摘　　要：对以往环模的受力分析方法的合理性进行了讨论,提出了一种新的分析方法。对模孔倒角处及模孔直孔部分的受力分析作了初步的探究,提出了农业纤维物料应力松弛特性是模孔内壁正压力及摩擦力产生的主要影响因素的观点,为正确设计颗粒机提供了科学依据。The rationality of force analysis method of the past circular mould is discussed, and then a new analysis method is put forward. The chamfering place and straight hole parts of mold hole are researched. The preview that the stress relaxation of agricultural fibrous material is the main influences of the normal pressure on the inside of mold hole and the friction is put for- ward, which provides scientific basis for the correct design of pellel feed machine.

关 键 词：环模 摩擦力 应力松弛特性
