文摘
- •
The thermal hysteresis character of a large machine tool is analyzed.
- •
There is always hysteresis between environment temperature and thermal deformation.
- •
The hysteresis time fluctuates with seasonal weather and environmental temperature.
- •
An online temperature prediction analytical model is proposed for thermal analysis.
- •
An environmental temperature consideration thermal error prediction model is built.
