本刊在81年第3期“掩护式液压支架的近似直线机构设计”一文中,对支架四连杆机构参数的确定推导了计算公式,并介绍了作图法。现又介绍一位设计工程师对四连杆机构的解析法设计经验,并在紧接的下一篇文章中介绍另一位设计工程师关于四连杆机构的作图法设计经验,提供了经验数据和论述,这对支架设计工作当有一定的参考价值。
In this paper, No. 81 of 81, “similar to the shield type hydraulic support straight-line design” article, the four-bar linkage bracket mechanism to determine the parameters derived from the calculation formula, and introduced the drawing method. Now introduced to a design engineer four-bar mechanism analytical method of design experience, and in the next article describes another design engineer on the four-bar linkage drawing method design experience, provides empirical data And discussion, this work on the stent design has a certain reference value.
