Abstract
Stabilizer bar suspension system of a vehicle chassis in one of the important parts, you can ensure vehicle ride comfort under the premise of the roll angle increased suspension stiffness, making the car turn in the road uneven, or when the body can reduce the angle, smooth ride that both the car handling and stability. Currently on the market regardless of cars, sport utility vehicles are equipped with the basic installation of the horizontal stabilizer bars, buses, trucks, more and more of the assembly of the horizontal stabilizer bar. Vehicles equipped with a stabilizer bar in the stable, comfortable, greatly reduce the chance of rollover. According to statistics, poor road conditions, a sharp turn when the vehicle overturned with stabilizer bar reduces the probability of 60% to 80%. Therefore, the design process of vehicle suspension, stabilizer bar design and calculation is very important. Traditional mechanical methods can only approximate the response to the loading force and deformation, can not meet the need for further analysis, and ANSYS software is the solution to this kind of problem for the design. It is the most advanced analytical methods, the use of finite element based on theoretical platform technical analysis, prediction, and eva luation of these key components of the strength of stiffness.
ANSYS software described in this article is to use three-dimensional modeling of the horizontal stabilizer bar, the definition of cell types and material properties, meshing, and then put the corresponding node on the specific constraints, and then a section of the surface of the roll bar to exert power, and finally ANSYS software processors operating on the above calculated results. From the results obtained after the force displacement data, through the angular stiffness formula of calculation of angular stiffness, then the results will be compared with the traditional calculation method.
