The basis of formalization of the efficiency definition in this case using the notion of an absolute indicator properties Qi (i = 1,2... n), expressed in characteristic individual properties of the units (HAZ depth in microns, cutting speed in m/s, etc.).
In this regard, in addition, the weight coefficients Gi are set, which determine the relative "importance" of the i-th property on a single scale for all properties.
The normalized weights Hi = Gi/ΣGi, varying from 0 (for unimportant properties) to 1 (for important properties), are typically used for this purpose.

To go a step further, the ideal global optimum doesn’t exist, since the manufacturing factors cannot always be considered thoroughly.
The material properties are , and .
Pareto Plot is a graph that shows the effect of a factor or set of factors on a response by plotting the relationship as determined by regression analysis of the data set.
After analysis, the factors affect maximum displacement in torsion and bending condition are and , respectively, and the factors affect the modal frequency and volume are and .
Analysis based on Pareto Plot is done to find the design variables affecting the responses most.

The Improving Measures Research on the Cycle Life of Lead-acid Batteries for Electric Vehicles Lu Junmin1,a, Wang Xiaokan1,b 1Henan Mechanical and Electrical Vocational College, Xinzheng, 451191, China awxkbbg@163.com, bwangxiaokan@126.com Keywords: Grid alloys;Mixing Paste and Curing Process;The Negative Additive;The Combination of the Positive and Negative Plates Abstract.
By describing the main affecting factors of the small electric vehicles cycle life for the lead-acid batteries,then studying the main technical measures that how to improve the deep cycle performance of the batteries to prolong its life.When the methods of the combination of grid alloys ,mixing paste and curing process parameters control, the selection of the negative organic additives and the sets mode of the positive and negative plates were used,the battery performance and the cycle life greatly improved and the failure rate decreased.
This paper mainly introduces the main factors which influencing power battery life, and studies the main measures of improving the the deep circulation performance and service life.
The Main Influence Factors of the Power Battery Life The Corrosion Deformation of the Positive Plate When the battery is in the long deep discharge cycle,the positive plate will suffer corrosion, grid size will linearly increase, which resulted to ribs and border elongation deformation or fracture even occurs short circuit.Anatomizing the end life battery, the deformation and fracture,the irregular fracture penetration separator plate can be seen on both sides of the plate, the upper plate expansion to the bus and cause cell short-circuit phenomenon.Theory and Practice has proved that grid corrosion and deformation is one of the important causes of deep cycle battery life shortened,so the electrochemical properties of the power battery plate should be smaller corrosion rate and non intergranular corrosion,and also should have the appropriate hardness,strength and creep resistance on the mechanical properties.
