摘　　要：为保证重型车载平台调平过程的稳定性和平台水平精度,研究平台调平过程中支点支撑力引起的平台变形,以及对平台空间位置变化和平台水平倾角检测的影响。分析基于水平倾角检测的平台调平时各支点垂直位移量约束关系,提出平台在最大稳定裕量状态下支点支撑力约束条件。利用ANSYS有限元分析方法对实车平台在稳定状态下因支撑力变化所产生的平台变形进行讨论,分析得到平台平面局部水平倾角变化范围超过3′。提出分布式水平倾角传感器安装和测量方案,并通过实验验证该方法有效。结果表明:车载平台调平精度高于1′,并保证平台快速、稳定和准确的调平要求。To ensure stability and accuracy of a vehicle platform in leveling process,the platform deformation caused by support forces of fulcrums during the leveling process and its influence on the spatial position change and the horizontal inclination of the platform are studied.Vertical displacement constraint condition of multi-supporting points of the platform in a stable state are analyzed,and constraint conditions of fulcrum support force under the condition of maximum stability margin are proposed.Using ANSYS,the platform deformation caused by support forces under stable state is discussed,and the horizontal inclination change in a local range is more than 3′.A distributed mounting scheme of horizontal inclination sensors is proposed.The experimental results show that the design ensures that the vehicle platform meets the requirements of fast,stable and accurate leveling,and the leveling accuracy of the platform is better than 1′.
