用于铣削动力学建模的稳定性叶瓣图分析（全离散法）(The full discrete method is used to map the stability lobe)

阵元间频率增量按对数增加，发射波束不再按距离周期性出现，发射波束图最大值只有一个。相较于阵元间频率增量固定的传统频率分集阵列，log-FDA能够抗距离相关的干扰，而且发射能量不泄露，具有一定的低截获性能。(FDA with logarithmically increasing frequency offset to achieve a beampattern with a single maximum at the target location. FDA radar with uniform interelement frequency offset, its beampattern exhibits maxima at multiple range values. doe tu the multiple maxima, a number of reflectors located at any of the maxima can interfere the target-return, thus deteriorating SINR.)

说明：  一受均匀拉力的板，中心带贯穿裂纹，裂纹长2a，使用4节点单元计算裂尖应力分布和应力强度因子(A uniform tensile plate with a through crack in the center and a crack length of 2a is used to calculate the stress distribution and stress intensity factor at the crack tip using a four node element)

用abaqus做的金属切削仿真，希望可以帮助大家(A metal cutting simulation, i hope it will be helpful)

魔术公式轮胎模型，纵向力，可调整轮胎侧偏刚度和纵向刚度等参数。(magic tire model. matlab/simulink m. longitudinal model. magic tire model. matlab/simulink m. longitudinal model)

说明：  利用TOA与最小二乘法直接求解（具有独立创新性），TDOA是利用拉格朗日法求解，而且里面的定位图解做得特别好，分别有一点定位，多点定位的的三维视觉图。(TOA is directly solved by least squares method(Innovativeness),TDOA is solved by Lagrange's method.)

说明：  实现多种二维面阵的综合设计，包括均匀阵、切比雪夫阵等等。。。。(Comprehensive design of various 2D arrays)
