This paper describes an experimental program of tire research used to quantify the concept of the “relaxation length” of the fully rolling, steered tire. STEP 3: Integrate the moment equation once to get slopeRecall that the deflection of a beam is defined by the following differential equation: Substituting the derived moment equation and integrating the equation once gives the following expressions: At the fixed end of the beam, the slope is zero. Figure 9(a) and (b) shows that the cable displacement obviously decreased and its stiffness significantly increased with two deflection suppression systems installed. w2(x) and k2(x) are curves with cable and deflection system arranged as shown in Figure 3(a), where w2(x) and k2(x) are deflection and stiffness curves, respectively. When the boundary number is more than 4, the increased boundary constraints have small effects on the positions of minimum stiffness. When cable is constrained only by two boundaries, the minimum stiffness with the top tension varying curve is denoted by Kmin and the position of minimum stiffness with the top tension varying curve is denoted by εm.

In the case of a cantilever beam, the max deflection occurs at the end of the beam. This equation represents the lateral stiffness of the structure and its formation requires the calculation of an inverse matrix A 11 −1. Because of the large bending stiffness suit for 1500-m-length cables, the deflection deviation ratio is 11.06% at the position of 100 m. When the position range is 200–500 m, the deflection deviation ratio is less than 5%. A total of 24 static tests of drive-in rack systems have been conducted under single-point horizontal force. We will use a cantilever beam as an example and derive two different stiffness expressions using the integration method: One for a point load and another for a bending moment . When the boundary constraints are uniformly distributed, the minimum stiffness of the first and last cable segments increase linearly with an increase in the number of boundaries as shown in Figure 7(a), and correspondingly, more boundary constraints lead to the positions of minimum stiffness approaching the middle of the cable segments as Figure 7(b) shows. STEP 5: Evaluate the slope at the end node of the beam and rearrange equation in terms of stiffness. T0 > 2.0 × 105 N).
