What is a jacking force in suspension?
Jacking forces are the sum of the vertical force components experienced by the suspension links. The resultant force acts to lift the sprung mass if the roll center is above ground, or compress it if underground. Generally, the higher the roll center, the more jacking force is experienced.
How do you find the jacking force?
Friction force usually constitutes the main component of jacking force. It can be calculated by multiplying an effective friction coefficient and the normal force acting on the external surface of the pipe.
What is jacking technique?
Jacking is a term used to describe the application of a force with the aim of pushing or lifting an object. This act is typically done by mechanical means using several different devices.
What is jacking effect in cars?
Jacking forces are the sum of the vertical force components experienced by suspension links. The resultant force acts to lift the sprung mass, if the roll center is above ground, or compress it, if underground. Generally, the higher the roll center, the more jacking force is experienced.
What is scrub radius in automobile?
The scrub radius is the distance at the road surface between the tire center line and the SAI line extended downward through the steering axis. The line through the steering axis creates a pivot point around which the tire turns. If these lines intersect at the road surface, a zero scrub radius would be present.
What is post tensioning work?
Post-tensioning is a method of prestressing in which the tendons are tensioned after the concrete has hardened and the prestressing force is primarily transferred to the concrete through the end anchorages.
What is pipe tunneling?
Direct pipe tunneling is a trenchless technology combining the strengths of Horizontal Directional Drilling (HDD) and microtunneling. Pipe is laid in a single operation with steerable equipment thus saving time and money.
What is Jack piping?
A jacking pipe is a high compressive strength pipe that is jacked into the earth using the pipe jacking technique. The pipes are jacked through the soil by using hydraulic jacks that drive the shield at the front of the pipe string.
What is camber gain?
Camber Gain is the difference of the camber angle after a certain amount of suspension travel, typically 1″ of suspension dive (compression). Such as the camber is -3 degrees and goes to -4.5 degrees at 1″ dive, it has -1.5 degree Camber Gain.
What is castor adjustment?
Caster is an alignment adjustment that occurs on the turning wheels only, i.e., the front wheels of a vehicle.
