长壁转载机支撑小车的优化设计

Optimization designing of carrier in longwall conveyor

本文运用强度理论，对长壁转载机的支撑小车进行了优化设计。在改进小车结构，改善应力状态及使用性能的基础上，通过强度、刚度等计算，选择优化设计参数，使设计结果更具合理性和可靠性。经试制一次成功，在实践中验证可行。

Carrier is redesigned by using strength theory,that structure is reasonable and reliable. Thecarrier had been put into operation in mine.
