An active suspension is a type of automotive suspension that uses an onboard control system to control the vertical movement of the vehicle's wheels and axles relative to the chassis or vehicle frame, rather than the conventional passive suspension that relies solely on large springs to maintain static support and dampen the vertical wheel movements caused by the road surface.
More recently, earlier this fall AAA cautioned that the safety systems can't completely protect vehicles from rear-end crashes, particularly those that happen at higher speeds in the 40-mph range ...
Early-1980s through early '90s, Lotus Engineering, the consultant branch of Lotus Cars, experimented with active suspension layouts, combining Electrohydraulic servo valve technology from aerospace, a variety of sensors and both analog and digital controllers. About 100 prototype cars and trucks (and several racing cars) were built for a wide ...
The shape of the subframe changed to an approximate triangle, bolted to the front of the differential and attached to the car at approximately the same points as the radius arms of the first generation IRS. The rear of the differential was further supported by a pair of link rods attaching it to the car's rear floor structure.
Each end of the bar is connected to an end link through a flexible joint. The link is connected in turn to a spot near a wheel or axle, transferring forces from the heavily loaded side of a suspension to the opposite. Forces are therefore transferred: from the heavily loaded side of the suspension; to the connected end link via a bushing
Using electronic stability control sensors to measure steering angle, vehicle yaw, and lateral acceleration and brake assist (BAS) sensors to detect emergency braking, the system can tighten the seat belts, adjust seat positions, including rear seats (if installed), raise folded rear headrests (if installed), and close the sunroof if it detects ...
Torsional vibration is a concern in the crankshafts of internal combustion engines because it could break the crankshaft itself; shear-off the flywheel; or cause driven belts, gears and attached components to fail, especially when the frequency of the vibration matches the torsional resonant frequency of the crankshaft. Causes of the torsional ...
Noise, vibration, and harshness (NVH), also known as noise and vibration (N&V), is the study and modification of the noise and vibration characteristics of vehicles, particularly cars and trucks. While noise and vibration can be readily measured, harshness is a subjective quality, and is measured either via jury evaluations, or with analytical ...
