一、前言 机轮是直接关系到飞机安全的重要受力部件。随着我国航空技术的发展,对机轮的性能不断提出更高的要求,一般的铸造方法已不能适应,国外多数机种已应用铝合金模锻件代替铸件。我国由于受锻压设备和模锻技术的限制不得不采用“锻坯加工”,这不仅使机轮生产过程复杂化,增加了产品的成本,而且也保证不了质量。机轮生产工艺问题成为新机发展的关键之一。为了寻求机轮生产新途径,适应新机研制的需要,我们从 I. Introduction The wheel is an important force component that is directly related to the safety of the aircraft. With the development of China’s aviation technology, the performance of the wheel constantly put forward higher requirements, the general casting method has been unable to adapt to the majority of foreign models have been used aluminum forgings instead of castings. Due to the forging equipment and forging technology constraints in our country have to use “forging processing”, which not only makes the wheel production process more complex, increasing the cost of the product, but also can not guarantee the quality. The problem of wheel production technology has become one of the keys to the development of new aircraft. In order to seek a new way of wheel production, to meet the needs of new aircraft development, we from
