摘　　要：弹簧是快速冲击夯的主要元件,其工作状况直接决定了机器的性能和寿命。因而,探索冲击夯弹簧工作的机理和受力状况,无疑具有极大的理论价值和实际指导意义。本文对此作了简要分析。The mechanical performance and servicelife of high speed impact rammer depend di-rectly on the operation conditions of its majorcomponent-the spring. Hence, the investiga-tion of operating mechanism and loading con-dition of spring in the rammer is undoubtedlyof considerable importance in theory and prac-tice, which are discussed in this article. Control of tractive force of parallel motorsystem in hydrostatic drive in wheel typeconstruction machinery Several methods of tractive force controland ship proof operation in hydrostatic drivewith parallel motors, that is, the application oftwin circuit, variable displacement motors cir-cuit, or adoption of flow divider, flow dividingvalve, and flow limiter etc., are introduced.
