How to evaluate the impact of the elasticity of polyurethane solid forklift tires on the operating comfort of forklifts?

The elasticity of polyurethane solid forklift tires is a key factor affecting the operating comfort of forklifts. The following are several ways to evaluate its impact.
1. Vibration test
Vibration sensors can be installed at key parts of forklifts, such as seats and operating handles. When the forklift is driving on different road conditions (such as flat concrete, slightly bumpy stone roads, and gapped workshop floors), record the vibration data of these parts. Polyurethane solid tires with good elasticity can effectively absorb the bumps on the road and reduce the vibration transmitted to the forklift body and operators. By comparing the vibration amplitude and frequency when installing tires with different elasticity, you can intuitively understand the impact of tire elasticity on comfort. For example, if the same road section is passed at the same speed, the peak value of the vibration acceleration of the forklift seat installed with high elastic tires is much lower than that of the forklift with low elastic tires, which shows that high elastic tires can significantly improve comfort.
2. Driver subjective evaluation
Organize experienced forklift drivers to experience actual operation. Ask them to drive forklifts with different elastic polyurethane solid tires in the same or similar working environment, and evaluate the comfort according to their own feelings. The evaluation content may include the degree of fatigue during driving, the perception of bumps, the ease of operation, etc. For example, the driver may report that the tire with good elasticity feels more stable during driving, the fatigue of the body is significantly reduced after long-term driving, and the steering of the forklift is smoother, because the good elasticity reduces the additional resistance and shaking caused by uneven road surface.
3. Pressure distribution measurement
Install the pressure distribution measurement pad on the surface of the forklift seat to measure the pressure distribution between the driver's body and the seat during operation. Tires with appropriate elasticity can make the pressure distribution more uniform during driving and avoid excessive local pressure. When the tire is not elastic enough, the vibration of the forklift may cause the driver to shake frequently on the seat, so that the pressure is concentrated in certain parts, causing discomfort. By analyzing the pressure distribution data, such as pressure peak, average pressure, uniformity of pressure distribution and other indicators, the effect of tire elasticity on comfort can be evaluated. At the same time, combined with factors such as forklift driving speed and road conditions, a more comprehensive analysis of the performance of tires with different elasticity under different working conditions is conducted, thereby providing a basis for selecting Polyurethane solid forklift tires with appropriate elasticity and improving the comfort of forklift operation.
