基于简化简布法对条带作受力分析，条带中心处作用有重力Gi，在左边界作用

Based on the simplified simple cloth method, the force analysis of the strip is performed. The gravity Gi acts at the center of the strip, the supporting force Ei-1 of the next strip acts on the left boundary, and the thrust Ei of the previous strip acts on the right boundary. The contact surface has the supporting force of the substrate Ni and the anti-skid force Ri

Based on the force analysis of the stripe by simplified simplified simple method, the center of the strip has gravity Gi, the support force Ei-1 of the next band in the left boundary, the thrust Ei of the upper band in the right boundary, the support force Ni and anti-slip force Ri of the substrate in the contact surface.

Based on the simplified simple distribution method, the strip is subjected to gravity GI at the center of the strip, ei-1 for the next strip at the left boundary, ei-1 for the upper strip at the right boundary, Ni and RI for the base at the contact surface<br>
