随着工业的不断发展、对所用机械提出了朝着高速,高精度和自动化方向发展的要求,因而,对机构的分析和设计也提出了更高的要求,也就是说,用解析法进行机构分析和设计的必要性,已越来越明显。而且,在电子计算机和各种数控机床的出现和不断发展的今天,采用解析法的可能性亦已具备。因而,用解析法进行机构的分析和设计已有了更大的现实意义。 With the continuous development of the industry, the requirements for the machinery used in the direction of high speed, high precision and automation have been raised. Therefore, higher requirements have also been put on the analysis and design of institutions. In other words, The need for analysis and design has become increasingly evident. Moreover, with the emergence and continuous development of electronic computers and various CNC machine tools, the possibility of adopting analytical methods is also available. Therefore, using analytical methods for the analysis and design of institutions has greater practical significance.
