Interaction: Choose two factors to analysis their interaction effects, make the interaction table.
Three problems could be solved by Orthogonal Experiments: (1)　Analyze the relationship between the factors and the index, and find how the factors affecting the index
(2)　Analyze the primary factor and secondary factor affecting the index, find out the primary factor in many quotes influencing index, namely taking the main contradiction
(3)　Seek for the combination of the factors for the optimized index.

Now, there was usually using discrete way to analysis the mechanical properties of side-loading forklift truck lifting system.
But, this way consumed much times and works and also it could not reflect the entire mechanical properties of the lifting system.
So, in this article, we used the way of defining contact sets to achieve a comprehensive analysis of the mechanical properties of the lifting system, based on COSMOSWorks.
These holes diameter were usually small, and didn’t affected the mechanical properties of lifting system.
Furthermore we overall grasped the mechanical properties of lifting system, and ensured the safety and reliability of lifting system.
