicle) without involving any intermediate couplings such as a gear train or a belt.Asada, H., & Kanade, T. (1983) Design of direct-drive mechanical arms' in ''Journal of Vibration, Acoustics, Stress, and Reliability in Design'', Volume 105, Issue 3, pp.312-316 History In the late 19th century and early 20th century, some of the earliest locomotives and cars used direct drive transmissions at higher speeds. Direct-drive mechanisms for industrial arms began to be possible in the 1980s, with the use of rare-earth magnetic materials. The first direct-drive arm was built in 1981 at Carnegie Mellon University. Today the most commonly used magnets are neodymium magnets. Design Direct-drive systems are characterized by smooth torque transmission, and nearly-zero backlash.Bruno Siciliano, Oussama Khatib (Eds., 2008) ...

Performance Indicator
A performance indicator or key performance indicator (KPI) is a type of performance measurement. KPIs evaluate the success of an organization or of a particular activity (such as projects, programs, products and other initiatives) in which it engages. KPIs provide a focus for strategic and operational improvement, create an analytical basis for decision making and help focus attention on what matters most. Often success is simply the repeated, periodic achievement of some levels of operational goal (e.g. zero defects, 10/10 customer satisfaction), and sometimes success is defined in terms of making progress toward strategic goals. Accordingly, choosing the right KPIs relies upon a good understanding of what is important to the organization. What is deemed important often depends on the department measuring the performance – e.g. the KPIs useful to finance will differ from the KPIs assigned to sales. Since there is a need to understand well what is important, various techniques ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Multibody Simulation
Multibody simulation (MBS) is a method of computer simulation, numerical simulation in which multibody systems are composed of various rigid body, rigid or elasticity (physics), elastic bodies. Connections between the bodies can be modeled with kinematics, kinematic constraints (such as joints) or force elements (such as spring dampers). Unilateral constraints and friction, Coulomb-friction can also be used to model frictional contacts between bodies. Multibody simulation is a useful tool for conducting motion analysis. It is often used during new product development, product development to evaluate characteristics of comfort, safety, and performance. For example, multibody simulation has been widely used since the 1990s as a component of automotive suspension design. It can also be used to study issues of biomechanics, with applications including sports medicine, osteopathy, and human-machine interaction. The heart of any multibody simulation software program is the solver. The so ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
