When the joints " distribution of the fixed platform and the moving platform are equal , judge the location is or not singularity . regard the determinant values of the jacobian matrix in flexible workspace as estimate guideline , which reduces extremely calculation that has been implemented in the singularity analyses of the 5 - dof parallel mechanism 本文在靈活工作空間內(nèi)以雅克比矩陣的行列式值作為評價指標(biāo),驗證當(dāng)定平臺和動平臺都是均布時機(jī)構(gòu)是否處于奇異位形,并在整個工作空間中搜索大大減少對并聯(lián)機(jī)床奇異位形分析的工作量。
