315NGH test solution
PKG only status
Modal result ✓
HCF gload result ✓
Optimization plan
all plates thickness to 4mm
PKG is OK, not so much space for optimization
modify the CWT side frame design regionally==>next step
PKG with other components result
With all parts
freq and stress result
add the other part of the enclosure to check, floating bolt considered==>next step
all but Air cleaner
freq and stress result==>not useful
optimization plan
new bar connect the CWT side plate to upper frame==>next step
with brace connect the cab side plate to the upper frame==>no space, cancel this idea
315NGH compared to 313NGH and 317NGH layout
Enclosure weight info
Enclosure parts mount location
maybe some modal animation comparison
Yinlun weight prediction accuracy
