Force diagram of telescopic boom structure Evaluation Formula of Remaining Fatigue Life of Telescopic Boom for Mobile Crane Applying Paris-Erdogan to solve problem is on the premise that the material initial crack exist.
Paris formula is expressed as: (2) Where is crack length, is number of stress cycles, is stress intensity factor range, C, m are factors relate to materials and the shape of components.
The material of telescopic boom in this thesis is taken steel Q235, so m=3, C=2.55×10-13 are took.

Introduction According to the research, the real time of materials being processed which from raw materials into the plant to the finished products accounts for 5%~10% of the production cycle, however the time of warehouse and transport state accounts for 90%~95% [1].
It can reduce unnecessary materials transport, improve logistics efficiency and cut down logistics cost [3].
But in manufacturing, 20%~50% of the total operation cost is used by materials handing, so the saving of the cost of materials handing considered preferentially in the layout optimization design.

Engineering ceramic material has very broad application prospects in the field of mechanical, electronic, chemical, military, aviation and other industries[1-3].
On the other hand, with the decrease of the grinding wheel granularity, the depth and the force of grinding are also decreasing between single grits and ceramic material.
It increases plastic deformation removal of the ceramic material and reduces the brittleness removal which cause residual stress of grinding surface, so it helps to improve surface roughness.
