1 工程机械的数学描述机器的技术形态是由一组与结构和使用参数有联系的数学关系式和约束条件确定的。它是制定机器技术性能和绘制总图必要而又充分的数据。为了确定机器的技术形态,必须首先写出描述机器的数学模型。工程机械的数学描述包括以下内容: ①写出相应使用工况的机器运动方程式; 1 Mathematical description of the construction machinery The technical morphology of the machine is determined by a set of mathematical relationships and constraints that are related to the structure and the usage parameters. It is the necessary and sufficient data for the development of machine technical performance and the drawing of general drawings. In order to determine the technical form of the machine, a mathematical model describing the machine must first be written. The mathematical description of the construction machinery includes the following: 1 Write the machine motion equations for the corresponding operating conditions;
