前板簧悬架做static load时出错，无奈中，急

zwzhang

由前桥(fro_axle)模板+板簧(leaf)模板+testrig组装成fro_sus_assembly，设置好仿真参数后进行static load，最终出来以下信息：
---- ERROR ----
   ***** ADAMS MEMORY OVERFLOW *****
   A larger LD array is required.
   The error occurred in subroutine "DPVFC" while allocating "CHAR" space
   for the "second expression".
   Space Available:  0    Space Requested:  3
  
   ADAMS/Solver requires more program memory to run this model.
   Be aware that the above figures for Space available and Space
   requested only reflect the current requirements.  Additional space
   may be required later in the solution process.
  
   Several off-the-shelf memory configurations are available and
   custom configurations may be created.  The available memory models
   and the corresponding array sizes are:
       --------------------------
        NAME      LCEXPR   LDSIZ
       --------------------------
        STANDARD   100     2,000
        LARGE      200     2,000
        EX-LARGE   300     2,000
        HUGE       300     5,000
  
   where the columns correspond to:
       LCEXPR : Maximum number of lines in a Function
       LDSIZ  : Maximum total number of lines in all Functions
  
   To use an alternative setting, you have to start the ADAMS 'Settings'
   program.  It can be found using the Start menu:
  
     Start -> Programs -> MSC.Software -> MSC.ADAMS -> ADAMS-Settings
  
   Alternatively, you can start 'adams_settings.exe' in the 'utils\win32'
   folder of your ADAMS installation directory.

实在弄不明白，烦请高手指点一下。

在ADAMS的SETTING里修改下求解器内存量再试试吧。

ADAMS里面设置求解器的内存量估计不是很可行（曾经试过做大型的柔性体模型计算，不成功）
建议你在ADAMS2003里面做板簧，在自带的FLEX模块里面有一个做板簧的专门的自动柔性化模块，可以做（要添加环境变量），有做过尝试，可以仿真，但是刚度参数不好做。

将板簧离散梁的数量减少，需要内存就能少一些
