【摘要】 从悬架的运动学和柔顺性(K&C)关系入手,以多体系统动力学为理论依据,建立了包含多种悬架的虚拟样机库。该虚拟样机库具有:①开放性。通过修改参数可以方便地构建用户自己的悬架虚拟样机;②实用性。虚拟样机库中的悬架都是企业实车悬架,对其仿真得出的悬架K&C特性具有重要的工程参考价值;③基础性。可快速构建多种前后悬架布置形式的整车虚拟样机。该虚拟样机为悬架产品乃至底盘产品的综合化、集成化、并行化设计打下了基础。更多还原

【Abstract】 Based on the theory of multi-body system dynamics,a virtual suspension prototype database was established from the suspension kinematics and compliance(K&C) relationships.The database includes many kinds of suspension,is characterized by following merits:(1)openness,the user may conveniently build its own suspension virtual prototype through parameter modification;(2)practicability,all suspensions included in the database are the real suspensions in the manufacturer products,the suspension K&C characteristis obtained from simulation are valuable for engineering reference;(3)basicness,whole vehicle virtual prototypes with different front and rear suspensions may be built from the database.The built database lays a foundation for synthesis,integration,and design parallelization of the vehicle suspension and even whole chassis product.更多还原
