表面可脱模性预测模型
摘要：
本发明涉及一种估算使轮胎从模具中脱模的脱模力的估算方法，该方法涉及测量标准模具(2)和两个标准试样(3，4)的脱模力和成型面面积，所述方法包括：‑选择标准模具(2)的步骤，‑计算标准模具(2)的成型面面积S1的步骤，‑测量标准模具(2)的脱模力F1的步骤，‑确定具有成型面面积S0的第一标准试样(3)的步骤，‑确定具有成型面面积S’0的第二标准试样(4)的步骤，S’0与S0不同，‑测量第一标准试样(3)的脱模力F0的步骤，‑测量第二标准试样(4)的脱模力F’0的步骤，‑计算第一标准试样(3)的成型面面积S0与第二标准试样(4)的成型面面积S’0的比值以确定试样面积比Rse的步骤，‑计算第一标准试样(3)的脱模力F0与第二标准试样(4)的脱模力F’0的比值以确定试样力比Rfe的步骤，‑选取要测量模具(8，81，82)的步骤，‑计算要测量模具(8，81，82)的成型面面积Sm的步骤，‑计算要测量模具(8，81，82)的脱模力Fm的步骤，使得Fm＝F1×Sm/S1×Rfe/Rse。
摘要（英）：

The prediction model includes the steps of calculating a surface area S1 of a control mold, measuring the force F1 for demolding from the control mold, determining first and second test specimens with respective surface areas S0, S′0, measuring the force F0 for demolding from the first test specimen, measuring the force F′0 for demolding from the second test specimen, calculating the ratio of S0 and S′0 so as to define a test specimen surface area ratio Rse, calculating the ratio of the force F0 for demolding from the first test specimen and F′0 for demolding from the second test specimen so as to define a force ratio Rfe, measuring the molding surface area Sm of a mold to be measured and calculating the force Fm for demolding from the mold to be measured such that Fm=F1×Sm/S1×Rfe/Rse.
