[ Abstract ] For special multi-axle vehicle, frame is the main support structure of the chassis. Except for standing all load cases of superstructure, frame must have enough strength and stiffness for all driving conditions. As the heaviest assembly of the chassis, frame should be designed as light as possible. Take HTF eight-axle special vehicle as example, the ANSYS and WORKWENCH are used to perform the mechanic analysis and optimization for static and multi-dynamic load cases, in which the forces of driving condition come from dynamic analysis of whole vehicle. The frame structure is optimized considering mechanics characteristic of all load cases, the goal of lightest design is achieved.

车架是多轴特种车辆的基础承力结构，其载荷可以分为两大类。第一类是上装设备工作过程中产生的载荷，如举升油缸对车架的作用力、调平过程中支腿油缸的反作用力等，此类载荷作用点相对集中，在计算和分析过程中一般按静态载荷处理；另一类是车辆在行驶过程中产生的动载，如行驶、转弯、制动等工况，此类载荷的特点是作用点分散，在时

动载荷应该怎么分析啊？
