Material for diaphragm spring is 60Si2MnA its Elastic modulus and Poisson’s ratio is MPa and .
And then defining material properties, for diaphragm spring: 60Si2MnA, , , kg/mm3; and for pressure plate: 45 steel, , , kg/mm3.
For the free modal analysis of diaphragm spring, there was some basic setting and operative steps as same as those for statics analysis, including material properties, contact surfaces set, grid partition and loading operation.

Note：This research is one of the stage achievements in sports philosophy social science projects of Chinese General Administration of Sports"Yangtze River Delter Metropolitan Area Recreational sports development system research"(Grant No. 1602SS11010) 1 Introduction As an important power of society, culture and economy, recreation exerts great influence on the happiness and life satisfaction of every human being.
Design of questionnaire & Method of Data Processing In this study, it collects raw materials with the help of survey and software SPSS17.0 to make further statistical analysis.
Before that we need to identify the KMO value (Kaiser—Mcycr—Olkin Mersure of Sampling Adequacy ) and find out that KMO value of it is 0.737, The KMO value of Bartlett’s Test is above 0.7, and so the materials are suitable for factors analysis.

The various effects can’t be considered comprehensively under the traditional design methods of structural and material mechanics because of complicated stress state in pier.
The creep is an inherent characteristic of the concrete material and the deformation increases as the time under loads.
