The total plate thickness is divided in some layers , single direction and bi - directional machining , as well as before and after residual stress relieving , are simulated , the distortions by original residual stress in the plate arising are received , making the experimental plate ( 250 55 45mm ) , and the plate is machined , get its distortion , the simulating results are validated by distortion value of the experimental plate , there is odds between them , but their distortion trend are coincident 3 、研究了铝合金板材材料去除过程中由残余应力释放引起变形的数值求解方法。采用有限元的方法模拟了铝合金板材在不同工艺条件浙江工业大学硕士学位论文下残余应力释放引起的变形问题，并制备试验件进行了变形实验验证，数值模拟结果与实验结果基本吻合。
Based on the nonlinear model , the dynamic characteristic is simulated , by considering the influence of the environmental and geometrical factors , such as oil modulus , chamber volume etc . in chapter 5 , the dynamic mathematical model of the whole system is constructed considering the influence of vfvs electrical motor 第五章，给出了考虑变频电机后整个系统的数学模型，对其动态浙江工业大学硕士学位论文特性进行动态仿真，同时就系统各参数对系统工作特性的影响作了仔细分析。
According to study on magnetic parameters of the bounded ndfeb magnets : coercive force ( hc ) , residual magnetism intensity ( br ) , ( bh ) max . the residual magnetism intensity ( br ) and ( bh ) max of the bounded ndfeb magnets have not been evidently changed between that of cladded and non - cladded ndfeb magnetic powders 能够改善ndfeb磁体的导电性能的目的。浙江工业大学硕士学位论文包覆前后的粘接ndfeb磁体的矫顽力有不同程度地降低;而最大磁能积和剩余磁感应强度却变化不大。
The system has been successfully applied to a 300kn testing machine improvement in the central laboratory of mechanical engineering , zhejiang university of technology . what ' s more , with shanghai shenlian testing machine factory , microcomputer control hydraulic universal testing machine is developed . they can meet the control requirements of stress rate and strain rate in the international standard iso 6892 : 1998 ( e ) and the national standard gb228 - 2002 利用该系统已经对浙江工业大学机械基础中心实验室一台300kn试验机成功地进行了改造，并与上海申联试验机厂合作开发了微机控制液压万能试验机，满足国际标准iso6892 ： 1998 ( e )及国家标准gb228 - 2002对试验时的应力速率及应变速率的控制要求，在实际应用中取得了较好的效果。
To the problem which is met in the data structure and interface realization in the course of developing of this system , the interface realization technology based on vc mfc and manuscript api is proposed in the paper with secondary development technology of ug . it can effectively solve the problem that multi - interface functions of dll file used vc mfc under ug software presently 针对系统集成中数据结构与界面实现面临的问题，本文运用基于ug的二次开发技术，提出一种基于vcmfc和menuscriptapi交互式界面生成技术，有效地解决了动态链接库文件的多接口函数调浙江工业大学硕卜学位论文用问题。
