我厂84年设计的新产品集材50A拖拉机是经多次深入林区调查、访问用户和针对原J—50拖拉机二十年来使用、制造中发现的问题,参考国外集材拖拉机的先进结构和新型材料的基础上改进设计的。现仅就该拖拉机驾驶室设计中如何提高强度、改进性能的几个问题介绍如下。一、驾驶室安全性能的改进林区作业条件十分恶劣,拖拉机集材经常需要爬坡、钻树林、过倒木等。原J—50驾驶室是用1.2毫米的薄钢板点焊制成的,没有骨架,强度和刚度都很低,发生
The new product skidding 50A tractor designed by our factory in 84 years is a result of many in-depth forest surveys, user visits and problems found in the manufacture and use of the original J-50 tractor for 20 years. With reference to the advanced structure of a foreign tractor tractor New materials based on improved design. Here are just a few questions on how to improve the strength and improve performance of the tractor cab design. First, the improvement of cab safety performance Forest operating conditions are very poor, tractor skid often need to climb, drilling woods, over the wood and so on. The original J-50 cab is spot welded with 1.2 mm thin steel plate, has no skeleton, low strength and stiffness, occurs
