    摘要:

    以某重型商用車駕駛室為研究對象，運用拓?fù)鋬?yōu)化設(shè)計方法對該駕駛室進(jìn)行輕量化分析與改進(jìn)設(shè)計，并與原駕駛室的性能進(jìn)行了對比。結(jié)果表明，輕量化駕駛室的結(jié)構(gòu)強(qiáng)度、剛度和低頻固有振動特性不低于原駕駛室，并使駕駛室抗前部擺錘沖擊和高頂駕駛室耐頂壓性能得到了改善。在不改變駕駛室結(jié)構(gòu)材料特性的條件下，使駕駛室質(zhì)量減小46 kg，取得了良好的輕量化效果。

    Abstract:

    A heavy-duty truck cab was analyzed and lightweight designed by using topological optimization method. Performance of the initial cab and lightweight structure was compared. It indicated that the front pendulum impact property of the cab and roof static pressure performances of the high-roof cab were improved when structural strength, rigidity and low-frequency natural vibration characteristics of the cab were not lower than the initial cab. Meanwhile, structural mass of the cab was reduced by 46 kg without changing of cab materials. A good lightweight design effect is acquired.
