Solid tires are rubber products, and deformation under pressure is a characteristic of rubber. When a solid tire is installed on a vehicle or machine and is subjected to load, the tire will deform vertically and its radius will become smaller. The difference between the radius of the tire and the radius of the tire without load is the deformation amount of the tire. The amount of deformation of solid tires is one of the considerations in tire selection during vehicle design. The main factors that affect the vertical deformation of solid tires are as follows:
1.Vertical radial force, the greater the vertical radial force experienced by a solid tire, the greater the compression deformation of the tire, and the greater its vertical deformation.
2. The hardness of the rubber material, the higher the hardness of the various rubber materials of solid tires, the smaller the deformation of the tire. Solid tires are usually composed of two or three rubber materials. The hardness of each rubber material is also different. When the proportion of various rubber materials changes, the deformation amount of the tire will also change. For example, when the base rubber with the highest hardness When the ratio increases, the deformation of the entire tire will become smaller.
3. Rubber layer thickness and tire cross-section width. The smaller the rubber layer thickness of a solid tire, the smaller the deformation amount. For solid tires of the same specification, the larger the cross-sectional width is, the smaller the deformation amount is under the same load.
4. Pattern and its depth. Generally, the greater the proportion of the pattern groove to the entire tread area, the deeper the pattern groove, the greater the deformation of the solid tire.
5. Influence of temperature, rubber will become softer at high temperatures and its hardness will decrease, so the deformation of solid tires will also increase at high temperatures.
