轮胎直压硫化内模适用范围与适用条件研究

针对金属内模的轮胎直压硫化机内模设计缺乏一般性公式，设计易失败的问题，提出一种利用MATLAB计算轮胎直压硫化内模具适用范围的研究方案。首先对常规直压硫化内模和改进的阶梯式直压硫化内模分别建立简化物理模型，以鼓瓦不干涉为条件建立约束方程，确定直压硫化内模的适用范围；进而建立任意规格轮胎是否适合直压硫化内模的判断公式，以探明轮胎直压硫化内模的适用范围，从而对任意规格轮胎直压硫化内模的设计提供参考数据。

The applicable scope and conditions of a direct-pressure vulcanization mould for tires

There are many advantages of using a metal mould in a tire vulcanizer compared with capsules. However, the design of metal moulds lacks a general formula and can easily fail. This paper proposes a research scheme based on MATLAB to calculate the applicable scope of a tire direct-pressure vulcanization mould. Firstly, a simplified physical model was established for a conventional direct-pressure vulcanization mould and an improved stepped direct-pressure vulcanization mould. Based on the non-interference of the drum, a constraint equation was established to determine the applicable scope of the direct-pressure vulcanization mould, and then a judgment formula was established for the application of the direct-pressure vulcanization mould for any size of tire. The design of the resulting mould for direct-pressure vulcanization of any size of tire provides useful reference data.
