General Lee: For such a TSP platform, indeed, is the test of the ability to integrate the same time, just She always has been mentioned in the business platform is a completely independent intellectual property platform and our platform is t In the shape of the design, the Core wing broke through the traditional appearance of the other models, the Core-wing sense of movement and high-level sense of the high degree of balance, which must be improved, both in the interior styling
Roll Centre and Centre of GravityTheres one final concept that ties theseideas together. A cars centre of gravity is another virtual point. If youimagine all the cars mass concentrated at one point, you have the idea of thecentre of gravity. In different cars the centre of gravity canbe at different heights above the ground (if the heavy objects in a car arelow, so will be the centre of gravity), and it can be closer to the front or tothe rear of the car. (For example, a rear engine car will have a centre ofgravity that is often rearwards.) In most cars, the centre of gravity isaligned on the central longitudinal axis of the car. So what has the centre of gravity got to dowith suspension? If the centre of gravity is higher than the roll centre, thecar will lean outwards when being cornered. In fact, the higher the centreof gravity is compared with the roll centre, the greater will be the lean for agiven cornering acceleration. Therefore, lowering the roll centreincreases body roll! If the roll centre is at the same height as the centre ofgravity, no roll will occur. If the roll centre is above the centre of gravity,the car will actually lean into the corner. Lets have a look at why these characteristicsoccur. We know that the cornering forces all get fed through the roll centre,and that the centre of gravity can be thought of as being the point where allthe cars weight is concentrated. If in this diagram theres a force pushingtowards the left at the roll centre, the car body will roll to the right.Thats because the vertical distance between the roll centre and the centre ofgravity creates a virtual lever arm (red). If the roll centre and the centre ofgravity are at the same point, no lever arm is developed and so no rolloccurs. Finally, if the centre of gravity is belowthe roll centre, a lever arm will develop that causes the car to lean theopposite way into the corner. Now of course this sounds very attractive, butit comes at the cost of having a high roll centre which in turn causes thejacking (and other) problems we referred to earlier. ConclusionIts very easy to get lost in suspensiondesign, especially when obscure terms are thrown about freely. However, bystarting with simple suspension systems, where the virtual ingredients canoften be actually seen, understanding what the ideas mean becomes a muchsimpler process.
