NAGARAJ GONI PRESENTATION ABOUT AUTO SUSPENTION.
The document discusses vehicle suspension components and geometry. It introduces common suspension types like solid axle, double wishbone, and MacPherson strut. It defines key suspension terminology like sprung mass, bump, roll, pitch, camber, and toe. It also compares advantages and disadvantages of different suspension designs and how their geometry can be tuned or adjusted.
Suspension system for any vehicle
The simulation of a vehicles suspension system represents an important part of how the driver experiences ride quality. Without a suspension system, a vehicle acts in a stiff and uncomfortable way. The characteristics of a vehicles performance are dependent on the properties of the suspension. A model of this system would enable a manufacturer to test how certain changes to the properties change the behavior of the vehicle. This way they are able to see how the stiffness of the spring and damper in the suspension system affects the ride experience before building an actual car. This can also reduce the cost of development. The most basic suspension system consists of a spring and shock absorber and also includes the stiffness of the tire being used. More complex suspension systems consist of sensors that take into account and compensate for traction control, engine torque, steering, and braking systems.

INDEPENDENT SUSPENSION SYSTEM
Independent suspension allows each wheel on the same axle to move vertically independently of the other. It is common for modern vehicles to have independent front suspension (IFS) and some to have independent rear suspension (IRS) as well. Independent suspension offers better ride quality and handling due to lower unsprung weight and each wheel's ability to react individually to the road. Some common independent suspension system types are MacPherson strut, double wishbone, and multi-link systems.
Foundation notes
Foundations transfer structural loads to the ground and include shallow foundations, such as spread footings, and deep foundations, such as piles. Piles are driven or drilled deep into the ground to gain bearing capacity from end-bearing or skin friction along their length. Pile driving involves using equipment like hammers, leads, and compressors to install piles, and dynamic testing helps evaluate pile capacity and optimize the driving system. Pile load tests provide a direct measurement of a pile's axial capacity. Proper installation and inspection techniques help ensure foundations perform as designed.

Single girder or double girder crane
A common misconception is that double girder
bridge cranes are more durable.
Based on the CMAA (Crane Manufacturers Association of America) specifications, both single and double girder cranes are equally rigid,strong, and durable. This is because single girder cranes use much stronger cross girders than double girder cranes, and single girder cranes have lateral bracing.
Electric chain or wire rope hoist
The technology for hoists is always improving. Chain hoists have become more durable, and new hoists are designed with lower headrooms. Currently, both electric chain and wire rope hoists are appropriate for typical factory applications in capacities to 7.5 tons.

Single girder or double girder crane
- 1. Single or Double Girder Crane A common misconception is that double girder bridge cranes are more durable. Based on the CMAA (Crane Manufacturers Association of America) specifications, both single and double girder cranes are equally rigid, strong, and durable. This is because single girder cranes use much stronger cross girders than double girder cranes, and single girder cranes have lateral bracing. The Difference is in the Hook Height The principle difference between single and double girder cranes is hook height (how far above the floor your hoist will lift). Double girder cranes provide better hook height.Double girders typically allow 18-36 inches higher lift. Double girder cranes can provide more lift, because the hoist is placed between the cross girders rather than under them. Therefore, the depth of the cross girder is gained in switching to double girders.
- 2. Cost Considerations Single girder cranes may cost less for several reasons: Only one cross girder is required The trolley is simpler Fright expenses are reduced Installation is faster Runway beams are lighter However, not all cranes should be designed with a single girder... ????? Single girder cranes have been built in spans over 100 feet and capacities of over 100 tons but typically cost effective engineering dictates that single girder cranes be considered as per the chart. Ultra Low Headroom (ULH) trolleys Double girder cranes typically have the hoist and trolley riding on top of the cross girders. As an option, we can provide a trolley that rides between the cross girders. This may be appropriate if: maximum hook height is required your cross girders, as well as your hoist, must be the maximum height above the floor you must minimize the distance above your runway beam you need the crane to be more compact
